Hepatic artery pseudoaneurysm presented with haemobilia: Rare complication of plastic biliary stent insertion

Abstract

A 45-year-old man was admitted with Obstructive jaundice. A plastic stent was placed in CBD to relieve obstructive cholangitis. Two weeks after the procedure, the patient was readmitted with cholangitis caused by hemobilia. However, USG abdomen, computed tomography (CT), endoscopic retrograde cholangiopancreatography (ERCP) failed to establish the bleeding source. Later Abdominal angiography revealed a hepatic artery pseudoaneurysm for which embolization done with Inj. Glue therapy and bleeding was stopped. Hemobilia after plastic stent placement is extremely rare. We urge Gastroenterologists to consider the possibility of a pseudoaneurysm near the stent when trying to identify the bleeding source.
