Five-year outcomes from a prospective, multicenter study of endovascular repair of iliac artery aneurysms using an iliac branch device

The 5-year results of our prospective, multicenter study have confirmed the safety, efficacy, and durability of the IBE device for the treatment of aortoiliac and iliac artery aneurysms. The device effectively prevented common iliac artery aneurysm rupture, maintained the patency of the internal iliac artery, and avoided the complications associated with internal iliac artery sacrifice. Although common iliac artery aneurysm enlargement was rare, abdominal aortic enlargement was more common, suggesting that the outcomes of endovascular aneurysm repair might be different for patients with or without associated common iliac artery aneurysms.
