Causes of acute mesenteric ischemia: acute mesenteric thrombus (usually in
presence of atherosclerotic lesion); acute embolus ( source such as cardiac);
nonocclusive mesenteric arterial ischemia (as in decreased cardiac output due to congestive heart failure on digoxin and as in cocaine overdose with spasm);
acute mesenteric venous thrombosis (usually longer duration of symptoms prior
to presentation).
