Hematobilia from ruptured hepatic artery aneurysm. Report of two cases.

Hematobilia secondary to hepatic artery aneurysm must be considered in the differential diagnosis of unexplained gastrointestinal tract hemorrhage. We treated two patients with ruptured hepatic artery aneurysm. One had hepatic artery aneurysm proximal to the gastroduodenal artery; the other had an intrahepatic pseudoaneurysm in the right lobe of the liver. The first patient was treated with obliterative endoaneurysmorrhaphy. The second required ligation of feeding vessels, cholecystectomy, and reconstruction of cholecystoduodenal fistula.
