Abstract
The advent of endovascular technology for treating aortoiliac aneurysms has sometimes necessitated the occlusion of the hypogastric artery to prevent an endoleak or to achieve an adequate distal seal, resulting in significant morbidity for some patients. The use of iliac branch devices, in conjunction with aortic stent grafts, has made it possible to preserve the hypogastric arteries in select patients with suitable anatomy. The purpose of this review will be to discuss the indications for hypogastric preservation during treatment of aortoiliac aneurysms, as well as highlight the key procedural steps and potential technical challenges encountered during this procedure.
