Endovascular Treatment of Common Iliac Artery Aneurysms Using the Bell-Bottom Technique: Long-term Results

Purpose: To retrospectively evaluate the long-term outcome of the bell-bottom technique for the endovascular repair of common iliac artery (CIA) aneurysms. Methods: Between September 2003 and September 2008, 89 patients (84 men; mean age 73.7±8.4 years) with aortic and CIA aneurysms were treated at 2 European centers with aortic extension cuffs or large iliac limbs that gave a bell-bottom configuration to the iliac portion of an aortoiliac stent-graft. The mean maximum aortic diameter was 65.7±12.3 mm (range 42–98), and the mean diameter of the treated CIA aneurysms was 22.1±3.0 mm (range 20–30). Results: Technical success was achieved in 97.8% (87/89). There was no early (
