The pain is dull, crampy, epigastric, usually beginning within an hour after eating, lasting about two hours. He has tried famotidine and pantoprazole without any relief. It is worse with ice cream, french fries, and fried chicken. Review of systems notes nausea, vomiting, early satiety, and weight loss. The patient is worried about cancer. Exam reveals a cachectic man with an abdominal bruit, but is otherwise unremarkable. There is no tenderness or pain to palpation. Routine laboratory tests, chest and abdominal radiographs, endoscopy, and colonoscopy are all negative. Lateral angiogram and angiogram with contrast injected into the inferior mesenteric artery are shown below.

Chronic mesenteric ischemia is intestinal hypoperfusion, usually from mesenteric atherosclerotic disease, unlike acute mesenteric ischemia which occurs due to occlusion of arterial or venous blood flow. The images show thrombosis of the SMA (arrowhead) and stenosis of the CA (arrow) as well as collateral vessels from the marginal artery of Drummond (second image).
