ABSTRACT
The chronic form of mesenteric ischemia is often less demanding of thought and action. It usually occurs in patients who have a history of atherosclerotic vascular disease and present with intermittent or progressive abdominal symptoms, frequently described as abdominal angina, which produces postprandial abdominal cramps or pain. Nonocclusive mesenteric ischemia can be equally as fatal because it generally occurs in very ill patients who are hemodynamically stressed and are compromised by decreased visceral perfusion superimposed upon diffuse atherosclerosis.100
