Abstract
A case of hemobilia due to a hepatic artery aneurysm is described. Despite 2 arteriograms and 2 laparotomies, the cause of the bleeding remained undetected until a further selective cannulation of the celiac axis artery was performed. Endoscopic retrograde cholangiography demonstrated that postoperative jaundice was not due to obstruction and outlined the aneurysm within a hepatic duct.
