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).

TAE was achieved by filling the entire artery and pseudoaneurysm with coils of 3 and 4 mm (Figure 2). The patient had an uneventful clinical course without rebleeding, and the NBD was removed and started oral intake.
