Abstract

We present three cases of pseudoaneurysm caused by self-expandable metal stents that formed arteriobiliary fistulas and caused hemobilia. Diagnoses were made on the basis of dynamic computed tomography or angiography. One patient died because of bleeding and cholangitis, whereas the others were successfully treated by transarterial embolization.
