Hepatic artery-portal vein fistula detected on hepatic flow study: case report

A man with a history of gunshot wounds presented with jaundice and a bruit over the upper abdomen. The radionuclide flow sequence revealed simultaneous perfusion of the liver with transit of the activity down the aorta. The was considered compatible with a fistula between the hepatic artery artery and portal vein (confirmed angiographically and at autopsy).
