Treatment
Chronic mesenteric ischemia is usually treated with surgery. The narrow or blocked portion of the arteries may be removed and the arteries are then reconnected to the aorta. Or, the blocked part of the artery may be bypassed, with a piece of vein or a plastic tube. Acute mesenteric ischemia is treated with emergency surgery. It is extremely important to restore the blood supply to the intestine as quickly as possible by removing the blockage from the artery. Portions of the intestine may have to be removed if the lack of blood has caused any of the tissue to die.
Nonocclusive mesenteric ischemia is treated medically, while acute and chronic ischemia is correctable with surgery. The first step in treating nonocclusive ischemia is identifying the underlying cause and, once found, correcting it. For instance, if a patient is found to have vasospastic disease, direct injection of papaverine into the SMA may resolve the vasospasm. If resolution with papaverine occurs, start an infusion of 30-60 mg/h.
