A Case of Intra-abdominal Bleeding from a Posterior Superior Pancreaticoduodenal Artery Aneurysm following Total Gastrectomy Treated by Transcatheter Arterial Embolization

Abstract

A case of intra-abdominal bleeding from a posterior superior pancreaticoduodenal artery (PSPDA) aneurysm following total gastrectomy for gastric cancer treated by transcatheter arterial embolization (TAE) is reported. Hemostasis was achieved by embolization to the gastroduodenal artery (GDA), anterior inferior pancreaticoduodenal artery (AIPDA), and posterior inferior pancreaticoduodenal artery (PIPDA). Although the primary blood supply of the head of the pancreas from both the celiac artery and the superior mesenteric artery was blocked by TAE, ischemic necrosis of the pancreas and other complications did not occur.
A communicating artery such as the dorsal pancreatic artery from the splenic artery was thought to supply arterial blood flow to this region.
