Causes of Acute Mesenteric Ischemia
Occlusion Type | Risk Factors |
|---|---|
Arterial embolus (> 40%) | Coronary artery disease, heart failure, valvular heart disease, atrial fibrillation, history of arterial emboli |
Arterial thrombosis (30%) | Generalized atherosclerosis |
Venous thrombosis (15%) | Hypercoagulable states, inflammatory conditions (eg, pancreatitis, diverticulitis), trauma, heart failure, renal failure, portal hypertension, decompression sickness |
Nonocclusive ischemia (15%) | Low-flow states (eg, heart failure, shock, cardiopulmonary bypass), splanchnic vasoconstriction (eg, vasopressors, cocaine) |
