Rupture of a pseudoaneurysm (PA) has been reported as a rare but serious adverse event associated with endoscopic biliary stenting. We herein report 2 cases of severe biliary bleeding from a PA that developed 10-14 days after placement of a self-expandable metallic stent (SEMS) for biliary malignancy. The first patient was successfully embolized with endovascular coiling. However, the second patient had wide-spreading cholangiocarcinoma and, despite being treated once by full coiling, developed a second rupture of PA two months after starting systemic chemotherapy. Clinicians should be aware of the possibility of PA and carefully follow stented patients after endovascular treatment.
