chronic mesenteric ischemia


Also found in: Wikipedia.
A condition characterised by intermittent severe ischaemia, resulting in abdominal colic, beginning 15–30 mins post-prandially, lasting 1–2 hours, and appearing when 2 or all 3—superior and inferior mesenteric and celiac—major abdominal arteries have severe atherosclerosis; because the intestine’s O2 demand increases with meals, patients avoid the pain by not eating, and thus lose weight; malabsorption may occur since absorption is O2-dependent

chronic mesenteric ischemia

Abdominal angina A condition characterized by intermittent severe ischemia, resulting in abdominal colic, beginning 15-30 mins post-prandially, lasting 1-2 hrs, and appearing when 2 or all 3–superior and inferior mesenteric and celiac major abdominal arteries have severe ASHD; since the intestine's O2 demand ↑ with meals, Pts avoid the pain by not eating, and thus lose weight; malabsorption may occur because absorption is O2-dependent Management Bypass, endarterectomy, vascular reimplantation, percutaneous transluminal angioplasty

Chronic mesenteric ischemia is also known as "intestinal angina" and results from inadequate blood flow to the bowel, typically in the setting of underlying atherosclerotic disease in elderly patients causing significant occlusion or narrowing of the celiac axis, SMA, and/or inferior mesenteric artery.
Chronic mesenteric ischemia results in a characteristic clinical syndrome of chronic abdominal pain, especially after meals, and is frequently associated with weight loss.
