To evaluate the safety and efficacy of stent-graft coverage of the hypogastric artery origin without coil embolization during endovascular treatment of aortoiliac or iliac aneurysms.


A retrospective study was conducted of patients who underwent endovascular aneurysm repair with endograft coverage of the hypogastric artery between September 2001 and September 2005. Among the 88 patients who underwent EVAR during the study period, 21 patients (19 men; mean age 77+/-6 years, range 67-86) had unilateral hypogastric artery coverage without coil embolization. Aneurysmal arteries included 11 aortoiliac, 8 isolated common iliac arteries (CIA), and 2 isolated hypogastric arteries. Preoperative AAA size was a mean 57 mm (range 46-73), and mean CIA aneurysm diameter was 36 mm (range 17-50). All covered hypogastric arteries were patent prior to the procedure. The stent-grafts implanted were 10 Excluder, 10 AneuRx, and 1 Zenith. Clinical outcome focused on mortality and morbidity, including the occurrence and duration of new-onset buttock claudication, which was further correlated with superior gluteal and profunda femoris artery patency.


Immediate seal was achieved in all patients. Mean follow-up was 16 months (range 1-54). No type I endoleaks developed from the aortic or external iliac artery, and no type II endoleaks were found from the origin of the hypogastric artery. New-onset buttock claudication occurred in 2 (9.5%) patients, but resolved in both within 4 months. No additional secondary procedures, aneurysm rupture, or aneurysm-related death occurred.


Stent-graft coverage of the orifice of the hypogastric artery without coil embolization is a safe and effective adjunct during the treatment of aortoiliac or iliac aneurysm, with a low incidence of buttock claudication.
