 A 59-year-old male patient with cholangiocarcinoma on dialysis experiened bleeding on postoperative day 28. The patient had no evidence of pancreatic or biliary leakage. a: Pseudoaneurysm at the GDA transection (⇧). b: The GDA pseudoaneurysm was identified, and the position of the Viabahn stent graft was adjusted (white arrow). c: Viabahn stent graft was expanded, and hemostasis was completed (black arrow). The next day, the patient was found to be hypotensive and hemorrhagic, and another angiogram was performed because rebleeding was suspected on enhanced CT. d: The GDA pseudoaneurysm that had not been visualized the previous day was again contrasted, and a guidewire strayed into the pseudoaneurysm from the side of the Viabahn stent graft (⇧). e: The n-butyl-2-cyanoacrylate (NBCA) and lipiodol mixture was injected into the aneurysm, and the Viabahn stent graft was further balloon-dilated and compressed (white arrow). f: Hemostasis was achieved without compromising hepatic blood flow (black arrow). Abbreviation: GDA, gastroduodenal artery
