After the failure of endoscopic retrograde cholangiopancreatography, endoscopic ultrasound\u2010guided hepaticogastrostomy (EUS\u2010HGS) was performed with a 7\u2010Fr plastic stent (PS) into the B2 bile duct. Three months later, mild bleeding was observed during stent exchange, but was stopped by stent replacement. The patient developed recurrent cholangitis, and 1 month later, when the PS was removed to add supplementary drainage, massive bleeding occurred from the endosonographically created route into the stomach. Contrast\u2010enhanced computed tomography (CECT) revealed a pseudoaneurysm in the A2 branch of the hepatic artery. Emergency angiography confirmed active extravasation, and successful transcatheter arterial embolization with\n                    <jats:italic>N<\/jats:italic>\n                    \u2010butyl\u20102\u2010cyanoacrylate was performed. The patient recovered without rebleeding but died two weeks later from worsening interstitial pneumonia. A review of publications identified only three previous cases of pseudoaneurysm after EUS\u2010HGS, all of which involved self\u2010expandable metal stents. This case demonstrates that pseudoaneurysms can cause both gastrointestinal bleeding and recurrent cholangitis. Careful evaluation of CECT images is needed before stent manipulation in patients with biliary symptoms after EUS\u2010HGS.\n
