Causes of Mesenteric Ischemia • Arterial Occlusion (~50% of cases) • Emboli to SMA due to atrial fibrillation or mural thrombi due to cardiac hypokinesia • Thrombotic occlusion due to pre-existing atherosclerotic vessel disease or acute obstruction with underlying chronic mesenteric ischemia • Cardiac valvular lesions/vegetations • Atheroemboli • Dissecting aortic aneurysm • Fibromuscular dyplasia • Trauma • Endotoxin induced shock
