Two cases of endovascular abdominal aortic aneurysm repair with iliac aneurysm using a zenith iliac bifurcation graft.

We report on treatment of an abdominal aortic aneurysm with common iliac artery aneurysm using an iliac branch device. We performed 2 cases because of a large common iliac artery aneurysm or a complication of an internal iliac artery aneurysm. Both cases had a good postoperative course and progressed without embolizing the iliac branch device during follow-up period. Though there is a drawback, it is not covered by the national insurance program in Japan and cannot be used in all applicable cases. However, use of a unilateral or bilateral iliac branch device allows us to maintain the bloodstream of the internal iliac artery, thus suggesting it to be effective in such cases.
