Treatment results of the acute intestinal ischemia in 72 patients were analyzed. Patients aged 69.2±5.8 years. Occlusive vascular lesions of the intestinal vessels (thrombosis and embolism of the superior mesenteric artery and thrombosis of the superior mesenteric vein) were obliged to the ischemic disorders in 84.5% of patients. The rest 15.5% of patients demonstrated microvascular disorders (nonocclusive ischemia). The issue presents the novel algorithm for treatment and diagnostics of the acute intestinal ischemia.
