Abstract
OBJECTIVE True superficial femoral artery aneurysms (SFAAs) are rare and traditionally treated by open repair. However, the endovascular approach excluding the aneurysm sac with a covered stent may be an alternative. This study aimed to compare the outcomes of the open and endovascular repair of SFAAs. METHODS This is a retrospective, observational, monocentric study. The main endpoints were: technical success, limb salvage and primary patency rate, and hospitalisation time. RESULTS We identified 49 SFAAs in 40 patients; the mean age was 73.3±10.1 years, the mean diameter of SFAAs was 5.41±3.64cm, and 61.2% were symptomatic for ischaemic or compression-related signs. The indication for open repair was given mainly for complex SFAAs involving the distal third of the superficial femoral artery and with an ipsilateral popliteal aneurysm. Among the 36 open-repair patients, 33 underwent ligation and revascularisation via bypass or graft interposition, and 3 patients underwent simple ligation without revascularisation. The endovascular approach was adopted mainly for aneurysms located in the medial third of the SFAA, which underwent covered stenting in 12 patients and coil embolisation in 1 patient. The technical success was 100% in all cases. There were no statistical differences in terms of primary patency and limb salvage rate between groups at two and four years. The mean hospitalisation time was 10±4 and 3±1 days after open and endovascular treatment, respectively. CONCLUSIONS The endovascular approach may be a valid alternative for isolating SFAAs offering good results and shorter hospitalisation. Open repair remains a valid approach, particularly in complex aneurysms.

Endovascular Revascularisation versus Open Surgery with Prosthetic Bypass for Femoro-Popliteal Lesions in Patients with Peripheral Arterial Disease. J Clin Med 2023; 12:5978. [PMID: 37762924 PMCID: PMC10532352 DOI: 10.3390/jcm12185978] [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: 08/05/2023] [Revised: 09/12/2023] [Accepted: 09/13/2023] [Indexed: 09/29/2023] Open
Abstract
Aim: Complex atherosclerotic femoro-popliteal lesions have traditionally been treated with bypass surgery. A prosthetic graft is used to save the vein graft for more distal revascularisations or when a vein graft is unavailable. The endovascular approach has gained popularity and is offered as a first-line strategy for complex lesions. This study aimed to evaluate whether endovascular procedures can be used as a first-line treatment strategy for complex native femoro-popliteal lesions over open surgery with prosthetic bypass in patients with peripheral arterial disease (PAD). Methods: This single-centre retrospective observational study was conducted between 2013 and 2021; it included patients with symptomatic PAD who required limb revascularisation at the femoro-popliteal segment and who had complex lesions. The primary endpoints analysed were technical success, primary patency, freedom from clinically driven target lesion revascularisation (cdTLR), freedom from major adverse limb and cardiovascular events (MALE and MACE, respectively), freedom from limb loss, and survival. The secondary endpoints were length of in-hospital stay, and duration and costs of the procedure. Results: We identified 185 limbs among 174 suitable candidates for comparison, wherein 105 were treated with an endovascular procedure and 80 with a femoro-popliteal prosthetic bypass. Most patients in both groups presented with chronic limb-threatening ischaemia, and >90% of them had an American Society of Anesthesiologists (ASA) physical status classification of >3. The endovascular group had more octogenarians (p = 0.02) and patients with coronary disease (p = 0.004). The median follow-up was 30 months. The technical failure rate for endovascular procedures was 4.7%, versus 0% in the open group (p = 0.047). Freedom from MACE was similar in both groups. The endovascular group showed superior primary patency (p < 0.0001), cdTLR (p < 0.0001), MALE (p < 0.0001), and freedom from limb loss (p = 0.0018) at 24 and 48 months. Further analysis performed for the open above-the-knee sub-group showed that the aforementioned endpoints were similar between the groups at 12 months and were better in the endovascular group at 24 and 48 months. Procedural time and in-hospital stay were longer in the open group than in the endovascular group (p < 0.0001 and p < 0.001, respectively). The procedural cost in the endovascular group was 10-fold lower than that in the prosthetic bypass group. Conclusions: Endovascular procedures are safe for treating complex femoro-popliteal lesions in patients at a high risk for surgery and show better outcomes at 24 months than prosthetic bypasses do. The latter may be considered as an alternative should endovascular treatment fail.

Abstract
OBJECTIVES The treatment of choice for acute and isolated extracranial internal carotid artery (eICA) occlusion remains, to date, controversial. Although intravenous thrombolysis is recommended, its effectiveness is generally low. This retrospective study aims to assess the clinical outcome and the role of CT perfusion in symptomatic patients who underwent carotid endarterectomy (CEA) for acute occlusion of the eICA. MATERIALS AND METHODS All the 21 patients presented with stroke-in-evolution, complete patency of intracranial circulation, no evidence of hemorrhagic transformation at CT and a minimum ASPECTS of 6. Clinical improvement was assessed by evaluating the variation of NIHSS and the mRS. We investigated the relationship between NIHSS and the timing of the surgery, the ASPECT score, and the volume of ischemic penumbra at CT perfusion. RESULTS Median NIHSS on admission was 9 (range 1-24) and it decreased to 4 (range 0-35) 24 h after surgery, improving in 76.2% of patients. Patients with an ASPECTS of 6 (3 patients) showed an improvement of 66.7%, while it was of 81.8% in those starting with a score of 9 or 10 (11 patients). A mRS between 0 and 2 after 3 months was achieved in 12 out of 21 patients. The average time elapsing between surgery and symptom onset was 410 min (range 70-1070 min). Fourteen patients treated within 8 h from symptoms onset showed a clinical improvement of 85.7%, compared to a 57.1% for those which underwent later surgery. Four patients underwent thrombolytic therapy before CEA showing postoperative clinical improvement and no intracranial hemorrhage. Among the 14 patients who underwent CT perfusion, the median ischemic penumbra volume was 112 cc in those with clinical improvement (10 patients) and only 84 cc in those with worse clinical outcomes (4 patients). CONCLUSIONS Emergency CEA in isolated eICA occlusion has proved to be a safe and effective treatment option in selected patients. CT perfusion, imaging the ischemic penumbra and quantifying the tissue suitable for reperfusion, offers a valid support in the diagnostic-therapeutic workup. Indeed, we can infer that the area of the ischemic penumbra is directly proportional to the margin of clinical improvement after revascularization, supposing that the appropriate intervention timing is respect.

Exercise-based functional recovery from severe upper extremity arterial disease due to bilateral subclavian artery obstruction in a person with giant cell arteritis. J Vasc Surg Cases Innov Tech 2023; 9:101179. [PMID: 37427039 PMCID: PMC10323406 DOI: 10.1016/j.jvscit.2023.101179] [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: 12/30/2022] [Accepted: 03/23/2023] [Indexed: 07/11/2023] Open
Abstract
We report the case of a 71-year-old woman diagnosed with giant cell arteritis with bilateral subclavian and axillary obstruction and severe arm claudication that occurred 3 months earlier and was non-regressed after corticosteroids. Before possible revascularization, the patient was initiated to a personalized home-based graded exercise program including walking, hand-bike pedaling, and muscle strength training. During the 9 months of treatment, the patient progressively improved radial pressure values (10 to 85 mmHg), hand temperature values by infrared-thermography (+2.1 °C), arm endurance, and forearm muscle oxygenation by near-infrared spectroscopy. Home-based graded exercise proved to be a noninvasive option for upper limb claudication.

Primary Drug-Coated Balloon Versus Drug-Eluting Stent for Native Atherosclerotic Femoropopliteal Lesions: A Systematic Review and Meta-Analysis. Ann Vasc Surg 2023; 92:294-303. [PMID: 36746268 DOI: 10.1016/j.avsg.2023.01.043] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/28/2022] [Revised: 12/29/2022] [Accepted: 01/22/2023] [Indexed: 02/05/2023]
Abstract
BACKGROUND In this systematic review and meta-analysis, we aimed to compare drug-coated balloon (DCB) to drug-eluting stent (DES) angioplasty as a primary option in patients with femoropopliteal lesions in terms of primary patency and freedom from clinically driven target lesion revascularization (cdTLR) and major adverse limb events (MALE). METHODS A comprehensive literature search was performed using the PubMed and Embase databases. All studies written in English language and reporting data presenting a comparison between patients receiving primary percutaneous balloon angioplasty using the DCB versus primary percutaneous stenting with DES for native femoropopliteal lesions were included in this meta-analysis. RESULTS There were 984 patients with 1,078 femoropopliteal lesions, of which procedures with DCB and DES were performed in 514 and 564 lesions, respectively. Overall, majority patients were men with a mean age of 70.9 years, and there were no significant differences between the 2 groups regarding the cardiovascular comorbidities. With regards to the procedural strategy, there was significant heterogeneity in the DCB group. This included adjunctive procedures such as atherectomy besides the angioplasty of the target vessel, which was reported in 1 study as a part of 32.1% of the procedures in the DCB group. Provisional bare metal stents (pBMS) for residual stenosis and dissection were used in 4 studies with a percentage varying from 14.8 to 25.3%. Overall, at 1 year, all outcomes were similar for all the end points; however, where adjunctive procedures were performed (atherectomy + pBMS) in the DCB group, the outcomes were better (primary patency p.001, freedom cdTLR p.001, and freedom form MALE p.002). In studies where no adjunctive procedures were performed in the DCB group, the results favored the DES group for the primary patency (p.026) and freedom from cdTLR (p.044). CONCLUSIONS DES seems to be superior in terms of cdTLR and primary patency at 1 year when compared to the procedures performed solely with DCB. For DCB to achieve optimal results, further adjunctive procedures such as pBMS and atherectomy are needed. More studies are needed to confirm the superiority of the primary stenting with DES at the femoropopliteal segment.

Abstract
BACKGROUND The purpose is to evaluate the follow-up outcomes after femoro-popliteal stenting with Cook Zilver PTX in a multicenter experience. METHODS Collected data from four Units were retrospectively joined and analyzed considering Zilver PTX deployed from August 2009 according to the instruction for use. Patient demographics, preoperative comorbidities, Rutherford classification, arterial characteristics and stent data were considered. Target lesion revascularization (TLR) was defined as reintervention performed for ≥50% diameter stenosis after recurrent clinical symptoms. Primary outcome was the freedom from TLR (ffTLR) and its risk factors. Secondary outcomes were primary patency (PP) of the stent, amputation-free survival (AFS) and their risk factors. RESULTS Considering 203 patients (mean age: 73.5 years ±10.6; male: 66.5%) and 263 stents (median 2 stents/patient, range 1-5stent/patient), chronic limb-threatening ischemia (CLTI) affected 154 patients (75.9%). The length of the treated lesion was <120 mm in 99 (48.8%), ≥120 mm and <200 mm in 65 (32%) and ≥200 mm in 39 (19.2%) cases, respectively; the reference vessel mean diameter was 5.5±0.7 mm; chronic total occlusion was treated in 153 (75.4%) patients, the popliteal artery was involved in 56 (27.6%) cases and prior endovascular intervention was performed in 27 (13.3%) cases. Two or more crural run-off vessels were patent in 124 (61.1%). Mean follow-up was 23.2 months ±21.3. At 1, 2 and 3 years, the ffTLR was 90.6±4.2%, 86.4±6.1% and 80.4±8.3%, respectively, and the PP was 85.6±5.0%, 74.2±7.6% and 72.7±8.2%, respectively. Negative prognostic factor for ffTLR and PP was the reference vessel diameter (P=0.001 and P<0.001, respectively). At 1, 2 and 3 years, the AFS was 81.8±6.0%, 75.5±7.1% and 74.2±7.5% respectively; coronary artery disease (P=0.041) and CLTI (P=0.011) resulted negative prognostic factors. CONCLUSIONS In the real-world practice, around 3/4 of patients were treated for CLTI. The rate of ffTLR is high, and PP is substantially lower. A small vessel diameter (<5 mm) is a negative factor for both ffTLR and PP. The rate of AFS is about 75% at 2 years and CLTI and coronary artery disease are negative prognostic factors.

Superficial femoral artery access for infrainguinal antegrade endovascular interventions in the hostile groin: A prospective randomized study. Ann Vasc Surg 2022; 86:127-134. [PMID: 35460853 DOI: 10.1016/j.avsg.2022.04.017] [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: 01/23/2022] [Revised: 04/01/2022] [Accepted: 04/08/2022] [Indexed: 11/01/2022]
Abstract
INTRODUCTION In a hostile groin, it may be difficult to perform antegrade endovascular procedures at the lower extremities using the ipsilateral common femoral artery as vascular access; therefore, the use of the ipsilateral superficial femoral artery (SFA) could be a useful alternative. In this study, we evaluated the feasibility and safety of ultrasound-guided SFA puncture versus traditional SFA cutdown to achieve arterial access. METHODS This prospective observational randomized study examined patients with symptomatic peripheral arterial disease who required endovascular interventions at the lower extremities. A hostile groin was defined as high femoral bifurcation, obesity, and surgical scarring due to previous surgical interventions. A 6-Fr sheath (12 cm long; ULTIMUM™ EV INTRODUCER; Abbott, Plymouth, MN, USA) was used in all procedures. In the percutaneous group, the puncture was performed under ultrasound guidance and hemostasis was performed using a percutaneous closure device (PCD) (Angioseal Vip 6-Fr; Terumo Medical Corporation, Somerset, NJ, USA). The primary endpoints were technical success and perioperative complications. The secondary endpoints were the time required for the management of vascular access and the type of anesthesia administered. RESULTS Between 2020 and 2021, 107 patients who underwent antegrade revascularization were enrolled. SFA was achieved in 50 cases by the femoral cutdown technique (c-group) and in 57 cases by percutaneous ultrasound-guided puncture (p-group). In the c-group, the time from incision to sheath introduction and the time of suturing the artery and wound closure was 35 ± 8 min. In the p-group, the time from skin puncture and sheath placement plus that from the sheath removal and hole closure with the PCD was 6 ± 3 min. For the c-group versus p-group, the following variables were as follows: high bifurcation, 10 vs. 6 cases (=p 0.2); severe obesity, 33 vs. 40 cases (p 0.46); and previous surgical groin interventions, 7 vs. 9 cases (p 0.53), respectively. The technical success rates were 100% vs. 96.49% for the c-group vs. p-group, respectively (p 0.63). Two percutaneous puncture failures were managed using the cutdown technique. In the p-group, two post-procedural hematomas were recorded, with only one requiring surgical treatment and two with SFA occlusion to intravascular cap hemostatic dislocation, which were subjected to surgical revision. A total of three percutaneous procedures in the p-group required surgical revision versus none in the c-group (p =0.1). Within 3 months, complications consisted of 6 cases of surgical wound complications in the c-group versus none in the p-group (p 0.009). All procedures in the p-group versus 72% of patients in the c-group were managed with local anesthesia (p<0.0001). CONCLUSIONS The femoral cutdown technique seems to be safe and successful approach for achieving vascular access in cases of hostile groin. Ultrasound-guided puncture and PCD make SFA puncture a successful and safe alternative with an acceptable complications rate. Moreover, it reduces the time required to manage vascular access and can be performed mainly under local anesthesia.

Abstract
Aim: The aim of this study was to evaluate the utility and reliability of temperature foot changes measured by infrared thermography (IRT) for the evaluation of patients with atherosclerotic peripheral arterial disease (PAD) before and after endovascular revascularisation. Methods: This is an observational prospective study carried out on symptomatic PAD patients. Evaluations consisted of a clinical examination, duplex scan with ankle–brachial index calculation (ABI) and IRT measurements with infrared camera FLIR-ONE connected to a smartphone with android technology. Locations on the foot sampled with IRT were the anterior tibial, pedal, posterior and arcuate arteries. Results obtained with IRT on the symptomatic foot were compared to the contralateral foot and with the ABI values obtained bilaterally before and 24 h after revascularisation. Results: Within one year, 40 patients were enrolled, among whom 87,5% suffered from critical limb ischaemia. In three patients, it was impossible to obtain ABI measurements because of ulcerations on the limb. Skin temperature changes obtained by IRT between the symptomatic limb and the contralateral limb had a mean difference of 1.7 °C (range: 1.1–2.2 °C), p < 0.001. There was a positive correlation between ABI and temperature values of the limb needed for treatment before revascularisation (p = 0.025; r = 0.36) and after revascularisation (p = 0.024, r = 0.31). The technical success rate was 100% in all cases, achieving a significant increase in temperature at all points of the foot analysed, with a median change of 2 °C (p < 0.001). Conclusion: IRT is a safe, reliable and simple application. It could be a valuable tool for the assessment of the clinical presentation and severity of foot blood perfusion in symptomatic PAD patients and the evaluation of the technical success of endovascular revascularisation. IRT might have a role in follow-up of revascularisation procedures.

Abstract
BACKGROUND True superficial femoral artery aneurysms (SFAAs) do not occur frequently but carry a high risk of limb loss when they are complicated with thrombosis, distal embolization or rupture. Large aneurysms can also exert a mass effect, compressing adjacent veins and nerves. We performed an updated review of the literature with regard to their incidence, diagnosis, treatment, and outcomes over the years. METHODS A MEDLINE, Excerpta Medica Database (EMBASE) search of papers reporting SFAAs was conducted. Studies reported in the literature were considered for the review regardless of their nature and the number of participants. The available data regarding patient demographics, method of diagnosis, size, location, clinical presentation, therapy, and outcomes were examined. RESULTS Searching from 1967 to the present, we identified 59 papers reporting true SFAAs. Forty-one papers were case reports with 1 case each, 9 papers with 2 cases each and 9 papers reporting case series with more than 3 cases. There was 1 study reporting data on the management of asymptomatic SFAAs. We identified 164 SFA aneurysms, and 84.4% were symptomatic. The mean age of patients at the presentation was 70.2 years (range, 27-96) and 89.4% were men. SFAAs were diagnosed earlier in patients with connective tissue disorders, with a mean age of 35 years (range, 29-43). In 60.2 % of cases are present symptoms related to mass compression, 26,8% with rupture, and 27,3% of cases with ischemic symptoms. Endovascular approach was chosen in 52.6% of SFAAs reported in the last 5 years. CONCLUSIONS The data in the available literature are poor regarding the management of asymptomatic aneurysms, and the conclusions are based mainly on the symptomatic aneurysms reported. Most SFAAs present mainly with symptoms due to mass compression and rupture rather than ischemic symptoms. The endovascular approach is becoming more popular and could become the preferred choice.

Abstract
Venous thromboembolism (VTE) represents an important clinical complication of patients with SARS-CoV-2 infection, and high plasma D-dimer levels could suggest a higher risk of hypercoagulability. We aimed to analyse if laboratory exams, risk assessment scores, comorbidity scores were useful in predicting the VTE in SARS-CoV-2 patients admitted in internal medicine (IM). We evaluated 49 older adults with suspected VTE analysing history and blood chemistry, besides we calculated the Padua Prediction Score, the modified early warning scoring (MEWS) and the modified Elixhauser index (mEI). All patients underwent venous color-doppler ultrasounds of the lower limbs. Out of the 49 patients enrolled (mean age 79.3±14 years), 10 (20.4%) had deep vein thrombosis (DVT), and they were more frequently female (80% vs 20%, p = 0.04). We could not find any association with the Padua Prediction Score, the MEWS, and the mEI. D-dimer plasma levels were also not associated with DVT. In elderly people hospitalized with SARS-CoV-2 infection hospitalized in IM, our data, although limited by the sample size, suggest that prediction and diagnosis of VTE is difficult, due to lack of precise biomarkers and scores.

Abstract
Exercise therapy in the intermediate stages of peripheral artery disease (PAD) represents an effective solution to improve mobility and quality of life (QoL). Home-based programs, although less effective than supervised programs, have been found to be successful when conducted at high intensity by walking near maximal pain. In this randomized trial, we aim to compare a low-intensity, pain-free structured home-based exercise (SHB) program to an active control group that will be advised to walk according to guidelines. Sixty PAD patients aged > 60 years with claudication will be randomized with a 1:1 ratio to SHB or Control. Patients in the training group will be prescribed an interval walking program at controlled speed to be performed at home; the speed will be increased weekly. At baseline and after 6 months, the following outcomes will be collected: pain-free walking distance and 6-min walking distance (primary outcome), ankle-brachial index, QoL by the VascuQoL-6 questionnaire, foot temperature by thermal camera, 5-time sit-to-stand test, and long-term clinical outcomes including revascularization rate and mortality. The home-based pain-free exercise program may represent a sustainable and cost effective option for patients and health services. The trial has been approved by the CE-AVEC Ethics Committee (898/20). Registration details: Clinicaltrials.gov NCT04751890 [Registered: 12 February 2021].

Abstract
OBJECTIVE Diffuse thrombosis represents one of the most predominant causes of death by COVID-19 and SARS-CoV-2 infection seems to increase the risk of developing venous thromboembolic diseases (VTE). Aim of this study is to analyze the relationship between validated predictive scores for VTE such as IMPROVE and IMPROVEDD and: (1) Intensification of Care (IoC, admission to Pulmonology Department or Intensive Care Unit) (2) in-hospital mortality rate 3) 30-days mortality rate. PATIENTS AND METHODS We retrospectively evaluated 51 adult patients with laboratory diagnosis of SARS-CoV-2 infection and calculated IMPROVE and IMPROVEDD scores. All patients underwent venous color-Doppler ultrasound of the lower limbs to assess the presence of superficial vein thrombosis (SVT) and/or deep vein thrombosis (DVT). Patients with normal values of D-dimer did not receive heparin therapy (LMWH); patients with ≥ 4 ULN values of D-dimer or with a diagnosis of DVT were treated with therapeutic LMWH dosage, while the remaining patients were treated with prophylactic LMWH dosages. RESULTS We found strong relations between IMPROVE score and the need for IoC and with the in-hospital mortality rate and between the IMPROVEDD score and the need for IoC. We defined that an IMPROVE score greater than 4 points was significantly associated to in-hospital mortality rate (p = 0.05), while an IMPROVEDD score greater than 3 points was associated with the need for IoC (p = 0.04). Multivariate logistic analysis showed how IMPROVE score was significantly associated to in-hospital and 30-days mortality rates. CONCLUSIONS IMPROVE score can be considered an independent predictor of in-hospital and 30-days mortality.

Abstract
Popliteal artery aneurysms are the most frequent type of peripheral arterial aneurysm and can be repaired by either open or endovascular techniques. An 81-year-old man presented with leg swelling and during duplex ultrasound examination was diagnosed a popliteal aneurysm. The transverse diameter was 3.6 × 4.5cm, length 2.8cm, one run-off vessel patent. The popliteal aneurysm was asymptomatic for clinical signs of limb ischaemia. We opted for an open surgical repair through a posterior approach. During dissection of the popliteal artery above and below the aneurysm, the two non-diseased popliteal extremities appeared to be very close, leading to the decision to perform an end-to-end anastomosis between the two arterial extremities. The patient was discharged after three days with no adverse events. Follow-up consisted of duplex ultrasound examination at one, three and six months, and then annually. At the six-month follow-up there was no restenosis at the anastomosis.

Abstract
INTRODUCTION Infra-inguinal vascular reconstruction with active groin infection is a concerning issue. Using resistant grafts to infection is the most adopted approach. However, in absence of these materials in acute situations, the trans-obturator approach allows for limb revascularisation avoiding the infected site. We evaluated the effectiveness of this approach in patients who needed lower limb revascularisation with an ipsilateral groin infection. MATERIALS AND METHODS A retrospective study was conducted over a four-year period. RESULTS Over this period, 13 patients underwent trans-obturator reconstructions (13 external iliac-popliteal above-knee and one aortobipopliteal above-knee bypass). Seven patients had been previously revascularised and were admitted for graft infection (six infra-inguinal bypasses, one axillo-bifemoral bypass). Four presented with acute limb ischaemia, three with groin haematoma and one with a groin abscess. The remaining cases consisted of drug-addicted patients with injury of femoral vessels due to self-injection of drugs. The patients underwent reconstructions with autologous grafts which complicated early with groin haematoma. After transobturator revascularisation, the groin underwent debridement with applying vacuum-assisted wound closure device. CONCLUSION The transobturator approach could be considered as a chance for lower limb revascularisation in case of ipsilateral groin infection. Moreover, avoiding the infected site allowed us to focus separately and safely on the treatment of the inguinal wound.

Biosynthetic graft failure to replace infected infrainguinal bypass as developing infection due to Morganella morganii leading to disrupture of the anastomosis. Case report. Int J Surg Case Rep 2018; 41:411-413. [PMID: 29546004 PMCID: PMC5699879 DOI: 10.1016/j.ijscr.2017.11.010] [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: 09/02/2017] [Accepted: 11/03/2017] [Indexed: 11/10/2022] Open
Abstract
Infection of infrainguinal bypass is a challenging complication with a high risk rate mortality and limb loss. Biosynthetic grafts are considered as the last chance to deal with bypass infection and if they fail other solutions are required. Besides occlusion of biosynthetic grafts other complications may occur during the follow up such as infection and haemorrhage. Recurrent infection of two different grafts used for infrainguinal bypass makes meaningless the use of other materials at the same surgical site. Extra- anatomical bypass avoiding the compromised and complicated surgical site could be a solution to assure limb salvage and patient survival.
Introduction Biosynthetic prosthesis has become the trend to carry out arterial reconstruction in infected sites since considered to be resistant to infection. Late graft occlusion is the only complication reported in literature so far. We report a case of biosynthetic graft infection which led to early detachment of the femoral anastomosis of a femoral-popliteal above-knee bypass. Material A 76-year-old man developed groin infection 3 months later after performing an ePTFE femoral-popliteal above-knee bypass for critical limb ischemia. He was re-admitted for groin infection involving the vascular structures. Explantation of the existing bypass and its replacement with a biosynthetic graft (omniflow II) was performed. Detachment of the proximal anastomosis occurred 6 days later leading to groin haematoma. Consequently, retroperitoneal access was performed for clamping the external iliac artery so as to control haemorrhage followed by explantation of the biosynthetic graft. An external iliac-popliteal above-knee bypass was tailored in order to save the limb and it was performed using a transobturator approach avoiding the infected site. In both cases bacterial cultures resulted positive for Morganella Morganii. The groin wound was treated separately with negative pressure medication healing definitively within 20 days and after 3-month follow-up the bypass was still patent. Conclusion This is the first report of biosynthetic graft infection used for infrainguinal reconstruction leading to haemorrhage due to anastomosis disrupture. Using an extra-anatomical access for providing blood inflow to the leg avoiding the infected site and treating safely the groin wound with VAC therapy revealed to be a valid approach.
