Open Surgical Repair for a Giant Common Hepatic Artery Aneurysm with Difficulty in Proximal Arterial Clamping: A Case Report

摘要

Hepatic artery aneurysm has been considered as a rare, life-threatening disease. In this study, we report on a patient requiring surgical treatment for a giant hepatic artery aneurysm by aneurysmectomy without revascularization. A 70-year-old woman who complained of epigastric pain was referred to our hospital. Enhanced computed tomography scan has revealed a giant (11×9 cm) common hepatic artery aneurysm. She then underwent emergency surgery; the intra-aortic balloon occlusion technique was applied in order to control the blood inflow into the aneurysm. The aneurysm was then incised, and direct closure of the inflow and outflow orifices was performed safely without evidence of ischemic change in the liver.
