Figure 6 Transcatheter arterial embolization performed on the 12th hospital day. A, B: On angiography, the left and right hepatic arteries were found to arise from the superior mesenteric artery, and the pseudoaneurysm was confirmed to be located in the right hepatic artery; C: One IDC coil was placed in the right hepatic artery on the distal side of the pseudoaneurysm (arrow) after the pseudoaneurysm was framed using several types of coils. Seven coils were placed in the right hepatic artery on the distal and proximal sides of the pseudoaneurysm using the isolation method.
