Bilateral Implantation of Double-Branched Iliac Branch Devices for Endovascular Repair of Aorto-Bi-Iliac Aneurysm With Concomitant Hypogastric Aneurysms: The Quadruple Branch.

PURPOSE: The purpose of this report is to describe the use of a double-branched custom-made iliac branch device (IBD) for the endovascular repair of an aorto-bi-iliac aneurysm with concomitant bilateral hypogastric aneurysms. TECHNIQUE: A 61-year-old man on peritoneal dialysis underwent a computed tomography (CT) of the infrarenal aorta before planned kidney transplantation. The CT showed an asymptomatic aorto-bi-iliac aneurysm of 54 mm involving the hypogastric artery (HA) bilaterally (right HA 31 mm; left HA 40 mm). The treatment consisted of an endovascular aortic repair (EVAR) and the bilateral implantation of custom-manufactured IBDs with double inner branches to preserve both superior and inferior gluteal arteries. At 1 year follow-up, the patient remains free of symptoms and the postoperative CT showed a successfully excluded aneurysm with patent bridging stent grafts to all HA branches. CONCLUSION: The bilateral implantation of double-branched IBDs is a feasible technique. Preservation of both hypogastric arteries and its branches can be achieved with this technique and therefore decrease the risk of buttock claudication and other ischemic complications.
