Surgical repair of pseudoaneurysms and complex arteriovenous fistula between popliteal vessels

Abstract

An arteriovenous fistula (AVF) is an abnormal and permanent communication between an artery and a vein caused by penetrating traumas or iatrogenic injuries. A penetrating trauma to the endothelial wall can lead to formation of pseudoaneurysms (PSA) and to formation of an AVF. Here, the authors present the case of a patient with a complex AVF of popliteal vessels, associated with popliteal artery pseudoaneurysm, suggested by clinical features and imaging exams, and treated with conventional surgery due to unavailability of a stent graft with appropriate diameter and because endovascular surgery isn’t provided at the service where this patient was operated.
