Mesenteric Venous Thrombosis

Mesenteric venous thrombosis usually involves the superior mesenteric vein, with the danger of bowel infarction. The newer imaging techniques allow earlier diagnosis. A predisposing condition (such as a prothrombotic state, pancreatitis, and recent abdominal surgery) can be identified in most patients. Treatment involves anticoagulation, and surgery may be avoided if the correct diagnosis is made early.
