Hepatic Artery Aneurysm

Antonios P Gasparis, MD, L Philipp Wall, MD, John J Ricotta, MD

A 62 -year female was found to have an incidental hepatic artery aneurysm on CT scan (Fig 1).  She was asymptomatic and the aneurysm measured 2.2 cm in size and appeared to be located at the bifurcation of the common hepatic artery.

A mesenteric angiogram was obtained to determine the exact location of the aneurysm and decide if she was a candidate for endoluminal repair.  The angiogram (Fig 2) confirmed the location of the aneurysm at the hepatic artery bifurcation with no other visceral aneurysms.

Open surgical repair was performed with resection of the aneurysm and placement of a bifurcated segment of saphenous vein (Fig 3) to revascularize the proper hepatic and gastroduodenal arteries.
