Giant Bilobed Hepatic Artery Aneurysm with Occlusion of the Celiac Axis: Repair Using a Bifurcated Graft.

Hepatic artery aneurysms are uncommon, with fewer than 500 cases noted in the literature. Bilobed hepatic artery aneurysms are extremely rare, with no documented cases in the literature. Although often asymptomatic, these visceral aneurysms are at high risk of rupture. We present an interesting case report of a bilobed hepatic artery aneurysm with occlusion of the celiac axis in a 72-year-old woman. She was asymptomatic at the time of presentation, and diagnosis was made on computerized tomography scan. She was not a candidate for endovascular repair due to the anatomy of the aneurysm and a chronically occluded celiac artery origin. Surgical repair using a bifurcated graft with ligation of the gastroduodenal artery was performed.
