Mesenteric Ischemia
(redirected from Bowel ischemia)

   Also found in: Wikipedia 0.01 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

Mesenteric ischemia Acute small bowel ischemia can result from occlusive (arterial or venous) causes as well as nonocclusive causes, such as hypoperfusion.
