Embolism mesenteric arteries occurs normally in patients with atherosclerosis, myocardial infarction, rheumatic heart disease and hypertension, periarteritis nodosa, vasculitis, endarteritis, and cancer. More rarely occlusion of mesentericarteries is due to thrombosis or embolism of a massive abdominal aorta and its dissecting aneurysm.
Mesenteric vein thrombosis often occurs in patients with intestinal infections, malignancies, liver cirrhosis, splenomegaly, with cardiac decompensation after surgery.
