Mesenteric Ischemia

   Also found in: Wikipedia 0.02 sec.
mesenteric ischemia,
ischemia in an area of the intestine supplied by a mesenteric artery. Two types are distinguished, occlusive and nonocclusive mesenteric ischemia. It may progress to a mesenteric infarction.

Abdominal Angina
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
Management Bypass, endarterectomy, vascular reimplantation, percutaneous transluminal angioplasty

Twenty-five brief case studies narrate the history, symptoms, and diagnosis of patients suffering from abdominal aortic aneurysm, temporal arteritis, chronic mesenteric ischemia, pericardial tamponade, oncologic cardiomyopathy, brugada syndrome, and pulmonary embolism.
Mortality of patients with renal ischemia is reported to be 50 to 70% and mortality figures in mesenteric ischemia can be as high as 87% (8, 9).
To the Editor: Acute mesenteric ischemia occurs in 1 of 1000 hospital admissions, and a nonocclusive mechanism makes up about 20% of these cases.
