Severe Hemobilia from Hepatic Artery Pseudoaneurysm
Figure 1
The angiogram shows the sac of a 2 cm pseudoaneurysm, with no radiologic evidence of arterobiliary fistula. A few days before, the CT scan revealed a vascular lesion of 4 mm, successively enlarging to the size reached at the moment of bleeding (smaller arrow). The pseudoaneurysm was located on a replaced right hepatic artery branching off the superior mesenteric artery (greater arrow).
