Abstract
Rupture of a hepatic artery aneurysm into the biliary tree is a rare cause of hemobilia. The dramatic nature of the disease and the difficulties in obtaining a preoperative diagnosis are the main causes of its high mortality rate. Progress in vascular radiology and surgery seems to be an important factor in improving the survival rates in patients with this type of hemobilia. A case of a patient with an aneurysm of the common hepatic artery ruptured into the common bile duct is reported. Preoperative arteriography revealed the aneurysm and the arteriobiliary fistula causing massive hemobilia. The patient was successfully treated by arterial ligation and is symptom free after 2 years.
