title: Can the internal iliac artery be safely covered during endovascular repair of abdominal aortic and iliac artery aneurysms?
abstract: Aneurysmal involvement of the common iliac (CIA) or the internal iliac arteries (IIA) have been relative contraindications for safe endovascular aortic aneurysm (AAA) repair. Our goal was to review our experience in dealing with this problem by performing permanent coverage of one or both IIA during endoluminal repair of aneurysms of the aortoiliac region and to develop a safe, durable strategy. Of the 228 consecutive patients who had endoluminal repair of abdominal aortic (AAA) and iliac artery (IAA) aneurysms between 4/1999 and 4/2001 at our institution, 49 patients underwent coverage and/or coil embolization of one or both IIA during repair because of complex aortoiliac anatomy. These patients were evaluated prospectively for short-term adverse outcome. The results showed that CIA or IIA aneurysms can be managed safely during endoluminal repair of AAA. The IIA can be covered or embolized with minimum adverse consequences in patients who have inadequate CIA for deployment of the aortic or iliac endograft. Unilateral IIA occlusion is well tolerated. We advocate that whenever bilateral IIA occlusion is necessary during endovascular aneurysm repair, one of the IIAs should be revascularized if it is not aneurysmal.
