Immediate endovascular treatment of an aortoiliac aneurysm ruptured into the inferior vena cava

Abstract

An aortocaval fistula is a severe complication of an aortoiliac aneurysm, usually associated with high perioperative morbidity and mortality during open operative repair. We describe the successful endovascular treatment of a symptomatic infrarenal aortic aneurysm ruptured into the inferior vena cava with secondary interventional coiling of a persistent type II endoleak because of retrograde perfusion of the inferior mesenteric artery. Endovascular exclusion of ruptured abdominal aneurysms seems to be a valuable treatment option for selected patients even with complicated vascular conditions like an aortocaval fistula.
