A Case of Ruptured PancreaticoduodenalAneurysm / 日本農村医学会雑誌

ABSTRACT

　　Among visceral artery aneurysms, those arising in the region of the pancreatic duodenal artery due to celiac artery stenosis are rare. We report a surgical case with stenosis caused by dissecting celiac artery aneurysms and multiple aortic aneurysm rupture in the pancreaticoduodenal region. A 72-year-old man with a history of distal gastrectomy for gastric cancer was carried into our hospital by ambulance for acute abdominal pain. CT scans showed dissected aneurysms of the root of the celiac artery and hepatic artery as well as massive retroperitoneal hematoma around the pancreaticoduodenum and intraperitoneal hemorrhage. Arteriography of the superior mesenteric artery revealed multiple aneurysms of the pancreaticoduodenal artery that might have caused rupture. In the late phase, retrograde flows in the gastroduodenal, hepatic, celiac, and splenic arteries from the pancreaticoduodenal artery were contrast-enhanced. Because it was thought that transcatheter arterial embolization or surgical aneurysmectomy for pancreaticoduodenal aneurysms could prevent blood flow in all circulating branch arteries of the celiac artery, leading to extensive organ ischemia, the gastric pouch, spleen, entire pancreas, and gallbladder were resected. The patient has been doing well.
