Hepatic Artery Aneurysm-A Rare Cause of Cholestasis.

Abstract

Hepatic artery aneurysms (HAAs) are rare vascular malformations that can arise from atherosclerosis, trauma, or iatrogenic injury. HAAs can be symptomatic and lead to serious complications. We present the case of a patient with painless jaundice caused by obstruction of the distal common bile duct by a HAA on a replaced right hepatic artery. This was further complicated with cholangitis. After endovascular stenting of the aneurysm, cholestasis decreased. Learning point: Hepatic artery aneurysms can cause common bile duct obstruction resulting in cholestasis.
