Hepatic artery aneurysm in a patient with hepatitis C liver cirrhosis: report of a case

Visceral artery aneurysms are rare, with an incidence rate of only 0.01–0.2 % in routine autopsies, and hepatic artery aneurysms account for approximately 20 % of these aneurysms. Despite recent advances in therapeutic techniques and diagnostic tools, the management of visceral artery aneurysms remains clinically challenging. We report a case of hepatic artery aneurysm with liver cirrhosis due to hepatitis C in an 81-year-old woman. A computed tomography scan demonstrated a hepatic artery aneurysm 4.4 cm in diameter. She underwent successful aneurysmectomy with vascular anastomosis. A computed tomography scan on postoperative day 7 demonstrated patent hepatic artery. The patient was followed-up for 1 year after surgery and died owing to progressive liver failure. However, she did not show any hepatic artery problem such as hepatic arterial thrombosis or occlusion. We discuss the risk factors of atherosclerosis in patients with liver cirrhosis, and present an overview of the treatment of hepatic artery aneurysms.
