title: Preservation of pelvic circulation in one-stage endovascular repair of bilateral hypogastric artery aneurysms.
abstract: Bilateral hypogastric artery aneurysms (HAAs) are relatively rare conditions that pose increased management difficulties. We report a case of one-stage endovascular repair of bilateral HAAs preserving pelvic circulation. A 67-year-old asymptomatic man with bilateral HAAs (4-cm right and 3.9-cm left) was successfully treated with an endovascular approach. The aneurysmal sac of the right hypogastric artery (HA) was embolized first and 2 covered stent grafts were deployed into the HA. Coil embolization of the left HAA was then performed followed by deployment of a covered stent graft to the common and external iliac arteries. Final angiography revealed complete exclusion of the aneurysms without endoleaks and with preservation of the pelvic flow. At the 18-month follow-up, the patient remained asymptomatic with good patency of the stent grafts. This case demonstrates an alternative endovascular approach for the treatment of bilateral HAAs that minimizes the risk of ischemic complications by preserving pelvic circulation.
