Transcatheter Embolization of Celiac Artery Pseudoaneurysm following Pancreaticoduodenectomy for Pancreatic Cancer

Abstract

A case of transcatheter embolization of a celiac artery pseudoaneurysm in a 70-year-old man is reported. the pseudoaneurysm was considered to be the result of pancreatic anastomotic leakage and an intra-abdominal abscess following pancreaticoduodenectomy with irradiation of 66 Gy for pancreatic carcinoma. To avoid recanalization of the pseudoaneurysm due to retrograde blood flow, first all branches of the celiac artery were embolized with metallic coils, and then the celiac trunk was also occluded. Hepatic arterial flow was preserved by the right hepatic artery arising from the superior mesenteric artery. After the procedure, the patient had no noticeable complications associated with the embolization nor any recurrence of the pancreatic cancer, and he achieved a 2-year survival.
