Which body part of the patient is at risk for superior mesenteric artery syndrome?

What causes mesenteric ischemia and how to treat?
Treatment. If a blood clot causes a sudden loss of blood flow to the small intestine, you might require immediate surgery to treat your mesenteric ischemia. Mesenteric ischemia that develops over time might be treated with a procedure that uses a balloon to open the narrowed area. A mesh tube (stent) might be placed in the narrowed area.
