We report a case of a 43-year-old man who presented with gradually intensifying abdominal pain of acute onset and was shown by contrast-enhanced computed tomography (CT) examination to have acute aortic dissection (Stanford type B). A diagnosis of gastrointestinal necrosis was made and he underwent emergency surgery. At laparoscopy, he was found to have no superior mesenteric arterial pulse and intestinal necrosis from the upper jejunum to the right transverse colon. Resection of the superior mesenteric artery (SMA) perfusion area was performed. Postoperatively, ischemia in the perfusion area of the celiac artery was also diagnosed, manifesting as gallbladder necrosis, portal vein gas accompanying gastric wall necrosis, perforation of the remaining upper jejunum, and hepatic and splenic infarction. However, development of a collateral circulation originating in the left colic branch of the inferior mesenteric artery (IMA) enabled retrograde provision of blood to the celiac artery through the SMA pancreaticoduodenal arcade. Thus, in this case, spontaneous development of a natural bypass created a new route for arterial perfusion, contributing to the patient's survival. When ischemia of the celiac artery and SMA perfusion areas occur, collateral circulation can develop from the IMA.
