Pathophysiologic findings of nonocclusive mesenteric ischemia

Pathophysiologic findings of nonocclusive mesenteric ischemia (NOMI) 

NOMI occurs, as the name implies, without the presence of an embolus or thrombus.

The risk of intestinal hypoperfusion can increase with shock, severe hypovolemia, decreased cardiac output, and during major thoracic or abdominal surgery as the mesenteric vasculature vasoconstricts.

It can also be seen in patients taking digoxin or cocaine as these aggravate mesenteric vasoconstriction.
