Endovascular repair of bilateral iliac artery aneurysm with branched iliac stents: case report and review of the current literature.

Abstract

Common iliac artery aneurysm (CIA) often occurs in conjunction with an abdominal aortic aneurysm (AAA), which extends into one or both CIAs in 20% to 30% of patients. Conventional endovascular treatment includes coil embolization of the internal iliac artery (IIA), followed by extension of the main bifurcated AAA stent-graft into the external iliac artery. However, complications from intentional occlusion of unilateral or bilateral IIAs are frequent and sometimes serious. Several methods try to preserve the unilateral or bilateral IIA. Here we report a case of concomitant bilateral CIA and AAA successfully treated with bilateral branched iliac stent-grafts.
