ABSTRACT

Self-expandable metallic stent (SEMS) has been widely used for internal drainage of malignant biliary stricture. SEMS placement was considered relatively safe. However, complications, such as cholangitis, pancreatitis, bleeding, perforation, and stent migration, were occasionally observed. Especially hepatic artery pseudoaneurysm after endoscopic balloon dilatation in stenosis of SEMS had not been reported. We experienced the case that patient of hepatic artery pseudoaneurysm after endoscopic balloon dilatation in stenosis of metallic stent for Klatskin tumor and was treated by transcatheter arterial embolization. Therefore, we report this case with literature review.
