Abstract

Purpose: Endovascular aneurysm repair (EVAR) is used to treat abdominal aortic aneurysms (AAAs) with bilateral common iliac artery aneurysms (CIAAs), and an interruption of the bilateral internal iliac arteries (IIAs) is often needed, which may cause postoperative ischemic complications. An iliac branch device (IBD) has thus been introduced as an endovascular technique to preserve the IIA flow. This study aimed to evaluate the technical feasibility and short-term results of using an IBD when treating AAA with bilateral CIAAs in a Japanese institution, where IBD use has still not been approved by the government.

Methods: EVAR was performed using an IBD in six patients at high risk for open repair of an AAA with bilateral CIAAs.

Results: Advanta V12 stent grafts were successfully placed in the IIA, bridging between the IIA and the IBD side branch from the contralateral iliac artery. Subsequently, EVAR was performed as usual. The technical success rate was 100 %. At the most recent follow-up (mean follow-up period, 14.2 months), all IBDs were patent. No patients complained of buttock claudication or ischemic colitis.

Conclusions: The implantation of an IBD during EVAR is technically feasible in Japanese AAA patients with bilateral CIAAs, and may be a viable method to avoid pelvic ischemic complications, such as intractable buttock claudication.
