Long-term outcomes of autologous vein bypass for repair of upper and lower extremity major arterial trauma. J Vasc Surg 2024; 79:1339-1346. [PMID: 38301809 DOI: 10.1016/j.jvs.2024.01.204] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/22/2023] [Revised: 01/12/2024] [Accepted: 01/25/2024] [Indexed: 02/03/2024]
Abstract
OBJECTIVE Autologous vein is the preferred bypass conduit for extremity arterial injuries owing to superior patency and low infection risk; however, long-term data on outcomes in civilians are limited. Our goal was to assess short- and long-term outcomes of autologous vein bypass for upper and lower extremity arterial trauma. METHODS A retrospective review was performed of patients with major extremity arterial injuries (2001-2019) at a level I trauma center. Demographics, injury and intervention details, and outcomes were recorded. Primary outcomes were primary patency at 1 year and 3 years. Secondary outcomes were limb function at 6 months, major amputation, and mortality. Multivariable analysis determined risk factors for functional impairment. RESULTS There were 107 extremity arterial injuries (31.8% upper and 68.2% lower) treated with autologous vein bypass. Mechanism was penetrating in 77% of cases, of which 79.3% were due to firearms. The most frequently injured vessels were the common and superficial femoral (38%), popliteal (30%), and brachial arteries (29%). For upper extremity trauma, concomitant nerve and orthopedic injuries were found in 15 (44.1%) and 11 (32.4%) cases, respectively. For lower extremities, concomitant nerve injuries were found in 10 (13.7%) cases, and orthopedic injuries in 31 (42.5%). Great saphenous vein was the conduit in 96% of cases. Immediate intraoperative bypass revision occurred in 9.3% of patients, most commonly for graft thrombosis. The in-hospital return to operating room rate was 15.9%, with graft thrombosis (47.1%) and wound infections (23.5%) being the most common reasons. The median follow-up was 3.6 years. Kaplan-Meier analysis showed 92% primary patency at 1 year and 90% at 3 years. At 6 months, 36.1% of patients had functional impairment. Of patients with functional impairment at 6 months, 62.9% had concomitant nerve and 60% concomitant orthopedic injuries. Of those with nerve injury, 91.7% had functional impairment, compared with 17.8% without nerve injury (P < .001). Of patients with orthopedic injuries, 51.2% had functional impairment, vs 25% of those without orthopedic injuries (P = .01). On multivariable analysis, concomitant nerve injury (odds ratio, 127.4; 95% confidence interval, 17-957; P <. 001) and immediate intraoperative revision (odds ratio, 11.03; 95% confidence interval, 1.27-95.55; P = .029) were associated with functional impairment. CONCLUSIONS Autologous vein bypass for major extremity arterial trauma is durable; however, many patients have long-term limb dysfunction associated with concomitant nerve injury and immediate intraoperative bypass revision. These factors may allow clinicians to identify patients at higher risk for functional impairment, to outline patient expectations and direct rehabilitation efforts toward improving functional outcomes.

Concomitant vascular and orthopedic trauma: 10 points to consider. J Clin Orthop Trauma 2024; 51:102407. [PMID: 38681997 PMCID: PMC11053217 DOI: 10.1016/j.jcot.2024.102407] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/16/2022] [Revised: 04/01/2024] [Accepted: 04/11/2024] [Indexed: 05/01/2024] Open
Abstract
Although vascular injuries complicate only 1-2% of patients with orthopedic trauma, they may be encountered in a much higher rate of around 10 % in injuries around the knee and elbow joints following both fractures and dislocations. In case of vascular involvement, specific diagnostic and therapeutic challenges arise and there is a higher risk for significant morbidity (i.e. limb loss) or mortality. In the absence of randomized data, diagnostic and therapeutic algorithms are not always straightforward and clinical practice may be based on experience and local protocols rather than firm evidence. With this article we intend to review available literature regarding concomitant skeletal and vascular trauma in order to provide concise information and clear guidelines of when to operate with least investigations and when to go for a full spectrum of investigations in the absence of hard clinical signs. Additionally, other aspects concerning the manipulation of these patients are discussed, such as the indications of primary amputation, the potential role of endovascular techniques and the value of the Resuscitative Endovascular Balloon Occlusion of the Aorta. In summary, this scoping review summarizes current practices in the diagnostic and therapeutic management of patients with concomitant orthopedic and vascular injuries, discusses different treatment strategies and gives a practical perspective for implementation on every day practice.

Current outcomes following upper and lower extremity arterial trauma from the National Trauma Data Bank. J Vasc Surg 2024:S0741-5214(24)00925-X. [PMID: 38570174 DOI: 10.1016/j.jvs.2024.03.438] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/04/2023] [Revised: 03/07/2024] [Accepted: 03/25/2024] [Indexed: 04/05/2024]
Abstract
OBJECTIVE The modern treatments of trauma have changed in recent years. We aim to evaluate the factors associated with limb salvage and mortality after extremity arterial trauma, especially with respect to the type of conduit used in revascularization. METHODS The National Trauma Data Bank was queried to identify patients with upper and lower extremity (UE and LE) arterial injuries between 2016 and 2020. The patients were stratified by the types of arterial repair. The primary outcome was in-hospital mortality. RESULTS 8780 patients were found with 5054 (58%) UE and 3726 (42%) LE injuries. Eighty-three percent were men, and the mean age was 34 ± 15 years. Penetrating mechanism was the predominant mode of injury in both UEs and LEs (73% and 67%, respectively) with a mean injury severity score of 14 ± 8. For UEs, the majority underwent primary repair (67%, P < .001), whereas the remainder received either a bypass (20%) or interposition graft (12%). However, LEs were more likely to receive a bypass (52%, P < .00001) than primary repair or interposition graft (34% and 14%, respectively). Compared with the extremely low rates of amputation and mortality among UE patients (2% for both), LE injuries were more likely to result in both amputation (10%, P < .001) and death (6%, P < .001). Notably, compared with primary repair, the use of a prosthetic conduit was associated with a 6.7-fold increase in the risk of amputation in UE and a 2.4-fold increase in LE (P < .0001 for both). Synthetic bypasses were associated with a nearly 3-fold increase in return to the operating room (OR) in UE bypasses (P < .05) and a 2.4-fold increase in return to the OR in LE bypasses (P < .0001). CONCLUSIONS In recent years, most extremity vascular trauma was due to penetrating injury with a substantial burden of morbidity and mortality. However, both limb salvage rates and survival rates have remained high. Overall, LE injuries more often led to amputation and mortality than UE injuries. The most frequently used bypass conduit was vein, which was associated with less risk of unplanned return to the OR and limb loss, corroborating current practice guidelines for extremity arterial trauma.

Vascular complications secondary to resuscitative endovascular balloon occlusion of the aorta placement at a Level 1 Trauma Center. J Vasc Surg 2024:S0741-5214(24)00499-3. [PMID: 38493898 DOI: 10.1016/j.jvs.2024.03.020] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/18/2023] [Revised: 03/05/2024] [Accepted: 03/10/2024] [Indexed: 03/19/2024]
Abstract
INTRODUCTION Resuscitative endovascular balloon occlusion of the aorta (REBOA) is designed to manage severe hemorrhagic shock. Popularized in medical care during military conflicts, the concept has emerged as a lifesaving technique that is utilized around the United States. Literature on risks of REBOA placement, especially vascular injuries, are not well-reported. Our goal was to assess the incidence of vascular injury from REBOA placement and the risk factors associated with injury and death among these patients at our institution. METHODS We performed a retrospective cohort study of all patients who underwent REBOA placement between September 2017 and June 2022 at our Level 1 Trauma Center. The primary outcome variable was the presence of an injury related to REBOA insertion or use. Secondary outcomes studied were limb loss, the need for dialysis, and mortality. Data were analyzed using descriptive statistics, χ2, and t-tests as appropriate for the variable type. RESULTS We identified 99 patients who underwent REBOA placement during the study period. The mean age of patients was 43.1 ± 17.2 years, and 67.7% (67/99) were males. The majority of injuries were from blunt trauma (79.8%; 79/99). Twelve of the patients (12.1%; 12/99) had a vascular injury related to REBOA placement. All but one required intervention. The complications included local vessel injury (58.3%; 7/12), distal embolization (16.7%; 2/12), excessive bleeding requiring vascular consult (8.3%; 1/12), pseudoaneurysm requiring intervention (8.3%; 1/12), and one incident of inability to remove the REBOA device (8.3%; 1/12). The repairs were performed by vascular surgery (75%; 9/12), interventional radiology (16.7%; 2/12), and trauma surgery (8.3%; 1/12). There was no association of age, gender, race, and blunt vs penetrating injury to REBOA-related complications. Mortality in this patient population was high (40.4%), but there was no association with REBOA-related complications. Ipsilateral limb loss occurred in two patients with REBOA-related injuries, but both were due to their injuries and not to REBOA-related ischemia. CONCLUSIONS Although vascular complications are not unusual in REBOA placement, there does not appear to be an association with limb loss, dialysis, or mortality if they are addressed promptly. Close coordination between vascular surgeons and trauma surgeons is essential in patients undergoing REBOA placement.

Long-term functional outcomes of upper extremity civilian vascular trauma. J Vasc Surg 2024; 79:526-531. [PMID: 37992948 DOI: 10.1016/j.jvs.2023.11.028] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/25/2023] [Revised: 11/13/2023] [Accepted: 11/16/2023] [Indexed: 11/24/2023]
Abstract
OBJECTIVE Civilian analyses of long-term outcomes of upper extremity vascular trauma (UEVT) are limited. Our goal was to evaluate the management of UEVT in the civilian trauma population and explore the long-term functional consequences. METHODS A retrospective review and analysis was performed of patients with UEVT at an urban Level 1 trauma center (2001-2022). Management and long-term functional outcomes were analyzed. RESULTS There were 150 patients with UEVT. Mean age was 34 years, and 85% were male. There were 42% Black and 27% White patients. Mechanism was penetrating in 79%, blunt in 20%, and multifactorial in 1%. Within penetrating trauma, mechanism was from firearms in 30% of cases. Of blunt injuries, 27% were secondary to falls, 13% motorcycle collisions, 13% motor vehicle collisions, and 3% crush injuries. Injuries were isolated arterial in 62%, isolated venous in 13%, and combined in 25% of cases. Isolated arterial injuries included brachial (34%), radial (27%), ulnar (27%), axillary (8%), and subclavian (4%). The majority of arterial injuries (92%) underwent open repair with autologous vein bypass (34%), followed by primary repair (32%), vein patch (6.6%), and prosthetic graft (3.3%). There were 23% that underwent fasciotomies, 68% of which were prophylactic. Two patients were managed with endovascular interventions; one underwent covered stent placement and the other embolization. Perioperative reintervention occurred in 12% of patients. Concomitant injuries included nerves (35%), bones (17%), and ligaments (16%). Intensive care unit admission was required in 45%, with mean intensive care unit length of stay 1.6 days. Mean hospital length of stay was 6.7 days. Major amputation and in-hospital mortality rates were 1.3% and 4.6% respectively. The majority (72%) had >6-month follow-up, with a median follow-up period of 197 days. Trauma readmissions occurred in 19%. Many patients experienced chronic pain (56%), as well as motor (54%) and sensory (61%) deficits. Additionally, 41% had difficulty with activities of daily living. Of previously employed patients (57%), 39% experienced a >6-month delay in returning to work. Most patients (82%) were discharged with opioids; of these, 16% were using opioids at 6 months. CONCLUSIONS UEVT is associated with long-term functional impairments and opioid use. It is imperative to counsel patients prior to discharge and ensure appropriate follow-up and therapy.

Incidence and characteristics of vascular trauma at a level 2 trauma center. J Vasc Surg 2024; 79:11-14. [PMID: 37742731 DOI: 10.1016/j.jvs.2023.09.025] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/05/2023] [Revised: 09/12/2023] [Accepted: 09/17/2023] [Indexed: 09/26/2023]
Abstract
OBJECTIVE Despite the significant number of trauma patients treated at level 2 trauma centers (L2TCs) in the United States, most of the literature describing vascular trauma is from level 1 trauma centers (L1TCs). Currently, trauma center designation criteria do not require vascular surgery as a necessary component service. METHODS A retrospective chart review was performed for all trauma patients with a vascular surgery consultation seen at our L2TC between 2013 and 2018. Patient demographics, injury characteristics, and outcomes were collected and analyzed with descriptive statistics. RESULTS Of the 3062 trauma patients evaluated at our L2TC, 110 (3.6%) had a vascular surgery consultation. Operative intervention was performed in 35.2% of consults, and 1.0% of all trauma patients had a vascular intervention. Average age was 57 years, and the majority were male (n = 75; 68.2%). Mean Injury Severity Score was 12.0 ± 9.6, and blunt injury (n = 77; 87.5%) was more common than penetrating (n = 11; 12.5%). The most common location of injury was the lower extremity (n = 23; 74.2%), followed by upper extremity (n = 3; 9.7%), chest (n = 2; 6.5%), neck (n = 2; 6.5%), and pelvis (n = 1; 3.2%). Endovascular interventions were performed by the vascular surgery service in 67.7% (n = 21) of all injuries. There was one amputation (3.2%) and one postoperative mortality (3.2%). CONCLUSIONS At our L2TC, postoperative morbidity and mortality rates at 30 days were substantially lower compared with previously reported data. However, mean injury severity score and the incidence of penetrating and polytrauma were also lower at our institution. Most patients were managed nonoperatively, but when they did require an operation, endovascular therapies were more commonly implemented. Vascular surgery should be considered an integral service in trauma level designation, and there is a need for further investigation of these outcomes in L2TCs.

Editor's Choice - In Hospital and Long Term Outcomes After Repair of Subclavian and Axillary Artery Injuries. Eur J Vasc Endovasc Surg 2023; 66:840-847. [PMID: 37567338 DOI: 10.1016/j.ejvs.2023.08.008] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/26/2023] [Revised: 07/21/2023] [Accepted: 08/04/2023] [Indexed: 08/13/2023]
Abstract
OBJECTIVE To evaluate the in hospital and long term outcomes after open or endovascular repair of subclavian and axillary artery injuries. METHODS This was a retrospective, single centre study. Data were reviewed from patients with subclavian and or axillary injuries who presented to the authors' centre between January 2009 and December 2022. Outcome data included complications, death, amputations, and re-interventions. A p value < .050 was considered to be statistically significant. RESULTS Over the study period, 62 patients with subclavian or axillary trauma were admitted to the study hospital. Patients were young (median age 32.5 years, range 12 - 53) and most were men (85%); 32 patients experienced blunt trauma, and 30 penetrating trauma. The median injury severity score was 18 (interquartile range [IQR] 9, 34), and 47% of patients had a brachial plexus injury. The arterial injury was occlusion in 62% of patients, and the median ischaemia time was 12.5 hours (IQR 7.13, 24). All patients with subclavian injuries (n = 37) and 13 of 25 patients with an axillary injury underwent endovascular repair (stent graft placement). Open repair was performed in 12 patients with axillary injury (axillobrachial bypass in seven patients). At hospital discharge, the amputation free survival rate was 82% vs. 92% (p = .67), the mortality rate was 10% vs. 8% (p = 1.0), and the amputation rate was 10% vs. 0 (p = .57) for endovascular and open repair, respectively. The mean follow up time was 4.1 ± 3.5 years. After the seven year follow up, the stent primary patency was 42%. No re-interventions or amputations were performed after hospital discharge. Disability was related to fractures and soft tissue and brachial plexus injuries. CONCLUSION Endovascular treatment was preferred for patients with subclavian artery injuries. Open repair was preferred for patients with penetrating axillary injuries. In hospital and long term complications were related to fractures and soft tissue and brachial plexus injuries, rather than the treatment of arterial injuries. Measures are needed to reduce ischaemia time and improve brachial plexus injury repair.

Diagnostic accuracy study of the clinical indicators of vascular trauma in patients undergoing antineoplastic chemotherapy in peripheral veins. JOURNAL OF VASCULAR NURSING 2023; 41:149-152. [PMID: 38072565 DOI: 10.1016/j.jvn.2023.06.002] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/08/2021] [Revised: 06/17/2023] [Accepted: 06/19/2023] [Indexed: 12/18/2023]
Abstract
Antineoplastic chemotherapy patients are susceptible to vascular trauma. The identification of this problem is possible through accurate clinical indicators. However, there are few diagnostic accuracy studies of vascular trauma in these patients. Thus, the objective was to analyze the accuracy of clinical indicators of vascular trauma in antineoplastic chemotherapy patients. A diagnostic accuracy study was carried out with a sample of 200 patients undergoing antineoplastic chemotherapy, in an oncology reference clinic, during 2018. A data collection form was created with sociodemographic and clinical data and indicators of vascular trauma. The sensitivity and specificity of the clinical indicators were assessed using a latent class analysis of random effects. The clinical indicators of decreased vascular elasticity (0.8384), pain (0.9573), and signs of infection at the catheter insertion site (0.9999) were specific for identifying vascular trauma in antineoplastic chemotherapy patients. The prevalence of vascular trauma in these patients was 11.17%. A set of three clinical indicators was considered accurate and statistically significant for confirming vascular trauma. This study has provided accurate clinical indicators of vascular trauma in antineoplastic chemotherapy patients. These results can contribute to establishing interventions, thereby reducing costs and maximizing health outcomes in this population.

Persistent pseudoaneurysm after non-operative management of a Grade 4 liver injury. Trauma Case Rep 2023; 48:100946. [PMID: 37822491 PMCID: PMC10562760 DOI: 10.1016/j.tcr.2023.100946] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 09/22/2023] [Indexed: 10/13/2023] Open
Abstract
A hepatic pseudoaneurysm (HPA) after blunt or penetrating liver injury is an unusual but potentially lethal complication that can develop from an injured hepatic artery branch [1-5]. Endovascular intervention with coil embolization to treat HPA is a safe and effective method and has become the standard first-line treatment, with a success rate achieving 70-100 % [13,14,15]. Infrequently the pseudoaneurysm is fed by collateral vessels and endovascular intervention may be unsuccessful. Other minimally invasive treatment options that can be considered include image guided percutaneous thrombin injection, endovascular placement of covered stents and injection of liquid agents such as fibrin glue [10,11]. We present a case of a young female who developed a post-traumatic persistent hepatic pseudoaneurysm requiring a total of nine interventions, including six endovascular interventions with angiography, three endoscopic procedures for bleeding, one percutaneous injection, and two re-admissions to the hospital. Although she avoided initial operative management, her three-month hospital course can be considered a failure of conservative management of blunt hepatic trauma due to the accrued health care costs and resources. The literature on the management of persistent pseudoaneurysm is limited. The decision to treat a persistent HPA that are found incidentally and stable in size needs further investigation.

Abstract
PURPOSE Vascular injuries in lower extremity trauma, especially with involvement of the popliteal artery, are associated with considerably high rates of limb loss, especially with blunt trauma mechanisms. The aim of this study was to evaluate the risk of amputation in patients with traumatic popliteal artery lesions with special focus on the validity of the Mangled Extremity Severity Score (MESS). METHODS In this retrospective study, all patients treated for isolated lesions of the popliteal artery following trauma between January 1990 and December 2020 at a high-volume level I trauma center were included. Primary outcome was limb salvage dependent on MESS and the influence of defined parameters on limb salvage was defined as secondary outcome. The extent of trauma was assessed by the MESS. RESULTS A total of 50 patients (age 39.2 ± 18.6 years, 76% male) with most blunt injuries (n = 47, 94%) were included. None of the patients died within 30 days and revascularization was attempted in all patients with no primary amputation and the overall limb salvage rate was 88% (44 patients). A MESS ≥ 7 was observed in 28 patients (56%) with significantly higher rates of performed fasciotomies (92.9% vs. 59.1%; p < 0.01) in those patients. MESS did not predict delayed amputation within our patient cohort (MESS 8.4 ± 4.1 in the amputation group vs. 8.1 ± 3.8 in the limb salvage group; p = 0.765). CONCLUSION Revascularization of limbs with isolated popliteal artery injuries should always be attempted. MESS did not predict delayed amputation in our cohort with fasciotomy being an important measure to increase limb salvage rates.

Review of surgical treatment of iatrogenic iliofemoral artery injury in the pediatric population after catheterization. Eur J Med Res 2023; 28:521. [PMID: 37968770 PMCID: PMC10652633 DOI: 10.1186/s40001-023-01510-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/25/2023] [Accepted: 11/05/2023] [Indexed: 11/17/2023] Open
Abstract
Trauma is the leading cause of death in the pediatric population. Although vascular trauma has an incidence of 6% in civilian population, iatrogenic injuries are the leading cause, and the most frequent injured vessel is the iliofemoral sector. However, little information is available and there are no guidelines about its treatment. Therefore, this review aimed to describe the information available concerning pediatric iatrogenic arterial trauma, focusing on the iliofemoral segment and present 3 cases. We described 11 articles with 171 patients, of whom 61% underwent surgery to treat iatrogenic trauma. Mean age was 3.28 years (standard deviation of 3.5 years), and 54% were female. Most iliofemoral injuries occurred after arterial catheterization for hemodynamic monitorization and therapeutic or diagnostic cardiac catheterization (due to congenital heart diseases, including septal defects, tetralogy of Fallot, aortic coarctation, and patent ductus arteriosus). For acute complications, arterial thrombosis was the leading injury, followed by pseudoaneurysm, hematoma, dissection, transection, avulsion, eversion, and combined lesions.

Association between time to revascularization and limb loss in military femoropopliteal arterial injuries. J Vasc Surg 2023; 78:1198-1203. [PMID: 37541556 DOI: 10.1016/j.jvs.2023.07.055] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/21/2023] [Revised: 07/23/2023] [Accepted: 07/25/2023] [Indexed: 08/06/2023]
Abstract
OBJECTIVE Expeditious revascularization is key to limb salvage after arterial injuries, but the relationship between time to revascularization and amputation risk is not well-defined. We aimed to explore amputation risk based on time to revascularization in a cohort of military femoropopliteal arterial injuries. METHODS A database of vascular injuries from Iraq and Afghanistan casualties (2004-2012) was queried for femoral (common, superficial, or deep) and/or popliteal arterial injuries that underwent revascularization. Time from injury to initial revascularization (via shunt or reconstruction) was divided into groups of <3 hours, 3 to 6 hours, 6 to 9 hours, and >9 hours, and bivariate comparisons were performed. RESULTS Revascularization times were available for 120 cases. Injury and treatment characteristics by time group were generally similar between time groups. Shunting and vein injuries were more common in limbs revascularized earlier, whereas blast mechanism and fasciotomy were more common with later revascularization. Ten cases (8%) underwent revascularization in less than 3 hours, 63 (53%) were revascularized in 3 to 6 hours, 33 (28%) in 6 to 9 hours, and 14 (12%) after 9 hours. Amputation rates within the cohorts were 10%, 21%, 24%, and 50%, respectively (P = .085, χ2 of amputation rates across time groups). The mean ± standard deviation revascularization time for amputated limbs was 442 ± 348 minutes vs 347 ± 183 minutes for salvaged limbs (P = .057). Amputation was performed in 19% of limbs revascularized in <6 hours and in 32% revascularized >6 hours from injury (P = .112). The >9-hour group, however, had a 50% amputation rate vs 21% for those with revascularization in <9 hours (P = .016). Fractures were more common in >9-hour limbs than <9-hour limbs (79% vs 44%; P = .016), but other limb injury characteristics were similar, with no difference in limb injury severity scores. Among 91 salvaged limbs, neither vascular nor other complications were predicted by time to revascularization. All seven >9-hour limbs had a limb complication, most commonly infection (71%), and three (42%) required a skin graft to close their fasciotomies. CONCLUSIONS Increasing time from injury to initial revascularization was associated with increasing rates of limb loss. Revascularization within 3 hours of injury resulted in a low amputation rate, whereas one-half of limbs treated after 9 hours were amputated. Arterial shunting was associated with earlier revascularization and should be considered a mainstay of combat casualty vascular care. Forward-deployed surgical assets play a pivotal role in providing early revascularization and reducing rates of limb loss in modern combat casualty care.

Major vascular traumas to the neck, upper limbs, and chest: Clinical presentation, diagnostic approach, and management strategies. Semin Vasc Surg 2023; 36:258-267. [PMID: 37330239 DOI: 10.1053/j.semvascsurg.2023.04.010] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/03/2023] [Revised: 04/14/2023] [Accepted: 04/17/2023] [Indexed: 06/19/2023]
Abstract
Major vascular traumas to the neck, upper limbs, and chest may arise from penetrating and/or blunt mechanisms, resulting in a range of clinical scenarios. Lesions to the carotid arteries may also lead to neurologic complications, such as stroke. The increasing use of invasive arterial access for diagnostic and/or interventional purposes has increased the rate of iatrogenic injuries, which usually occur in older and hospitalized patients. Bleeding control and restoration of perfusion represent the two main goals of treatment for vascular traumatic lesions. Open surgery still represents the gold standard for most lesions, although endovascular approaches have increasingly emerged as feasible and effective options, particularly for management of subclavian and aortic injuries. In addition to advanced imaging (including ultrasound, contrast-enhanced cross-sectional imaging, and arteriography) and life support measures, multidisciplinary care is required, particularly in the setting of concomitant injuries to the bones, soft tissues, or other vital organs. Modern vascular surgeons should be familiar with the whole armamentarium of open and endovascular techniques needed to manage major vascular traumas safely and promptly.

Epidemiology and Outcomes of Peripheral and Non-Aortocaval Vascular Trauma in Scotland 2011 - 2018. Eur J Vasc Endovasc Surg 2023; 65:444-448. [PMID: 36464220 DOI: 10.1016/j.ejvs.2022.11.020] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/30/2022] [Revised: 10/31/2022] [Accepted: 11/26/2022] [Indexed: 12/05/2022]
Abstract
OBJECTIVE This population based study aimed to examine the demographics, mechanisms, and outcomes of patients in Scotland suffering peripheral and non-aortocaval vascular trauma between 2011 and 2018. METHODS A retrospective observational study was conducted using prospectively collected data derived from the Scottish Trauma Audit Group (STAG) from 1 January 2011 to 31 December 2018. Peripheral and non-aortocaval vascular trauma patients were identified using Abbreviated Injury Severity (AIS) codes. Demographics, mechanisms, types of injury, severity, and outcomes were analysed. RESULTS Of 30 831 patients admitted with trauma to Scottish hospitals, 569 (1.8%) patients suffered a vascular injury during the eight year study period with 275 (0.9%) patients sustaining a peripheral or non-aortocaval vascular injury. There were 221 (80%) men and 54 (20%) women with a median (range) age of 39 (14 - 88) years. Blunt trauma was responsible for 179 (65%) injuries, of which road traffic accidents were the most common mechanism. A further 67 (24%) injuries were due to penetrating trauma, of which assault was the most common cause. The most common injury was to abdominal arteries (e.g., hepatic, renal, splenic [n = 83]) with an associated mortality rate of 17%. The median (range) Injury Severity Score (ISS) was 16 (4 - 75). Sixteen (6%) patients died in the Emergency Department (ED). Two hundred and twenty-seven (83%) patients were taken to theatre during their admission with a 30 day peri-operative mortality rate of 10%, compared with an overall mortality rate of 16%. Injuries to an abdominal vein (e.g., portal, renal, splenic, superior mesenteric) had the highest number of associated deaths, with 11 (32%) of 34 cases resulting in a fatality. CONCLUSION There is a low incidence of vascular trauma in Scotland. Blunt force was responsible for more vascular injuries than penetrating trauma. Patients with peripheral and non-aortocaval vascular injuries are likely to be severely injured and suffer a high mortality rate.

Abstract
In the United States, gunshot wounds (GSWs) have become a critical public health concern with substantial annual morbidity, disability, and mortality. Vascular injuries associated with GSW may pose a clinical challenge to the physicians in the emergency department. Patients demonstrating hard signs require immediate intervention, whereas patients with soft signs can undergo further diagnostic testing for better injury delineation. Although digital subtraction angiography is the gold standard modality to assess vascular injuries, non-invasive techniques such as Doppler ultrasound, computed tomography angiography, and magnetic resonance angiography have evolved as appropriate alternatives. This article discusses penetrating bodily vascular injuries, specifically ballistic and stab wounds, and the corresponding radiological presentations.

Female sex is independently associated with reduced inpatient mortality after endovascular repair of blunt thoracic aortic injury. J Vasc Surg 2023; 77:56-62. [PMID: 35944732 DOI: 10.1016/j.jvs.2022.07.178] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/18/2022] [Revised: 06/21/2022] [Accepted: 07/19/2022] [Indexed: 02/03/2023]
Abstract
BACKGROUND Female sex has been associated with decreased mortality after blunt trauma, but whether sex influences the outcomes of thoracic endovascular aortic repair (TEVAR) for traumatic blunt thoracic aortic injury (BTAI) is unknown. METHODS In this retrospective study of a prospectively maintained database, the Vascular Quality Initiative registry was queried from 2013 to 2020 for patients undergoing TEVAR for BTAI. Univariate Student's t-tests and χ2 tests were performed, followed by multivariate logistic regression for variables associated with inpatient mortality. RESULTS Of 806 eligible patients, 211 (26.2%) were female. Female patients were older (47.9 vs 41.8 years, P < .0001) and less likely to smoke (38.3% vs 48.2%, P = .044). Most patients presented with grade III BTAI (54.5% female, 53.6% male), followed by grade IV (19.0% female, 19.5% male). Mean Injury Severity Scores (30.9 + 20.3 female, 30.5 + 18.8 male) and regional Abbreviated Injury Score did not vary by sex. Postoperatively, female patients were less likely to die as inpatients (3.8% vs 7.9%, P = .042) and to be discharged home (41.4% vs 52.2%, P = .008). On multivariate logistic regression, female sex (odds ratio [OR]: 0.05, P = .002) was associated with reduced inpatient mortality. Advanced age (OR: 1.06, P < .001), postoperative transfusion (OR: 1.05, P = .043), increased Injury Severity Score (OR: 1.03, P = .039), postoperative stroke (OR: 9.09, P = .016), postoperative myocardial infarction (OR: 9.9, P = .017), and left subclavian coverage (OR: 2.7, P = .029) were associated with inpatient death. CONCLUSIONS Female sex is associated with lower odds of inpatient mortality after TEVAR for BTAI, independent of age, injury severity, BTAI grade, and postoperative complications. Further study of the influence of sex on postdischarge outcomes is needed.

Protocolized approach saves the limb in peripheral arterial injury: A decade experience. Chin J Traumatol 2022:S1008-1275(22)00140-7. [PMID: 36641321 DOI: 10.1016/j.cjtee.2022.12.010] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/13/2022] [Revised: 09/30/2022] [Accepted: 11/12/2022] [Indexed: 12/29/2022] Open
Abstract
PURPOSE Outcomes of peripheral arterial injury (PAI) depend on various factors, such as warm ischemia time and concomitant injuries. Suboptimal prehospital care may lead to delayed presentation, and a lack of dedicated trauma system may lead to poorer outcome. Also, there are few reports of these outcomes. The aim of this study was to review our experience of PAI management for more than a decade, and identify the predictors of limb loss in these patients. METHODS This is a retrospective analysis of prospectively maintained database of trauma admissions at a level I trauma center from January 2008 to December 2019. Patients with acute upper limb arterial injuries or lower limb arterial injuries at or above the level of popliteal artery were included. Association of limb loss with ischemia time, mechanism of injury and concomitant injuries was studied using multiple logistic regressions. Statistical analysis was performed using STATA version 15.0 (Stata Corp LLC, Texas). RESULTS Out of 716 patients with PAI, the majority (92%) were young males. Blunt trauma was the most common mechanism of injury. Median ischemia time was 4 h (interquartile range 2-7 h). Brachial artery (28%) was the most common injured vessel followed by popliteal artery (18%) and femoral artery (17%). Limb salvage rate was 78%. Out of them, 158 (22%) patients needed amputation, and 53 (7%) had undergone primary amputation. The majority (86%) of patients who required primary or secondary amputations had blunt trauma. On multivariate analysis, blunt trauma, ischemia time more than 6 h and concomitant venous, skeletal, and soft tissue injuries were associated with higher odds of amputation. CONCLUSION Over all limb salvage rates was 78% in our series. Blunt mechanism of injury and associated skeletal and soft tissue injury, ischemia time more than 6 h portend a poor prognosis. Injury prevention, robust prehospital care, and rapid referral to specialized trauma center are few efficient measures, which can decrease the morbidity associated with vascular injury.

Abstract
BACKGROUND Outcomes after vascular injuries in wartime are well documented, but studies on vascular injuries in a civilian European populations are scarce. METHODS A retrospective study on all adults admitted to a North-European level 1-trauma centre 2009-2018 with The Abbreviated Injury Scale-codes for non-iatrogenic vascular trauma (VT). Data were extracted from both national and regional trauma-registries, as well as patient charts. Patient demographics, mechanism, and location of vascular injury were registered as well as its treatment. Incidence and injury scores (ISS, NISS and TRISS) were calculated and overall survival (Kaplan-Meier) estimated. RESULTS Of 4042 trauma-patients, 68 (1.7%) (median age 44 years, 76% males) sustained 81 vascular injuries (69 arterial; 12 venous); 46 blunt and 22 (32%) penetrating injuries. The total incidence of vascular injuries was 1.45/100,000 inhabitants and did not change over the study-period (95% confidence interval 1.13-1.82). The injuries were located in thorax (n = 17), neck (n = 16) and abdominal region (n = 15); most of the blunt injuries followed traffic (n = 31) or falling accidents (n = 10), and with 17 of the 22 penetrating injuries due to stabbing. The median ISS and NISS-scores were 22 and 33, with 50 (74%) and 55 (81%) patients having scores > 15, respectively. Forty-three (63%) patients had open surgical repair and 8 (12%) received endovascular treatment. Twenty-one patients died within 30-days (31%), 33% and 27% after blunt and penetrating injuries, respectively. Half of the patients that died within 24 h sustained aortic injury. CONCLUSIONS Traumatic vascular injuries are rare in civilian settings and are less than 2% of major trauma admissions. These patients are often seriously injured and their treatment can be challenging with high 30-day mortality. TRIAL REGISTRATION Retrospectively registered.

Abstract
Penetrating vascular injury has become the topic of interest with increased gun violence in the United States. The radiologist plays a crucial role in establishing and systemizing the signs of vascular injury such as intimal flap, dissection, pseudoaneurysm, rupture, and arteriovenous fistula. Various imaging techniques such as ultrasound Doppler, computed tomographic angiography (CTA), magnetic resonance angiography, and conventional angiography are being employed based on clinical recommendations. Of all the techniques, CTA has been shown to embrace a promising role in identifying vascular injuries with superior sensitivity, specificity, and accuracy. An acquaintance of the imaging features has been shown to improve the approach to trauma patients in clinical settings. This article details the imaging modalities and the features of the head-and-neck penetrating vascular injury.

Abstract
BACKGROUND Injuries to the axillosubclavian arteries are rare, comprising 5% of all extremity trauma. This study aims to examine contemporary outcomes of traumatic axillosubclavian injuries. METHODS A retrospective review was performed on patients admitted with innominate, subclavian, and/or axillary artery injuries to a level 1 trauma center from 2011 to 2021. Patients undergoing endovascular repair were compared to those with open repair. RESULTS Thirty two patients met inclusion criteria. Injuries were approached open in 22 (59%) cases and endovascular in 10 (27%). There was no difference in 30-day mortality or hospital length of stay between endovascular and open repair. Endovascular repairs had shorter operative times (1.9 vs 3.1 h, p = 0.009) and lower blood loss (72 vs 1662 mL, p < 0.001). CONCLUSIONS Endovascular repair of axillosubclavian arterial injuries demonstrate similar outcomes to open repair. Significantly shorter operative times and lower blood loss suggest potential decreased morbidity.

Abstract
BACKGROUND Traumatic vascular injury in the extremities may be associated with a low mortality rate but can lead to limb loss that seriously affects patients' functionality. Multiple scoring systems have been designed to evaluate the prognosis, but none are 100% predictive. The management of traumatic vascular injury remains challenging and depends mostly on the surgeon's experience. OBJECTIVES We identified the risks associated with limb loss and further investigated the utility of current amputation indexes. METHODS We retrospectively reviewed 53 cases of traumatic vascular injury in the extremities at a tertiary referral medical center over the past ten years (January 2011-December 2020). The mangled extremity severity score (MESS), limb salvage index (LSI), and predictive salvage index (PSI) were used to assess the traumatized limbs. The injury characteristics and outcomes were evaluated using regression analysis. RESULTS The incidence of limb loss was 20.8% (n = 11), and open fractures were the most related factor. Extensive involvement of soft tissue, vascular injury combined with tibia or fibula fractures, initial shock status, and the amount of transfusion were associated with limb loss. CONCLUSIONS Our study identified the risk factors and clinical utility of MESS, PSI, and LSI. While both LSI and PSI had acceptable diagnostic accuracy, amputation should be decided based on a variety of criteria and clinical features. Salvaging any limb that has not become apparently futile seems logical, yet the presence of certain factors may suggest a worse outcome.

Abstract
BACKGROUND The aim of this study was to provide a description of vascular trauma and its management at trauma centers across Canada. METHODS This retrospective cohort study evaluated patients from 8 Canadian level 1 trauma centers (2011-2015). Medical records were queried to identify adult patients who survived to hospital with major vascular injury. Major vascular injury was defined as injury to named arterial or venous vessels in the legs, arms torso, and neck. Data collected included patient demographics, injury mechanism, injury details, management and clinical outcomes. RESULTS A total of 1330 patients were included. Patients were 76% male with a mean age of 43 (SD 18.8). Reported injuries were 63% blunt, 36% penetrating, and the remainder mixed. The most common specific mechanisms of injury were motor vehicle collision (36%), stabbing (26%), and falls (16%), with gunshot injuries accounting for <5%. Pre-hospital tourniquets were applied in 27 patients (2%). The mean Injury Severity Score (ISS) was 24 (SD 14.5). We identified injuries to named vessels of the neck (32%), thorax (23%), abdomen and pelvis (27%), upper extremity (14%) and lower extremity (10%). Specific vascular injuries included transection (50%), complete occlusion (11%), partial occlusion (39%), and pseudoaneurysm formation (11%). Injuries were managed non-operatively in 32%, with definitive open surgical management (24%), endovascular management (9%) and with damage control techniques in the operating room (3%). Amputation occurred in 10% of lower extremity and 5% of upper extremity injuries. Responsibility for vascular injury management was undertaken by a wide variety of specialists (n = 17). Overall, in-hospital mortality was 13%, and 2% of patients underwent amputation. CONCLUSION This study describes the nature and management of vascular injuries across Canada. The variability in injury mechanisms, management strategies, specialty responsible for management, and outcomes have important implications for practice change and knowledge translation.

Outcomes of thoracic endovascular aortic repair in patients with concomitant blunt thoracic aortic injury and traumatic brain injury from the Aortic Trauma Foundation global registry. J Vasc Surg 2021; 75:930-938.

Abstract
BACKGROUND Traumatic brain injury (TBI) and blunt thoracic aortic injury (BTAI) are the top two leading causes of death after blunt force trauma. Patients presenting with concomitant BTAI and TBI pose a specific challenge with respect to management strategy, because the optimal hemodynamic parameters are conflicting between the two pathologies. Early thoracic endovascular aortic repair (TEVAR) is often performed, even for minimal aortic injuries, to allow for the higher blood pressure parameters required for TBI management. However, the optimal timing of TEVAR for the treatment of BTAI in patients with concomitant TBI remains an active matter of controversy. METHODS The Aortic Trauma Foundation international prospective multicenter registry was used to identify all patients who had undergone TEVAR for BTAI in the setting of TBI from 2015 to 2020. The primary outcomes included delayed ischemic or hemorrhagic stroke, in-hospital mortality, and aortic-related mortality. The outcomes were examined among patients who had undergone TEVAR at emergent (<6 vs ≥6 hours) or urgent (<24 vs ≥24 hours) intervals. RESULTS A total of 100 patients (median age, 43 years; 79% men; median injury severity score, 41) with BTAI (Society for Vascular Surgery BTAI grade 1, 3%; grade 2, 10%; grade 3, 78%; grade 4, 9%) and concomitant TBI who had undergone TEVAR were identified. Emergent repair was performed for 51 patients (51%). Comparing emergent repair (<6 hours) to urgent repair (≥6 hours), no difference was found in delayed cerebral ischemic events (2.0% vs 4.1%; P = .614), in-hospital mortality (15.7% vs 22.4%; P = .389), or aortic-related mortality (2.0% vs 2.0%; P = .996) and no patient had experienced delayed hemorrhagic stroke. Likewise, repairs conducted in an urgent (<24 hours) setting showed no differences compared with those completed in an emergent (≥24 hours) setting regarding delayed ischemic stroke (2.6% vs 4.3%; P = .548), in-hospital mortality (18.2% vs 21.7%; P = .764), or aortic-related mortality (1.3% vs 4.3%; P = .654), and no patient had experienced delayed hemorrhagic stroke. CONCLUSIONS In contrast to prior retrospective efforts, results from the Aortic Trauma Foundation international prospective multicenter registry have demonstrated that neither emergent nor urgent TEVAR for patients with concomitant BTAI and TBI was associated with delayed stroke, in-hospital mortality, or aortic-related mortality. In these patients, the timing of TEVAR did not have an effect on the outcomes. Therefore, the decision to intervene should be guided by individual patient factors rather than surgical timing.

Abstract
Penetrating injuries to the subclavian artery carry a high mortality rate, especially when the patient presents in shock. Rapid and effective haemorrhage control is challenging due to the anatomical location at the thoracic outlet. Historically, vessel ligation has been used to control bleeding, but this is often performed late, when metabolic exhaustion is established, and is associated with upper-limb ischaemia and limb loss. Rapid proximal control through the chest with temporary intravascular shunting is the damage control technique of choice to temporise blood loss and restore perfusion until the patient is physiologically optimised for a delayed definitive vascular repair. We describe a case of vascular damage control in a patient after gunshot wound.

Abstract
INTRODUCTION Visceral artery injuries are rare but lethal entities that pose significant management challenges in a patient who presents with blunt trauma. There is a paucity of specific guidelines both in the trauma and vascular literature regarding the management of blunt intra-abdominal vascular injuries. The midterm outcomes of two cases of blunt traumatic visceral artery injuries managed successfully with endovascular interventions are presented. REPORT An 18 year old male victim of a motor vehicle accident was found to have infrarenal aortic, coeliac artery (CA), and superior mesenteric artery (SMA) injuries. The second patient was a 15 year old male who presented with traumatic occlusion of the CA after an all terrain vehicle collision. Both patients had other associated abdominal and bony injuries. All vascular injuries were addressed endovascularly, which was followed by repair of other associated injuries. In the first case, a self expanding non-covered nitinol stent was used in the injured but tortuous CA; for repair of the SMA, a covered balloon expandable stent was used. In the second patient, a balloon expandable non-covered stent was used to repair the CA occlusion. In both cases, the 12 month post-operative follow up showed that all stents were patent and the patients were asymptomatic. DISCUSSION Endovascular repair of the mesenteric arteries following traumatic injury can be achieved safely, with good midterm outcomes. More data are needed to define the indications for and long term safety and patency of stents used in traumatic visceral artery injuries.

Abstract
OBJECTIVE Traumatic popliteal artery injuries are associated with the greatest risk of limb loss of all peripheral vascular injuries, with amputation rates of 10% to 15%. The purpose of the present study was to examine the outcomes of patients who had undergone operative repair for traumatic popliteal arterial injuries and identify the factors independently associated with limb loss. METHODS A multi-institutional retrospective review of all patients with traumatic popliteal artery injuries from 2007 to 2018 was performed. All the patients who had undergone operative repair of popliteal arterial injuries were included in the present analysis. The patients who had required a major lower extremity amputation (transtibial or transfemoral) were compared with those with successful limb salvage at the last follow-up. The significant predictors (P < .05) for amputation on univariate analysis were included in a multivariable analysis. RESULTS A total of 302 patients from 11 institutions were included in the present analysis. The median age was 32 years (interquartile range, 21-40 years), and 79% were men. The median follow-up was 72 days (interquartile range, 20-366 days). The overall major amputation rate was 13%. Primary repair had been performed in 17% of patients, patch repair in 2%, and interposition or bypass in 81%. One patient had undergone endovascular repair with stenting. The overall 1-year primary patency was 89%. Of the patients who had lost primary patency, 46% ultimately required major amputation. Early loss (within 30 days postoperatively) of primary patency was five times more frequent for the patients who had subsequently required amputation. On multivariate regression, the significant perioperative factors independently associated with major amputation included the initial POPSAVEIT (popliteal scoring assessment for vascular extremity injury in trauma) score, loss of primary patency, absence of detectable immediate postoperative pedal Doppler signals, and lack of postoperative antiplatelet therapy. Concomitant popliteal vein injury, popliteal injury location (P1, P2, P3), injury severity score, and tibial vs popliteal distal bypass target were not independently associated with amputation. CONCLUSIONS Traumatic popliteal artery injuries are associated with a significant rate of major amputation. The preoperative POPSAVEIT score remained independently associated with amputation after including the perioperative factors. The lack of postoperative pedal Doppler signals and loss of primary patency were highly associated with major amputation. The use of postoperative antiplatelet therapy was inversely associated with amputation, perhaps indicating a protective effect.

Popliteal scoring assessment for vascular extremity injuries in trauma study. J Vasc Surg 2021; 74:804-813.e3. [PMID: 33639233 DOI: 10.1016/j.jvs.2021.02.015] [Citation(s) in RCA: 10] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/30/2020] [Accepted: 02/06/2021] [Indexed: 12/15/2022]
Abstract
OBJECTIVE Traumatic popliteal vascular injuries are associated with the highest risk of limb loss of all peripheral vascular injuries. A method to evaluate the predictors of amputation is needed because previous scores could not be validated. In the present study, we aimed to provide a simplified scoring system (POPSAVEIT [popliteal scoring assessment for vascular extremity injuries in trauma]) that could be used preoperatively to risk stratify patients with traumatic popliteal vascular injuries for amputation. METHODS A review of patients sustaining traumatic popliteal artery injuries was performed. Patients requiring amputation were compared with those with limb salvage at the last follow-up. Of these patients, 80% were randomly assigned to a training group for score generation and 20% to a testing group for validation. Significant predictors of amputation (P < .1) on univariate analysis were included in a multivariable analysis. Those with P < .05 on multivariable analysis were assigned points according to the relative value of their odds ratios (ORs). Receiver operating characteristic curves were generated to determine low- vs high-risk scores. An area under the curve of >0.65 was considered adequate for validation. RESULTS A total of 355 patients were included, with an overall amputation rate of 16%. On multivariate regression analysis, the risk factors independently associated with amputation in the final model were as follows: systolic blood pressure <90 mm Hg (OR, 3.2; P = .027; 1 point), associated orthopedic injury (OR, 4.9; P = .014; 2 points), and a lack of preoperative pedal Doppler signals (OR, 5.5; P = .002; 2 points [or 1 point for a lack of palpable pedal pulses if Doppler signal data were unavailable]). A score of ≥3 was found to maximize the sensitivity (85%) and specificity (49%) for a high risk of amputation. The receiver operating characteristic curve for the validation group had an area under the curve of 0.750, meeting the threshold for score validation. CONCLUSIONS The POPSAVEIT score provides a simple and practical method to effectively stratify patients preoperatively into low- and high-risk major amputation categories.

Intraoperative heparin use is associated with reduced mortality without increasing hemorrhagic complications after thoracic endovascular aortic repair for blunt aortic injury. J Vasc Surg 2020; 74:71-78. [PMID: 33348003 DOI: 10.1016/j.jvs.2020.12.068] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/16/2020] [Accepted: 12/05/2020] [Indexed: 11/17/2022]
Abstract
OBJECTIVE Thoracic endovascular aortic repair (TEVAR) is an effective treatment of blunt thoracic aortic injury (BTAI). However, the risks and benefits of administering intraoperative heparin in trauma patients are not well-defined, especially with regard to bleeding complications. METHODS The Vascular Quality Initiative registry was queried from 2013 to 2019 to identify patients who had undergone TEVAR for BTAI with or without the administration of intraoperative heparin. Univariate analyses were performed with the Student t test, Fisher exact test, or χ2 test, as appropriate. Multivariable logistic regression was then performed to assess the association of heparin with inpatient mortality. RESULTS A total of 655 patients were included, of whom most had presented with grade III (53.3%) or IV (20%) BTAI. Patients receiving heparin were less likely to have an injury severity score (ISS) of ≥15 (70.2% vs 90.5%; P < .0001) or major head or neck injury (39.6% vs 62.9%; P < .0001). Patients receiving heparin also had a lower incidence of inpatient death (5.1% vs 12.9%; P < .01). Across all injury grades, heparin use was not associated with the need for intraoperative transfusion or postoperative transfusion or the development of hematoma. In patients with grade III BTAI, the nonuse of heparin was associated with an increased risk of lower extremity embolization events (7.4% vs 1.8%; P < .05). On multivariable logistic regression analysis for inpatient mortality, intraoperative heparin use (odds ratio [OR], 0.31; 95% confidence interval [CI], 0.11-0.86; P < .05) and female gender (OR, 0.11; 95% CI, 0.11-0.86; P < .05) were associated with better survival, even after controlling for head and neck trauma and injury grade. In contrast, increased age (OR, 1.06; 95% CI, 1.03-1.1; P < .001), postoperative transfusion (OR, 1.06; 95% CI, 1.02-1.11; P < .01), higher ISS (OR, 1.04; 95% CI, 1.01-1.07; P < .05), postoperative dysrhythmia (OR, 4.48; 95% CI, 1.10-18.18; P < .05), and postoperative stroke or transient ischemic attack (OR, 5.54; 95% CI, 1.11-27.67; P < .05) were associated with increased odds of inpatient mortality. CONCLUSIONS Intraoperative heparin use was associated with reduced inpatient mortality for patients undergoing TEVAR for BTAI, including those with major head or neck trauma and high ISSs. Heparin use did not increase the risk of hemorrhagic complications across all injury grades. Also, in patients with grade III BTAI, heparin use was associated with a reduced risk of lower extremity embolic events. Heparin appears to be safe during TEVAR for BTAI and should be administered when no specific contraindication exists.

Abstract
Management of pediatric iatrogenic arterial occlusions can be challenging clinically, leading to chronic complications such as claudication and limb length discrepancy. We report the case of a 6-month-old female patient who had experienced iatrogenic right external iliac and common femoral arterial occlusion. At the age of 8 years, she had developed claudication and a limb length discrepancy of 3.2 cm. She underwent common iliac artery to superficial femoral artery and profunda artery bypass via a branched autologous reverse great saphenous vein using microsurgical techniques for the distal anastomoses. In the present report, we have focused on the musculoskeletal improvements, benefits of microsurgery in pediatric vessels, and maximization of epiphyseal perfusion.

Abstract
PURPOSE To compare outcomes between open (OR) and endovascular repair following superficial femoral artery (SFA) injuries. METHODS This is a cross-sectional study querying the 2012-2014 National Inpatient Sample for SFA injuries. Patients were grouped into OR and stent-graft placement (SGP). Primary outcome was in-hospital mortality. Secondary outcomes included hospital length of stay (HLOS), fasciotomy and amputation rate, and cost. Wilcoxon rank-sum, Kruskal-Wallis, Chi-squared test with Bonferroni adjustment were used as appropriate; p < 0.05 was significant. RESULTS 255 Patients were identified. Mean age was 34.6 years and majority were males. OR was performed in 82.7%. Overall mortality rate was 3.7%. Median HLOS was 8 days. Fasciotomies were performed in 31% and lower limb amputations in 3.7%. Males more often underwent OR (89.0% vs. 73.1%, p < 0.01). SGP patients were significantly older (44.9 vs. 32.5 years; p < 0.01), and with Medicare insurance (20.5% vs. 6.5%; p < 0.01. Mortality, HLOS, and hospitalization cost were not significantly different. OR patients had higher rate of fasciotomy (35.4% vs. 15.4%; p < 0.01). CONCLUSIONS Endovascular management is not inferior to OR following SFA injuries and both carry a low amputation rate. OR is associated with a higher fasciotomy rate. Endovascular repair should be considered when technically feasible.

Abstract
Current knowledge of blunt cerebrovascular injuries (BCVIs) in craniomaxillofacial fracture (CMF) patients is limited. The purpose of this study was to determine the occurrence of BCVIs in patients with all types of CMF. This retrospective study included CMF patients in a level 1 trauma centre during a 3-year period. Patients who were not imaged with computed tomography angiography and patients with mechanisms other than blunt injury were excluded. The primary outcome variable was BCVI. A total of 753 patients were included in the analysis. A BCVI was detected in 4.4% of the patients screened. BCVIs occurred in 8.7% of cranial fracture patients, 7.1% of combined craniofacial fracture patients, and 3.1% of facial fracture patients. The risk of BCVI was significantly increased in patients with isolated cranial fractures (odds ratio (OR) 2.55, 95% confidence interval (CI) 1.18-5.50; P=0.017), those involved in motor vehicle accidents (OR 3.42, 95% CI 1.63-7.17; P=0.001), and those sustaining high-energy injuries (OR 3.17, 95% CI 1.57-6.40; P=0.001). BCVIs in CMF patients are relatively common in high-energy injuries. However, these injuries also occur in minor traumas. Imaging thresholds should be kept low in this patient population when BCVIs are suspected.

Temporary intravascular shunt use improves early limb salvage after extremity vascular injury. J Vasc Surg 2020; 73:1304-1313. [PMID: 32987146 DOI: 10.1016/j.jvs.2020.08.137] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/20/2020] [Accepted: 08/17/2020] [Indexed: 10/23/2022]
Abstract
OBJECTIVE The use of temporary intravascular shunts (TIVSs) allow for restoration of distal perfusion and reduce ischemic time in the setting of arterial injury. As a damage control method, adjunct shunts restore perfusion during treatment of life-threatening injuries, or when patients require evacuation to a higher level of care. Single-center reports and case series have demonstrate that TIVS use can extend the opportunity for limb salvage. However, few multi-institutional studies on the topic have been reported. The objective of the present study was to characterize TIVS use through a multi-institutional registry and define its effects on early limb salvage. METHODS Data from the Prospective Observation Vascular Injury Treatment registry was analyzed. Civilian patients aged ≥18 years who had sustained an extremity vascular injury from September 2012 to November 2018 were included. Patients who had a TIVS used in the management of vascular injury were included in the TIVS group and those who had received treatment without a TIVS served as the control group. An unadjusted comparison of the groups was conducted to evaluate the differences in the baseline and outcome characteristics. Double robust estimation combining logistic regression with propensity score matching was used to evaluate the effect of TIVS usage on the primary end point of limb salvage. RESULTS TIVS use was identified in 78 patients from 24 trauma centers. The control group included 613 patients. Unmatched analysis demonstrated that the TIVS group was more severely injured (mean ± standard deviation injury severity score, 18.83 ± 11.76 for TIVS vs 14.93 ± 10.46 for control; P = .002) and had more severely mangled extremities (mean ± standard deviation abbreviated injury scale, extremity, score 3.23 ± 0.80 for TIVS vs 2.95 ± 0.87 for control; P = .008). Logistic regression demonstrated that propensity-matched control patients had a three times greater likelihood of amputation compared with the TIVS patients (odds ratio, 3.6; 95% confidence interval, 1.2-11.1; P = .026). Concomitant nerve injury and orthopedic fracture were associated with a greater risk of amputation. The median follow-up for the TIVS group was 12 days (interquartile range, 4-25 days) compared with 9 days (interquartile range, 4-18 days) for the control group. CONCLUSIONS To the best of our knowledge, the present study is the first multicenter, matched-cohort study to characterize early limb salvage as a function of TIVS use in the setting of extremity vascular injury. Shunts expedite limb perfusion and resulted in lower rates of amputation during the early phase of care. The use of TIVS should be one part of a more aggressive approach to restore perfusion in the most injured patients and ischemic limbs.

Improved outcomes of endovascular repair of thoracic aortic injuries at higher volume institutions. J Vasc Surg 2020; 73:1314-1319.

Abstract
BACKGROUND The use of thoracic endovascular aortic repair (TEVAR) has significantly improved the ability to treat traumatic aortic injuries (tTEVAR). We sought to determine whether a greater center volume correlated with better outcomes. METHODS Vascular Quality Initiative data of TEVAR (2011-2017) for trauma were used in the present analysis. Using the distribution of the annual case volume at the participating centers, the sample was stratified into three terciles. In-hospital mortality at high-volume centers (HVCs) and low-volume centers (LVCs) was compared after adjustment for risk factors established in our previous Vascular Quality Initiative-based risk model containing age, gender, renal impairment, left subclavian artery involvement, and select concomitant injuries. RESULTS A total of 619 tTEVAR cases were studied across 74 centers. HVCs (n = 184 cases) had performed ≥4.9 cases annually and LVCs (n = 220 cases) had performed ≤2.4 cases annually. Both crude mortality (4.4% vs 8.6%; P = .22) and adjusted odds of mortality (odds ratio, 0.44; 95% confidence interval, 0.18-1.09; P = .08) showed a trend toward better outcomes for tTEVAR performed at HVCs than at LVCs. The addition of center volume to our previous multivariate model significantly improved its discriminative ability (C-statistic, 0.90 vs 0.88; P = .02). The overall TEVAR volume (for all indications) was not associated with increased odds of mortality for tTEVAR (odds ratio, 0.46; 95% confidence interval, 0.17-1.20; P = .11), nor did it improve the model's discriminative ability. CONCLUSIONS Higher volume centers showed improved perioperative mortality after tTEVAR. The thoracic aortic trauma volume was more predictive than the overall TEVAR volume, suggesting that technical expertise is not the driving factor. Stable patients might benefit from transfer to a higher volume center before repair.

Abstract
Decannulation from pediatric veno-arterial extracorporeal membrane oxygenation (VA-ECMO) involves the removal of large arterial perfusion cannulas from relatively small lower extremity arteries. While these challenging repairs are frequently performed by general pediatric surgeons, there is little standardization with regard to vascular techniques within the pediatric surgery training paradigm, resulting in variability in the repair of these arteriotomies and potential future consequences for lower extremity perfusion and growth. Herein we present a technique for repair of large common femoral arteriotomies following removal of ECMO perfusion cannulas utilizing a dual-layer patch of ipsilateral saphenous vein harvested via the arterial cutdown incision. This vein segment is everted to maximize endothelial surface area of the patch and dual layered to provide additional support against aneurysmal degeneration. The described technique is an effective repair of arteriotomy following VA-ECMO decannulation, which minimizes vascular complications and is an accessible technique to those without advanced vascular surgical training. LEVEL OF EVIDENCE: Level IV; operative technique description with small case series.

Abstract
Blunt traumatic transection of the innominate artery is rare. We describe a case of a 36-year-old male who presented to our Emergency & Trauma Center after being struck by a motor vehicle at high speed. Computerised Tomography (CT) scanning after the patient was stabilised facilitated the prompt diagnosis of the injury. The patient underwent open repair by midline sternotomy, with debranching of the innominate artery, using hypothermic circulatory arrest as a neuroprotective measure. The patient was successfully extubated on post-operative day 3, without neurological deficit. We provide our experience as an option for treating any patient that presents with such an injury.

Abstract
BACKGROUND The purpose of this study was to evaluate the epidemiology and management of pediatric vascular extremity trauma to assess injury patterns and other factors that may contribute to poor outcomes. METHODS Using the California Office of Statewide Health Planning and Development discharge database, we identified pediatric patients with extremity arterial trauma admitted to acute-care hospitals from 2007 to 2014. Demographics, management patterns, and outcomes were collected and analyzed. RESULTS A total of 775 patients were treated for an extremity arterial injury. Overall, 40% were admitted to pediatric trauma centers and 39% to adult trauma centers. Management was predominantly by open surgical repair. Injury to the common femoral artery was associated with mortality (Hazard Ratio 3.9; 95% CI 1.1-14.5; p < 0.05). Popliteal artery injuries (Odds Ratio [OR] 4.8; 95% CI 1.2-19.9; p < 0.05) and anterior tibial artery injuries (OR 7.1; 95% CI 1.4-37.3; p < 0.05) had an increased risk of amputation. There was no difference in amputation or mortality rates by hospital category. CONCLUSIONS Pediatric extremity arterial injuries are rare. In California, outcomes are similar by hospital type. Common femoral artery injuries are associated with an increased risk of mortality, while popliteal and anterior tibial artery injuries are associated with an increased risk of amputation.

Abstract
Background: Morbidity, lesion pattern, management and short-term outcomes of civilian vascular trauma are rarely evaluated. Therefore, analysis of in hospital results in patients with non-iatrogenic vascular trauma in a tertiary referral hospital was performed. Patients and methods: Retrospective evaluation of patients with vascular trauma from 2007-2017 was done. 48 patients (34 male, 14 females, mean age 56 years) were included. Excluded were patients with iatrogenic vascular complications. Major cause of vascular trauma were traffic accidents in 43.8 %, fall from great heights in 27.1 %, sport and home related injuries in 16.8 %, suicidal injuries in 4.2 % and gunshot wounds in 2.1 % (other 6.3 %). 60.4 % of patients presented with blunt, 39.6 % of patients with penetrating vascular trauma. More than half of the cases included polytraumatized patients (54.4 %). Results: Most commonly affected were the popliteal (25.0 %) and the axillar artery (18.8 %). Aortic injuries were present in 14.6 % of cases, whereas the femoral and subclavian artery were involved in 12.6 % and 10.4 %. Vascular reconstruction was performed by interposition graft in 45.9 %, direct suture in 18.8 %, patchplasty in 10.4 %, ligation in 12.4 %, and implantation of stentgraft in 12.5 %. Postoperative complication rate was 54.2 %. Rate of in-hospital major amputation was 14.6 % and in-hospital mortality was 14.6 % as well. Comparison between blunt and penetrating trauma as to postoperative complication (p = 0.322), blood transfusion (p = 0.452) and amputation (p = 0.304) showed no significant differences, whereas lethality in blunt trauma was 20.6 % vs. 5.2 % in penetrating trauma. Injury severity score (ISS) was significantly elevated for blunt trauma patients (mean ISS Score blunt 32 vs 21 penetrating, p = 0.043). Conclusions: The majority of vascular lesions is caused by blunt trauma. Blunt lesions do also show a severe injury pattern, compared to penetrating trauma, and the complication rate remains high. However, by means of vascular reconstruction, limb salvage is feasible in a high percentage of cases.

Direct site endovascular repair as salvage procedure after anastomotic breakdown of primary repair following trauma. JOURNAL OF VASCULAR SURGERY CASES INNOVATIONS AND TECHNIQUES 2019; 5:597-601. [PMID: 31872165 PMCID: PMC6908996 DOI: 10.1016/j.jvscit.2019.04.002] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 12/17/2018] [Accepted: 04/02/2019] [Indexed: 11/22/2022]
Abstract
A 16-year-old boy presented to a level I trauma center after multiple gun shot wounds and a motorcycle crash. He was in profound hemorrhagic shock and had multiple traumatic injuries, including a right common iliac arterial injury. The vessel was shunted for damage control and subsequently repaired primarily. On hospital day 18, he experienced dehiscence of the anastomosis requiring urgent surgery. The artery was ultimately repaired with an expandable polytetrafluoroethylene stent graft deployed in an open fashion through the site of injury. We discuss the use of stent grafts as an interesting alternative to suture repair after anastomotic disruption.

An analysis of the vascular injuries and attempted resuscitation surrounding the assassination of Martin Luther King Jr. J Vasc Surg 2019; 70:1652-1657. [PMID: 31653379 DOI: 10.1016/j.jvs.2019.06.203] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/25/2019] [Accepted: 06/30/2019] [Indexed: 11/28/2022]
Abstract
Martin Luther King Jr was the most prominent civil rights leader in the United States in the 1960s. He was shot by an assassin in Memphis, Tennessee, on April 4, 1968. After the shooting he was taken to a local hospital where he had an unsuccessful resuscitation for a right subclavian artery transection. Despite the fact that the circumstances around the assassination have been frequently reported and reviewed in the past 50 years, the specific vascular care of the traumatic injury has not been analyzed. This paper reviews the medical aspects of the King assassination and the management of his subclavian injury.

Abstract
BACKGROUND Due to the increasing threat of terrorist attacks and assassinations even in Europe, the interest in management of severe vascular injuries, which, with an increased incidence of 10% are to be expected with such penetrating wounds, is also growing; however, with increasing subspecialization in surgery there is a threat that the know-how in vascular surgery will become lost among non-vascular surgical specialists. Therefore, the Germany military established an educational program, the so-called DUOplus concept, to ensure that future military surgeons acquire and retain the experience and skills to fulfill the demanding role of a deployed surgeon. OBJECTIVE The DUOplus concept of the German Medical Forces is introduced with a special focus on vascular surgery training. RESULTS All trainee German military surgeons attain a second specialization alongside general surgery. This residency includes several courses in various surgical specialties as well as a 12-month rotation in a vascular surgery department. The core elements of vascular trauma training are two practical courses on life-like models. In these courses, which were developed especially for the needs of non-vascular surgeons in hands-on training, open surgical techniques and damage control measures including resuscitative endovascular balloon occlusion of the aorta (REBOA) are taught on suitable models and intensively practiced. CONCLUSION All surgeons potentially confronted with traumatic and iatrogenic vascular injuries should have some basic competence in the management of vascular trauma. Especially the courses in vascular surgery for non-vascular surgeons offer such a skill set for every surgeon. Next to the German military surgeons, the courses are attended more and more by civilian and military surgeons from different surgical specialties and nationalities.

Hybrid approach to complex vascular injury secondary to blast induced scapulothoracic dissociation. Trauma Case Rep 2019; 23:100236. [PMID: 31453310 PMCID: PMC6702402 DOI: 10.1016/j.tcr.2019.100236] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 07/21/2019] [Indexed: 11/27/2022] Open
Abstract
Scapulothoracic dissociation is a rare but devastating injury complex involving high velocity blunt trauma to the osseous, muscular, neurologic, and vascular structures of the shoulder girdle. Often seen following a motor vehicle or motorcycle accident, this injury complex presents with vascular trauma in over 80% of cases. We present a unique case of scapulothoracic dissociation secondary to a self-inflicted shotgun wound to the shoulder, not previously reported in the literature. The patient presented in hemorrhagic shock, with an open wound to the chest, and a flaccid, pulseless left upper extremity. Imaging was consistent with subclavian artery transection with thrombosis. He underwent successful upper extremity revascularization with a hybrid approach including open wound exploration and endovascular repair of the subclavian artery. Furthermore, we review the diagnosis and treatment of scapulothoracic dissociation and discuss the safety of emerging hybrid vascular techniques in the management of subclavian and axillary vessel trauma.

Preclinical evaluation of the atraumatic nature of a spring loaded blunt tip coaxial needle in a swine model. Diagn Interv Imaging 2019; 100:813-820. [PMID: 31378512 DOI: 10.1016/j.diii.2019.07.003] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/25/2019] [Revised: 06/19/2019] [Accepted: 07/03/2019] [Indexed: 11/29/2022]
Abstract
PURPOSE To test in vivo in an animal model the inherent atraumatic characteristics of the spring loaded blunt tip of a coaxial needle (Gangi-SoftGuard®, Apriomed, Sweden) against a conventional sharp stylet coaxial needle. MATERIAL AND METHODS The study was conducted on a 40kg male swine that was its own control for a vascular trauma model. The procedure consisted of voluntary attempts to transfix and traverse the artery/aorta under continuous real-time angiogram. Test and control needles were positioned in the region of the intercostal, superior mesenteric and femoral/deep femoral arteries, and in the aorta. Computed tomography (CT) angiogram was performed post trauma to check for bleeding in the form of extravasation of contrast material. One attempt was performed per site and needle, except for the intercostal artery where a second attempt was done with the test needle, resulting in a total of 4 and 5 tests for the control and test needles, respectively. RESULTS With the spring loaded blunt tip, no vascular trauma or bleeding was noted in the intercostal, superior mesenteric and femoral arteries, nor in the aorta. Vascular spasm that recovered with time was noted during the second attempt to transfix the same intercostal artery. There were consistent vascular traumas and bleedings with the control needle in all three tested arteries and the aorta, confirmed on angiogram as well as CT angiogram. CONCLUSION The atraumatic feature offered by the spring loaded blunt tip prevented vascular trauma during the 5 attempts made to transfix the artery/aorta in a swine.

Implementation and results of a practical grading system for blunt thoracic aortic injury. J Vasc Surg 2019; 70:1082-1088. [PMID: 30922749 DOI: 10.1016/j.jvs.2019.01.048] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/07/2018] [Accepted: 01/31/2019] [Indexed: 11/24/2022]
Abstract
OBJECTIVE We previously proposed a grading system for blunt thoracic aortic injury (BTAI) designed to guide therapy. This study analyzed our outcomes since implementing this system. METHODS A single-center, retrospective study was conducted of consecutive patients presenting with BTAI between January 2014 and December 2017. This grading system classified injuries into minimal, moderate, or severe on the basis of computed tomography imaging. Primary end points included timing of operation and mortality. Secondary end points included associated injuries, aortic anatomy, and operative details as well as 30-day follow-up. RESULTS During the study period, 87 patients with BTAI were identified. The majority of patients had a moderate injury occurring just distal to the left subclavian artery (LSA); 59 patients underwent thoracic endovascular aortic repair (TEVAR), whereas none of the patients with minimal injury (n = 24) required surgical treatment. The mean time to repair was 53 hours (1-191 hours) for moderate injury and 3.6 hours (0-7 hours) for severe injury. The average diameter and length of the endograft was 26 mm and 112 cm, respectively, and the LSA was covered in 42% of patients. Intravascular ultrasound to confirm sizing was used in 83% of cases. Most patients (92%) received intravenous heparin during TEVAR; the remainder received only heparin sheath flush because of concern for intracranial hemorrhage. None of the patients underwent LSA revascularization or developed stroke or spinal cord ischemia as a result of the procedure. Operative complications were seen in 6% of patients and included 1 femoral pseudoaneurysm, 1 lower extremity compartment syndrome, 1 type II endoleak requiring LSA embolization, and 1 intracranial bleed. The 30-day mortality was 7% (one aorta-related death). On 30-day postoperative follow-up, computed tomography imaging uniformly revealed positive aortic remodeling, and no secondary aortic intervention was required. CONCLUSIONS Institutional implementation of our grading system has streamlined treatment of BTAI, and our results confirm the following: patients with minimal injury do not require surgical treatment; patients with moderate injury can safely undergo TEVAR in a semielective manner once they are stable from other injuries; and patients with severe injury require emergent repair. These procedures are expeditious and can be successfully performed percutaneously with a single endograft. Complications are rare, and follow-up reveals excellent remodeling of the aorta, likely resulting in lengthened interval surveillance requirements for these patients.

Oesophageal perforation: an unexpected complication during extraction of a pacing lead. A case report. EUROPEAN HEART JOURNAL-CASE REPORTS 2019; 3:ytz008. [PMID: 31020253 PMCID: PMC6439371 DOI: 10.1093/ehjcr/ytz008] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 02/19/2018] [Accepted: 01/20/2019] [Indexed: 12/03/2022]
Abstract
Background Peri-procedural transoesophageal echocardiography (TOE) is important in monitoring and minimizing major complications during pacing lead extraction. It is a widely accepted precautionary measure, especially in extractions considered to be higher risk. Pacing lead extraction may be challenging, and it is associated with significant risk of major bleeding from vascular trauma. Case summary We present a case of an 87-year-old woman who had an extraction of a ventricular pacing lead that had perforated to an extra-cardiac location, most likely to the left pleural space. Peri-procedural TOE was used as a precaution. The entire pacing lead was successfully extracted with gentle traction using standard equipment (mechanical technique). Extraction was followed by development of pneumomediastinum and a left pleural effusion, initially attributed to pulmonary injury from the pacing lead but which proved to be related to oesophageal injury from the TOE. Discussion Transoesophageal echocardiography-related complications are uncommon but should be considered in cases of unexpected post-procedural deterioration. Clinical deterioration after a seemingly uneventful procedure should prompt a thorough case review. A systematic approach should be applied to identify the offending cause and enable corrective measures to be undertaken. This case report is an important reminder to all operators utilizing TOE for peri-procedural purposes that this precautionary measure itself also independently exposes the patient to additional risk.

The ability of magnetic resonance black blood vessel wall imaging to evaluate blunt cerebrovascular injury following acute trauma. J Neuroradiol 2019; 47:210-215. [PMID: 30677426 DOI: 10.1016/j.neurad.2019.01.091] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/03/2018] [Revised: 11/28/2018] [Accepted: 01/14/2019] [Indexed: 11/19/2022]
Abstract
BACKGROUND AND PURPOSE Blunt cerebrovascular injury (BCVI) is associated with a significant risk of ischemic stroke when left untreated. Cross-sectional imaging is vital to early BCVI diagnosis and treatment; however, conventional luminal vessel imaging is limited in its ability to evaluate for vessel wall pathology. The purpose of this study is to evaluate the ability of vessel wall magnetic resonance imaging (VWI) to detect and evaluate BCVI in acutely injured trauma patients relative to neck computed tomographic angiography (CTA). MATERIALS AND METHODS Trauma patients with suspected BCVI on initial neck CTA were prospectively recruited for VWI evaluation. Two neuroradiologists blinded to patient clinical history and CTA findings evaluated each artery independently on VWI and noted the presence and grade of BCVI. These results were subsequently compared to neck CTA findings relative to expert clinical consensus review. Interrater reliability of VWI for detecting BCVI was evaluated using a weighted Cohen κ-statistic. RESULTS Ten trauma patients (40 cervical arteries) were prospectively evaluated using both CTA and VWI. Out of 18 vascular lesions identified as suspicious for BCVI on CTA, six lesions were determined to represent true BCVI by expert consensus review. There was almost perfect agreement between VWI and expert consensus regarding the presence and grade of BCVI (κ=0.82). This agreement increased when considering only low grade BCVI. There was only fair agreement between CTA and expert clinical consensus (κ=0.36). This agreement decreased when considering only low grade BCVI. CONCLUSIONS VWI can potentially accurately identify and evaluate BCVI in acutely injured trauma patients with excellent inter-rater reliability.

Influence of luminal stenosis in aneurysmal and non-aneurysmal blunt cerebrovascular injury. Injury 2019; 50:131-136. [PMID: 30458982 DOI: 10.1016/j.injury.2018.11.003] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/23/2018] [Revised: 10/16/2018] [Accepted: 11/02/2018] [Indexed: 02/02/2023]
Abstract
BACKGROUND Current blunt cerebrovascular injury (BCVI) grading grossly differentiates injury characteristics such as luminal stenosis (LS) and aneurysmal disease. The effect of increasing degree of LS beyond the current BCVI grading scale on stroke formation is unknown. STUDY DESIGN BCVI over a 3-year period were retrospectively reviewed. To investigate influence of LS beyond the BCVI grading scale within aneurysmal and non-aneurysmal BCVI, grade 2 BCVI were subdivided into BCVI with ≥ 25% and ≤ 50% LS and BCVI with > 50% and ≤ 99% LS. Grade 3 BCVI were subdivided into BCVI with pseudoaneurysm (PSA) without LS and BCVI with PSA and LS. We hypothesized increased LS beyond the current BCVI grade distinctions would be associated with higher rates of stroke formation. RESULTS 312 BCVI were included, of which 140 were carotid BCVI and 172 vertebral BCVI. Sixteen carotid BCVI underwent endovascular intervention (EI) and 19 suffered a stroke. In carotid BCVI stroke rates increased sequentially with BCVI grade except in grade 3. There was a stroke rate of 12% in grade 1 carotid BCVI, 18% in grade 2, 6% in grade 3, and 31% in grade 4. In subgroup analysis for grade 2 carotid BCVI, BCVI with > 50% and ≤ 99% LS had higher rates of stroke (22% vs. 15%, p = 0.44) than BCVI with ≥ 25% and ≤ 50% LS. In subgroup analysis of grade 3 carotid BCVI, BCVI with PSA and LS had higher rates of stroke (9% vs. 4%, p = 0.48) than BCVI with PSA without LS. Higher rates of EI in grade 2 carotid BCVI with > 50% and ≤ 99% LS (22% vs. 5%, p = 0.14) and grade 3 carotid BCVI with PSA and LS (35% vs. 4%, p = 0.01) were noted in subgroup analysis. CONCLUSION Higher percentage LS beyond the currently used BCVI grading scale has a non-significantly increased rate of stroke in both aneurysmal and non-aneurysmal BCVI. Grade 3 BCVI with PSA and LS seems to be a high-risk subgroup. Use of EI confounds modern measurement of stroke risk in higher LS BCVI.
