    Introduction: Despite significant outcome improvements seen after traumatic arterial limb injuries, they still remain a significant cause of limb loss and mortality. This study sought to identify predictors of mortality and major amputation for patients undergoing revascularization after femoropopliteal arterial trauma. Methods: This is a retrospective review of an institutional Vascular Trauma Registry from an urban trauma center in Brazil. All patients with an arterial femoropopliteal injury admitted to our hospital from November 2012 to December 2017 who underwent a vascular reconstruction were included. Univariate analyses followed by logistic regression analyses were performed to identify factors independently associated with the primary outcomes of amputation and mortality. Results: Ninety-six patients with vascular reconstructions were included. They had on average, 27 years old. The RTS was, on average, 7.152. The ISS was, on average, 15. 11 patients (11.5%) had amputation and 14 (14.6%) died. In the logistic regression model for amputation, was observed that patients with ischemia time greater than 6 hours presented approximately 10 times more chance of amputation than those with ischemia time equal or less than 6 hours (CI95%: 1,2 to 79,9). With each increase of one unit in the RTS, the chance of the patient having an amputation reduces 43% (CI95%: 2 a 96%). Logistic regression model for mortality, revealed that patients with ischemia time greater than 6 hours had approximately 6 times more chance of mortality than those with ischemia time equal to or less than 6 hours (CI95%: 1,26 to 24,77). Patients presented with hemodynamic instability were approximately 9 times more likely to die than those with hemodynamic stability (CI95%: 2,36 a 36,67). Each increase of one unit in the ISS, the chance of death increases by 14% (CI95%: 3 to 26%). Conclusion: Ischemic time, physiological status on admission and trauma scores are important risk factors to be considered in limb revascularization of patients with femoropopliteal arterial trauma. Local protocols must be established to guide the best treatment for these patients.

    Popliteal Artery Entrapment Syndrome: A Case Report and Review of the Literature

    Objective: Rare disease Background: Popliteal artery entrapment syndrome (PAES) results from an anomalous relationship between the popliteal artery and the myofascial structures of the popliteal fossa. The most common presenting symptoms include intermittent pain in the feet and calves on exercise, resulting in lameness. PAES can lead to popliteal artery thrombosis, stenosis, distal arterial thromboembolism, or arterial aneurysm. The treatment of PAES includes surgical exploration with fasciotomy, myotomy, or sectioning of fibrous band formation, to release the popliteal artery. However, in cases with thrombotic occlusion, thromboendarterectomy with venous patch arterioplasty, or venous graft arterial bypass surgery may be required. This report describes the presentation and surgical management of a case of PAES presenting with limb pain and includes a review of the literature on this condition. Case Report: A previously healthy 47-year-old woman presented with a 20-day history of sudden pain in the left lower limb, associated with pallor and a loss of arterial pulses below the knee. Angiography of the affected limb showed occlusion of the left supragenicular popliteal artery, with arterial occlusion, suggestive of arterial thrombus. Imaging of the right popliteal artery, which was not occluded, showed that it was medially deviated. An ipsilateral saphenous vein graft was used to bypass the left supragenicular popliteal artery to the infragenicular popliteal artery, resulting in resolution of the patient's symptoms. Conclusions: PAES is rare and can be under-diagnosed, possibly due to lack of knowledge of this condition. However, if the diagnosis is made early, the prognosis is usually favorable, following appropriate surgical treatment.
