Endovascular covered stent graft repair by through-and-through snaring of an acute traumatic femoral–femoral arteriovenous fistula following a gunshot wound

Abstract

Arteriovenous fistula (AVF) formation after penetrating injury underscores a rare and challenging complication of vascular trauma. Traumatic AVFs have various clinical presentations and reported methods of repair. Although open surgical repair is the most frequently used method of repair, the advancement of endovascular techniques has been increasingly used during the past 3 decades. We report a case of an acute traumatic AVF of the superficial femoral artery and superficial femoral vein from a gunshot wound repaired with a unique endovascular technique involving snaring to establish through-and-through access to allow deployment of a covered stent graft.
