Impending Rupture of a Common Hepatic Artery Aneurysm Successfully Treated by Emergency Coil Embolization: A Case Report

Abstract

Although hepatic artery aneurysms are rare, rupture of a hepatic artery aneurysm frequently has serious consequences; therefore, these aneurysms should ideally be treated before rupture. Herein, we report a case in which we successfully performed coil embolization in a patient with impending rupture of a common hepatic artery aneurysm. A 70–year–old woman presented with a 1–day history of progressive upper abdominal and back pain. Enhanced computed tomography of the abdomen revealed a 16–mm saccular aneurysm in the common hepatic artery and features consistent with impending rupture of the aneurysm. We immediately performed endovascular coil embolization. During the procedure, we preserved the gastroduodenal and celiac arteries to preserve collateral blood flow to areas distal to the embolized artery. The patient’s symptoms disappeared one day after the procedure, and she was discharged on the day. She was still doing well at the 6–month follow–up.
