Overview

Acute mesenteric ischemia is caused in 50% of the cases by an embolism in the arterial mesenteric vasculature and in 30 % of the cases by a thrombus. 5% of the cases of acute mesenteric ischemia are caused by venous occlusion due to hypercoagulable state. In 20 to 30% of the cases, acute mesenteric ischemia is non occlusive and is rather caused by decreased systemic perfusion in the setting of an elderly patients with multiple co-morbidities and under treatment with medications that affect the effective circulatory volume such as diuretics.[1][2][3]

Causes

Occlusive Arterial Acute Mesenteric Ischemia (65-75%)

Occlusive Venous Acute Mesenteric Ischemia (5%)

Non Occlusive Mesenteric Ischemia (20-30%)
