title: The midterm experience of tapered stent grafts in the endovascular management of iliac artery aneurysms with unfavorable anatomy.
abstract: We report our experience and the midterm results of a modern technique for endovascular management of isolated iliac artery aneurysms (IAAs) with unfavorable neck anatomy, which involves the inversion of an iliac leg of a Zenith stent graft. Patients who underwent endovascular IAA repair from 2002 to 2010 were reviewed. A total of 12 patients, with a mean age of 77.6 years, underwent endovascular repair of 13 IAAs. Mean size of the aneurysms was 54.6 mm (range 34-133 mm). Mean proximal neck diameter was 18 mm (range 15-22 mm). In 7 patients, the length of the proximal neck was <15 mm (10-14 mm). Only 1 patient developed thrombosis of the stent graft immediately after the operation. Patients were followed up for a mean of 31.5 months (range 18-72 months). Our midterm results demonstrate the durability of this technique in the management of iliac aneurysms with unfavorable anatomy.
