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.
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

chronic mesenteric ischaemia

A condition characterised by intermittent severe ischaemia resulting in abdominal colic, beginning 15–30 minutes post-prandially and lasting 1-2 hours, which appears when 2 or all 3 of the superior and inferior mesenteric and coeliac major abdominal arteries have severe atherosclerosis. Because the intestine’s O2 demand increases with meals, patients may avoid the pain by not eating, thus losing weight. Malabsorption may occur because absorption is O2-dependent.

Popularly known as abdominal angina, chronic mesenteric ischaemia is preferred by journals that use British English, while chronic intestinal ischemia is used in journals that publish in American English.
 
Management
Bypass, endarterectomy, vascular reimplantation, percutaneous transluminal angioplasty.
