title: Aneurysmectomy and revascularization of a large hepatic artery aneurysm.
abstract: Aneurysms of the hepatic artery are rare, but are associated with significant mortality because of their lack of symptoms at presentation and risk of rupture. We report a case of an enlarging 4-cm hepatic artery aneurysm involving the proximal common hepatic artery to the bifurcation of the right and left hepatic arteries which was found incidentally on ultrasound examination. Endovascular treatment with a stent was considered, but because of the location of the aneurysm as well as the presence of significant thrombosis involving the right and left hepatic arteries, aneurysmectomy and revascularization using saphenous vein was performed. Doppler ultrasound measurements demonstrated good flow through the graft postoperatively and at 1-month follow-up. Although a variety of endovascular techniques exist to treat hepatic artery aneurysms, our results indicate that open excision and revascularization may be required and can have a good outcome.
