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.
