Hepatic artery pseudoaneurysm rupture: A case report. Trauma Case Rep 2023; 48:100970. [PMID: 38035049 PMCID: PMC10687021 DOI: 10.1016/j.tcr.2023.100970] [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: 11/20/2023] [Indexed: 12/02/2023] Open
Abstract
Hepatic artery pseudoaneurysms are an uncommon complication of blunt hepatic trauma typically presenting in a delayed fashion. A 40-year-old male presented to a trauma centre after a 6-metre fall from a construction site with multiple injuries including a grade IV liver laceration centred around the porta hepatis. This liver injury was managed non-operatively. On day sixteen of admission, he had a sudden cardiac arrest from haemorrhagic shock with a subsequent CT demonstrating a ruptured extrahepatic proper hepatic artery pseudoaneurysm. Despite laparotomy and vessel repair, he died from pulmonary complications of aspiration pneumonia and acute lung injury associated with massive transfusion. The literature demonstrates conflicting views regarding the utility of repeat CT to detect a pseudoaneurysm in asymptomatic, non-operatively managed patients with blunt hepatic trauma. In particular, the literature does not distinguish the utility of repeat routine CT for intrahepatic and extrahepatic hepatic artery pseudoaneurysm, the latter if which is rarer. Current guidelines recommend against it, but there are observational studies suggesting utility, particularly in high grade (≥IV) liver injury. In patients with a high-grade injury extending to the porta hepatis, repeat imaging should be considered to detect possible pseudoaneurysm.

Predictors of need for endovascular intervention in hepatic trauma. Abdom Radiol (NY) 2023; 48:1131-1139. [PMID: 36520161 DOI: 10.1007/s00261-022-03765-1] [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: 09/14/2022] [Revised: 11/24/2022] [Accepted: 11/26/2022] [Indexed: 12/23/2022]
Abstract
PURPOSE Non-operative management of hepatic trauma with adjunctive hepatic arterial embolization (HAE) is widely accepted. Despite careful patient selection utilizing CTA, a substantial proportion of angiograms are negative for arterial injury and no HAE is performed. This study aims to determine which CT imaging findings and clinical factors are associated with the presence of active extravasation on subsequent angiography in patients with hepatic trauma. MATERIALS AND METHODS The charts of 243 adults who presented with abdominal trauma and underwent abdominal CTA followed by conventional angiography were retrospectively reviewed. Of these patients, 49 had hepatic injuries on CTA. Hepatic injuries were graded using the American association for the surgery of trauma (AAST) CT classification, and CT images were assessed for active contrast extravasation, arterial pseudoaneurysm, sentinel clot, hemoperitoneum, laceration in-volving more than 2 segments, and laceration involving specific anatomic landmarks (porta hepatis, hepatic veins, and gallbladder fossa). Medical records were reviewed for pre- and post-angiography blood pressures, hemoglobin levels, and transfusion requirements. Angiographic images and reports were reviewed for hepatic arterial injury and performance of HAE. RESULTS In multivariate analysis, AAST hepatic injury grade was significantly associated with increased odds of HAE (Odds ratio: 2.5, 95% CI 1.1, 7.1, p = 0.049). Univariate analyses demonstrated no significant association between CT liver injury grade, CT characteristics of liver injury, or pre-angiographic clinical data with need for HAE. CONCLUSION In patients with hepatic trauma, prediction of need for HAE based on CT findings alone is challenging; such patients require consideration of both clinical factors and imaging findings.

Post-traumatic intrahepatic pseudoaneurysm: A case of successful conservative treatment. Radiol Case Rep 2022; 18:895-898. [PMID: 36593921 PMCID: PMC9804004 DOI: 10.1016/j.radcr.2022.11.078] [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] [Received: 09/29/2022] [Revised: 11/23/2022] [Accepted: 11/29/2022] [Indexed: 12/24/2022] Open
Abstract
Although post-traumatic intrahepatic pseudoaneurysms are rare in adults and even more uncommon in children, this serious complication can result in life-threatening bleeding. Most case studies have recommended surgical or endovascular interventions for preventing rupture or managing the bleeding from a ruptured intrahepatic pseudoaneurysm. Some studies also reported pseudoaneurysms could resolve without intervention and advised conservative therapy. In this case study, we describe a 19-month-old boy diagnosed with an intrahepatic pseudoaneurysm, upper gastrointestinal bleeding from the biliary tract, and hematoma infection. The patient received successful conservative treatment. After 36 days, the patient was discharged without signs of gastrointestinal bleeding and the steady shrinkage of the hematoma surrounding the pseudoaneurysm. The pseudoaneurysm and hematoma vanished at follow-up 18 months after the trauma. Conservative treatment may be considered a viable option, particularly for cases of post-traumatic intrahepatic pseudoaneurysms in children.

A novel inflatable device for perihepatic packing and hepatic hemorrhage control: A proof-of-concept study. Injury 2022; 53:103-111. [PMID: 34507832 DOI: 10.1016/j.injury.2021.08.027] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/02/2021] [Revised: 08/04/2021] [Accepted: 08/24/2021] [Indexed: 02/02/2023]
Abstract
INTRODUCTION Uncontrolled bleeding is the primary cause of death in complex liver trauma and perihepatic packing is regularly utilized for hemorrhage control. The purpose of this study was to investigate the effectiveness of a novel inflatable device (the airbag) for perihepatic packing using a validated liver injury damage control model in swine. MATERIAL AND METHODS The image of the human liver was digitally isolated within an abdominal computerized tomography scan to produce a silicone model of the liver to mold the airbag. Two medical grade polyurethane sheets were thermal bonded to the configuration of the liver avoiding compression of the hepatic pedicle, hepatic veins, and the suprahepatic vena cava after inflation. Yorkshire pigs (n = 22) underwent controlled hemorrhagic shock (35% of the total blood volume), hypothermia, and fluid resuscitation to reproduce the indications for damage control surgery (coagulopathy, hypothermia, and acidosis) prior to a liver injury. A 3 × 10 cm rectangular segment of the left middle lobe of the liver was removed to create the injury. Subsequently, the animals were randomized into 4 groups for liver damage control (240 min), Sponge Pack (n = 6), Pressurized Airbag (n = 6), Vacuum Airbag (n = 6), and Uncontrolled (n = 4). Animals were monitored throughout the experiment and blood samples obtained. RESULTS Perihepatic packing with the pressurized airbag led to significantly higher mean arterial pressure during the liver damage control phase compared to sponge pack and vacuum airbag 52 mmHg (SD 2.3), 44.9 mmHg (SD 2.1), and 32 mmHg (SD 2.3), respectively (p < 0.0001), ejection fraction was also higher in that group. Hepatic hemorrhage was significantly lower in the pressurized airbag group compared to sponge pack, vacuum airbag, and uncontrolled groups; respectively 225 ml (SD 160), 611 ml (SD 123), 991 ml (SD 385), 1162 ml (SD 137) (p < 0001). Rebleeding after perihepatic packing removal was also significantly lower in the pressurized airbag group; respectively 32 ml (SD 47), 630 ml (SD 185), 513 ml (SD 303), (p = 0.0004). Intra-abdominal pressure remained similar to baseline, 1.9 mmHg (SD 1), (p = 0.297). Histopathology showed less necrosis at the border of the liver injury site with the pressurized airbag. CONCLUSION The pressurized airbag was significantly more effective at controlling hepatic hemorrhage and improving hemodynamics than the traditional sponge pack technique. Rebleeding after perihepatic packing removal was negligible with the pressurized airbag and it did not provoke hepatic injury.

Transcatheter arterial embolization for severe blunt liver injury in hemodynamically unstable patients: a 15-year retrospective study. Scand J Trauma Resusc Emerg Med 2021; 29:66. [PMID: 34256826 PMCID: PMC8278697 DOI: 10.1186/s13049-021-00881-7] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/15/2020] [Accepted: 04/21/2021] [Indexed: 11/18/2022] Open
Abstract
Background Transcatheter arterial embolization (TAE) is the first-line nonsurgical treatment for severe blunt liver injury in patients, whereas operative management (OM) is recommended for hemodynamically unstable patients. This study investigated the comparative efficacy of TAE in hemodynamically unstable patients who responded to initial infusion therapy. Methods This retrospective study enrolled patients with severe blunt liver injuries, which were of grades III–V according to the American Association for the Surgery of Trauma Organ Injury Scale (OIS). Patients who responded to initial infusion therapy underwent computed tomography to determine the treatment plan. A shock index > 1, despite undergoing initial infusion therapy, was defined as hemodynamic instability. We compared the clinical outcomes and mortality rates between patients who received OM and those who underwent TAE. Results Sixty-two patients were included (eight and 54 who underwent OM and TAE, respectively; mean injury severity score, 26.6). The overall in-hospital mortality rate was 6% (13% OM vs. 6% TAE, p = 0.50), and the hemodynamic instability was 35% (88% OM vs. 28% TAE, p < 0.01). Hemodynamically unstable patients who underwent TAE had 7% in-hospital mortality and 7% clinical failure. Logistic regression analysis showed that the treatment choice was not a predictor of outcome, whereas hemodynamic instability was an independent predictor of intensive care unit stay ≥7 days (odds ratio [OR], 3.80; p = 0.05) and massive blood transfusion (OR, 7.25; p = 0.01); OIS grades IV–V were predictors of complications (OR, 6.61; p < 0.01). Conclusions TAE in hemodynamically unstable patients who responded to initial infusion therapy to some extent has acceptable in-hospital mortality and clinical failure rates. Hemodynamic instability and OIS, but not treatment choice, affected the clinical outcomes.

Abstract
Background The treatment of hepatic injury can be complex. Medical clinical centers are often the first line hospitals for the diagnosis and treatment of hepatic trauma in China. The aim of the study is to summarize the experience in the diagnosis and treatment of hepatic trauma in one medical clinical center in China. Methods This retrospective study included patients with hepatic trauma admitted between January 2002 and December 2019 at the Xishan People’s Hospital of Wuxi. The outcomes were cure rate and death within 14 days post-discharge. Results Among the 318 patients with hepatic trauma, 146 patients underwent surgical treatment, and 172 received conservative treatment; three patients were transferred to other hospitals for further treatment; 283 patients were cured, and 35 died. Severe hepatic trauma occurred in 74 patients, with a mortality rate of 31.1% and accounting for 65.7% of total mortality. American Association for the Surgery of Trauma (AAST) grading ≥ III (OR = 3.51, 95%CI: 1.32–9.37, P = 0.012) and multiple organ injury (OR = 7.51, 95%CI: 2.51–22.46, P < 0.001) were independently associated with death. Among patients with AAST grading ≥ III, surgery was an independent protective factor for death (OR = 0.08, 95%CI: 0.01–0.45, P = 0.004). Among patients with ASST ≥ III and who underwent surgery, age (OR = 5.29, 95%CI: 1.37–20.33, P = 0.015) and peri-hepatic packing (PHP) (OR = 5.54, 95%CI: 1.43–21.487, P = 0.013) were independently associated with death. Conclusions AAST grading ≥ III and multiple organ injury were independently associated with death. Among patients with AAST grading ≥ III, surgery was an independent protective factor for death. Among patients with ASST ≥ III and who underwent surgery, age and PHP were independently associated with death.

Abstract
BACKGROUND The trend in liver trauma management has progressively become increasingly conservative. However, a vast majority of literature focuses heavily on the management of blunt trauma. This study reviews the management of hepatic trauma at a major trauma center in a developing world setting, in order to compare blunt and penetrating liver trauma and to define current management algorithms and protocols. METHODS All patients who sustained liver trauma between 2012 to 2018 were identified in the Hybrid Electronic Medical Registry and extracted for further analysis. RESULTS A total of 808 patients with hepatic trauma were managed by our trauma center. There were 658 males and 150 females. The mean age was 30 years (standard deviation 13.3). A total of 68 patients died (8.2%) and a total of 290 (35%) patients required intensive care unit admission. The mean presenting shock index was 0.806 (standard deviation 0.67-1.0), the median Injury Severity Score was 18 (interquartile range 10-25) and the mean Revised Trauma Score was 12 (standard deviation 11-12). There were 367 penetrating and 441 blunt liver injuries. The age distribution was similar in both groups. There were significantly less females in the penetrating group. The shock index and the Injury Severity Score on presentation were significantly worse in the blunt group, respectively: 0.891 (standard deviation 0.31) versus 0.845 (standard deviation 0.69) (p < 0.001) and score 21 (interquartile range 13-27) versus 16 (interquartile range 9-20) (p < 0.01). The opposite applied to the Revised Trauma Score of 11.75 (standard deviation 0.74) versus 11.19 (standard deviation 1.3) (p < 0.001). There were significantly more associated intra-abdominal injuries in the penetrating group than the blunt group, in particular that of hollow organs, and 84% of patients with a penetrating injury underwent a laparotomy while only 33% of the blunt injuries underwent a laparotomy. The mortality rate was comparable between both groups. CONCLUSION Hepatic trauma is still associated with a high morbidity rate, although there have been dramatic improvements in mortality rates over the last three decades. The mortality rates for blunt and penetrating liver trauma are now similar. Non-operative management is feasible for over two-thirds of blunt injuries and for just under 20% of penetrating injuries.

Abstract
Objective: To evaluate the safety and effectiveness of NOM (non-operative management) in the treatment of blunt liver trauma, following a standardized treatment protocol. Methods: All the hemodynamically stable patients with computed tomography (CT) diagnosis of blunt liver trauma underwent NOM. It included strict clinical and laboratory observation, 48-72h contrast enhanced ultrasonography (CEUS) or CT follow-up, a primary angioembolization in case of admission CT evidence of vascular injuries and a secondary angioembolization in presence of vascular injuries signs at follow-up CEUS. Results: 181 patients (85.4%) [55 (30.4%) women and 126 (69.6%) men, median age 39 (range 14–71)] were included. Of these, 63 patients (34.8%) had grade I, 48 patients (26.5%) grade II, 39 patients (21.5%) grade III, 21 patients (11.6%) grade IV and 10 patients (5.5%) grade V liver injuries. The overall success rate of NOM was 96.7% (175/181). There was not significant difference in the success rate between the patients with different liver injuries grade. Morbidity rate was 7.4% (13/175). Major complications (2 bilomas, 1 liver hematoma and 2 liver abscesses) were successfully treated by CEUS or CT guided drainage. Eighteen (18/181) patients (9.9%) underwent angioembolization with successful results. Conclusion: Non-operative management of blunt liver trauma represents a safe and effective treatment for both minor and severe injuries, achieving an high success rate and an acceptable morbidity rate. The angiographic study with embolization, although required only in selected cases of vascular injuries, represents a fundamental therapeutic option in a significant percentage of patients.

Surgical intervention for paediatric liver injuries is almost history - a 12-year cohort from a major Scandinavian trauma centre. Scand J Trauma Resusc Emerg Med 2016; 24:139. [PMID: 27899118 PMCID: PMC5129239 DOI: 10.1186/s13049-016-0329-x] [Citation(s) in RCA: 7] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/27/2016] [Accepted: 11/15/2016] [Indexed: 11/18/2022] Open
Abstract
Background Although nonoperative management (NOM) has become standard care, optimal treatment of liver injuries in children is still challenging since many of these patients have multiple injuries. Moreover, the role of angiography remains poorly defined, and a high index of suspicion of complications is warranted. This study reviews treatment and outcomes in children with liver injuries at a major Scandinavian trauma centre over a 12-year period. Methods Patients <17 years old with liver injury admitted to Oslo University Hospital Ullevaal during the period 2002-2013 were retrospectively reviewed. Data were compiled from the institutional trauma registry and medical records. Results A total of 66 children were included. The majority was severely injured as reflected by a median injury severity score of 20.5 (mean 22.2). NOM was attempted in 60 (90.9%) patients and was successful in 57, resulting in a NOM success rate of 95.0% [95% CI 89.3 to 100]. Only one of the three NOM failures was liver related, occurred in the early part of the study period, and consisted in operative placement of drains for bile leak. Two (3.0%) patients underwent angiographic embolization (AE). Complications occurred in 18 (27.3% [95 % CI 16.2 to 38.3]) patients. Only 2 (3.0%) patients had liver related complications, in both cases bile leak. Six (9.1%) patients underwent therapeutic laparotomy for non-liver related injuries. Two (3.0%) patients died secondary to traumatic brain injury. Discussion This single institution paediatric liver injury cohort confirms high attempted NOM and NOM success rates even in patients with high grade injuries and multiple accompanying injuries. AE can be a useful NOM adjunct in the treatment of paediatric liver injuries, but is seldom indicated. Moreover, bile leak is the most common liver-related complication and the need for liver-related surgery is very infrequent. Conclusion NOM is the treatment of choice in almost all liver injuries in children, with operative management and interventional radiology very infrequently indicated.

Hepatic "BOLSA" a novel method of perihepatic wrapping for hepatic hemorrhage "BOLSA". Int J Surg Case Rep 2015; 13:99-102. [PMID: 26188978 PMCID: PMC4529640 DOI: 10.1016/j.ijscr.2015.06.007] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/13/2015] [Revised: 06/02/2015] [Accepted: 06/07/2015] [Indexed: 12/04/2022] Open
Abstract
Perihepatic packing has significant inherent risks. Vicryl liver mesh wrap does not possess the complications of packing. BOLSA construction is simpler to construct than previously describe liver mesh wrap.
Introduction Severe traumatic liver hemorrhage quickly leads to exsanguination. Perihepatic packing is frequently used in damage control surgery. This method can be unsuccessful and accompanied by complications. Vicryl mesh wraps have been described in the treatment of liver hemorrhage. In this report, we describe an enhanced technique of hepatic wrapping in a case of hepatic bleeding after liver biopsy in a coagulopathic patient. The technique is called the hepatic “BOLSA” (Bag on Liver Supporting Anti-Hemorrhage). Presentation of case A 59 year old male presented in the recovery room after liver biopsy of a mass, followed by angio-embolization of the hepatic mass 9 h earlier. The patient was acidotic, coagulopathic, and demonstrated intra-abdominal hypertension. Computed tomography demonstrated perihepatic fluid. The patient continued hemorrhaging despite attempts to correct coagulopathy by transfusion. Multiple operating room visits were required where a combination of packing and hemostatic agents could not stop hepatic venous parenchymal hemorrhage. Mesh wrap consisting of Vicryl and PDS suture were used to create the “BOLSA” to achieve hemostasis. Discussion Perihepatic packing compromises pulmonary excursion, elevates intra-abdominal pressure, is a risk factor for sepsis, and requires an additional trip to the operating room for removal. The use of Vicryl mesh wrap obviates these complications. Previously described mesh wraps require anchoring. The self-supporting structure of the BOLSA simplifies construction and application. Conclusion The BOLSA is an effective tool in treatment of severe liver hemorrhage in coagulopathic patients. It is the modern simplification of hepatic wrapping and the solution to the side effects of perihepatic packing.

Abstract
INTRODUCTION Biliary peritonitis complicating blunt hepatic trauma is a rare but potentially lethal condition. PRESENTATION OF CASE A 17-year old male patient who sustained a complex grade IV blunt hepatic trauma presented with severe haemorrhagic shock after an initial laparotomy in another hospital. An urgent exploratory laparotomy revealed a shattered posterior section of the right liver and suture haemostasis of the lacerated liver surface was performed. Postoperatively, the patient developed generalized biliary peritonitis and another laparotomy with peritoneal lavage and drainage was performed on postoperative day 12. However, ongoing manifestations of peritonitis and sepsis necessitated a third laparotomy 6 days later. This revealed ongoing biliary peritonitis due to major intra-hepatic bile duct injury. A partial hepatectomy with intra-operative trans-hepatic biliary stenting was undertaken. Postoperative recovery was uneventful and the biliary fistula healed completely by the end of the second postoperative week. DISCUSSION Major intra-hepatic bile duct injury following blunt hepatic trauma is an extremely rare cause of biliary peritonitis. CONCLUSION The combination of partial hepatectomy with intra-operative trans-hepatic biliary stenting proved to be a safe and effective method for treatment of biliary peritonitis due to major intra-hepatic bile duct injury following blunt hepatic trauma when non-operative management fails.

Abstract
Management of massive liver trauma (grades IV-VI) is associated with high morbidity and mortality. It can pose serious challenges to treating physician and requires multimodality interventions. For a successful outcome, timing of intervention is crucial. We report a case of grade V hepatic injury treated successfully with angioembolization, laparoscopic lavage, and endoscopic stenting during a time period from admission to discharge on the 24th day. Angioembolization was performed at admission after resuscitation as CT scan showed active extravasation in the arterial phase. Laparoscopic lavage and drainage was performed on the fifth day as abdominal inflammatory response failed to respond to medical management. There was biliary component of abdominal fluid noticed during laparoscopy, which manifested by postoperative localized biliary fistula; hence endoscopic stenting of the bile duct was performed on the seventh day. The patient recovered well with timely minimal invasive approach and was fine at 1 year follow-up.

Non-operative management of hepatic trauma and the interventional radiology: an update review. Indian J Surg 2012; 75:339-45.

Abstract
The growing trend to manage hepatic injuries nonoperatively has been increasing demand for advanced endovascular interventions. This brings up the necessity for general and trauma surgeons to update their knowledge in such matter. Effective treatment mandates a multispecialty team effort that is usually led by the trauma surgeon and includes vascular surgery, orthopedics, and, increasingly, interventional radiology. The focus on hemorrhage control and the angiographer's unique access to vascular structures gives interventional radiology (IR) an important and increasingly recognized role in the treatment of patients with hemodynamic instability. Our aim is to review the basic concepts of IR primarily in hepatic trauma and secondarily in some other special situations. A liver vascular anatomy review is also needed for better understanding the roles of IR. As a final point we propose a guideline for the operative/nonoperative management of traumatic hepatic injuries. The benefit of multidisciplinary approach (TAE) appears to be a powerful weapon in the medical arsenal against the high mortality of injured trauma liver patients.

A new method for hepatic resection and hemostasis: absorbable plaque and suture. Eurasian J Med 2010; 42:1-4.

Abstract
OBJECTIVE Blunt and penetrating hepatic injuries are conditions that are frequently encountered in emergency surgeries, and they involve high mortality morbidity. In the handling of such injuries, methods ranging from the application of simple cauterization and suturing for hemostasis to hepatic lobectomies, which might involve the removal of the greater part of the organ, have been defined. Due to the organ's fragility and susceptibility to bleeding, elective hepatic resections necessitate both surgical experience and technological equipment. Therefore, the demand still exists for an affordable and easy-to-use-method that could be applied by all centers. MATERIALS AND METHODS To meet this demand, we have developed a method of hemorrhage control via sutures supported by absorbable plaques that provide effective compression and prevent the suture from cutting the tissue during the application of the sutures in the treatment of such fragile organs as the liver. In our method, we have achieved hemostasis by bilaterally compressing the tissue through strong ties after placing, on the part of the tissue on which the sutures are applied, absorbable and flexible plaques that prevent the suture from cutting the tissue during the application of a polyglactin suture to the solid organ. To prevent dislocation of the plaques, we have fastened the sutures by reeving them through the holes made in the plaques. RESULTS We have demonstrated the success and the practicality of our method by applying it on four pigs; we experimentally inflicted hepatic injuries on two pigs, and we performed resection on the other two pigs. The hepatic hemorrhages we developed in both of the animals were successfully restrained by the use of our method. On the other hand, two resections were performed on the right and left lobes of the other two animals. There were no hemorrhages during the surgery, and the procedure took 45 minutes in total. No postoperative complications occurred. While the liver function test values were high on the seventh day, due to the operation, they were observed to be normal on the thirtieth day. After the laparotomies, performed six months later, we observed that the plaques as well as the sutures were absorbed and that the injured tissues were completely healed. Additionally, it was observed during the pathological examination that the tissues beneath the area of application were healed through fibrosis and that the liver had no other pathologies. CONCLUSIONS In conclusion, we believe that the method can be safely used in hepatic resections or traumatic hemorrhages in the proper locations.

Post-traumatic hepatic artery pseudoaneurysm treated with endovascular embolization and thrombin injection. World J Hepatol 2010; 2:87-90. [PMID: 21160978 PMCID: PMC2999272 DOI: 10.4254/wjh.v2.i2.87] [Citation(s) in RCA: 27] [Impact Index Per Article: 1.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/15/2009] [Revised: 01/14/2010] [Accepted: 01/21/2010] [Indexed: 02/06/2023] Open
Abstract
Post-traumatic hepatic artery pseudoaneurysm is uncommon, appearing in approximately 1% of hepatic trauma cases. Most are extrahepatic (80%) and have a late onset. Although they are usually asymptomatic, they should always be treated becasue of the high risk of complications, especially breakage. Currently the treatment of choice is endovascular embolization with coils or the exclusion of the pseudoaneurysm using other intravascular devices. Recently there have been accounts of a treatment that combines embolization with coils and image-guided percutaneous human thrombin injection. We present a case of post-traumatic hepatic artery pseudoaneurysm that was successfully treated using this combined technique.

Abstract
Liver transplantation has been reported in the literature as an extreme intervention in cases of severe and complicated hepatic trauma. The main indications for liver transplant in such cases were uncontrollable bleeding and postoperative hepatic insufficiency. We here describe four cases of orthotopic liver transplantation after penetrating or blunt liver trauma. The indications were liver failure, extended liver necrosis, liver gangrene and multiple episodes of gastrointestinal bleeding related to portal hypertension, respectively. One patient died due to postoperative cerebral edema. The other three patients recovered well and remain on immunosuppression. Liver transplantation should be considered as a saving procedure in severe hepatic trauma, when all other treatment modalities fail.

Management of resistant cardiac depression after hepatic trauma controlled with a packing procedure. Eurasian J Med 2009; 41:66-69.

Abstract
In addition to hemorrhage, which is one of the most well-known factors, there are many other causative factors for serious hypotension after hepatic trauma. In this report, we present patients with persistent cardiac depression after perihepatic packing due to high grade liver injury and report on treatment modalities, including the early second-look procedure. Three patients with isolated hepatic trauma were included. Two of the patients who underwent perihepatic packing were transferred from outside hospitals, and one patient required repacking due to severe hemorrhage. All patients had grade IV injuries due to blunt (n=2) or penetrating injury (n=1). In the intensive care unit, central venous pressure (8, 12, 13 mmHg) and hematocrit (26, 27, 29%) were in the normal range, but blood pressure (40/60, 50/70, 45/75mmHg) was abnormal despite the use of inotropic support. The three patients underwent an unpacking procedure 8, 10, and 14 hours later, respectively. Inotropic support was not required after postoperative hours 3, 5, and 6, respectively. The management of post reperfusion syndrome due to hepatic trauma can be achieved, but close collaboration between the surgeon and anesthesiologist is absolutely necessary. In the case of resistance cardiac depression in patients with packing, second-look procedures should be performed as early as possible.

Abstract
A 23-year-old man with post-traumatic hepatic artery pseudo-aneurysm and subphrenic liver abscess was admitted. He underwent coil embolization of hepatic artery pseudo-aneurysm. The pseudo-aneurysm was successfully obstructed and subphrenic liver abscess was controlled. Super-selective trans-catheter coil embolization may represent an effective treatment for hepatic artery pseudo-aneurysm combined with subphrenic liver abscess in the absence of other therapeutic alternatives.
