title: Biliary leakage due to a rapidly growing post-traumatic hepatic artery pseudoaneurysm: a case report.
abstract: Post-traumatic hepatic pseudoaneurysms are rare. We report a very unusual case of bile duct injury complicated with an asymptomatic post-traumatic hepatic pseudoaneurysm. A previously healthy 17-year-old man sustained multiple traumas after a motorcycle accident. Post-traumatic hepatic pseudoaneurysms were detected after blunt liver injury. The rapid growth of the pseudoaneurysms in the hepatic hilus compressed the common hepatic bile duct and caused extrahepatic bile leakage at the lateral lobe. At first, the hepatic arterial pseudoaneurysms were embolized and bile leakage at the left lobe was treated conservatively. Finally, however, segment 2 and 3 partial liver resection should have been performed to stop the bile leakage. Post-traumatic pseudoaneurysm should be ruled out, in addition to the presence of biliary tract injury, if the intraperitoneal bile leakage appears after liver injury.
