Mesenteric Venous Thrombosis

Mesenteric venous thrombosis is thrombosis of mesenteric veins (SMV/portal), due to hypercoagulability, portal hypertension, abdominal inflammation, or malignancy, causing abdominal pain and possible bowel infarction. Treatment: anticoagulation (LMWH/warfarin/DOAC); NPO; IV fluids; antibiotics; surgical exploration/resection if bowel necrosis; treat underlying hypercoagulability; thrombolysis in selected; monitor for recurrence/bleeding; follow-up imaging.

Common Symptoms

Causes and Pathogenesis

Hypercoagulability causes mesenteric venous thrombosis and congestion/ischemia.

Treatment

Anticoagulation; supportive care; surgery if necrotic; treat hypercoagulability

Preventive Measures
