Current endovascular treatments for isolated iliac artery aneurysms (IIAAs) include the use of aortoiliac stent grafts with coverage of the distal aorta or stent grafts confined to the iliac artery without active proximal fixation. We report our experience in the use of custom-made Cook Zenith(TM) iliac limb stent grafts with proximal barb fixation. Patients treated from July 2009 to February 2011 were included. All imaging and patient records were assessed for perioperative and early outcomes. Nine IIAAs (seven patients) were treated. The mean patient age was 80 years (range 58-91 years). The mean aneurysm size was 48 mm (35-80 mm), and the mean length of the proximal landing zone (PLZ) was 29 mm (10-50 mm). The distal landing zone was in the external iliac artery after coil embolization of the internal iliac artery. The Mean diameter of the PLZ was 21 mm (20-24 mm). Technical success was achieved in eight cases. Perioperative complications included reoperation in one patient for groin bleeding and ischemia. On follow-up (mean 12 months, range 1-26), all aneurysms were successfully excluded from the circulation and there was no stent graft migration or thrombosis. Use of custom-made stent grafts with proximal barb fixation in treatment of IIAAs is a feasible option which may reduce the risk of migration when compared with stent grafts with lack of proximal fixation.
