Transcatheter Arterial Embolization of Ruptured Inferior Phrenic Artery Pseudoaneurysm Following Completion Gastrectomy

A 56-year-old man underwent completion gastrectomy and regional lymphadenectomy for adenocarcinoma of the remnant stomach. Postoperatively, he developed an esophagojejunal anastomotic insufficiency associated with leakage of activated pancreatic juice, resulting in pseudoaneurysm arising from the inferior phrenic artery (IPA) with massive bleeding. Emergency angiography was performed, and the artery was successfully embolized using N-butyl cyanoacrylate. Pseudoaneurysm of the IPA is an extremely rare entity, and transcatheter arterial embolization is an effective treatment method because of its advantages over surgery.
