Portal-vein Thrombosis

Portal-vein thrombosis is thrombus in the portal vein, associated with cirrhosis, abdominal malignancy, abdominal inflammation (pancreatitis), or hypercoagulable states. Clinical: abdominal pain, portal hypertension, bowel ischemia (acute), or incidental finding (chronic). Treatment: anticoagulation; treat underlying cause (cirrhosis/malignancy/infection); endovascular recanalization/TIPS for symptomatic chronic; manage portal-hypertension complications; avoid anticoagulation in variceal bleeding until controlled.

Treatment

Anticoagulation; treat cause; recanalization/TIPS for symptomatic chronic; manage portal HTN

Preventive Measures
