Budd-Chiari syndrome (BCS) is an obstruction of hepatic venous flow at any level, from small hepatic veins to the junction of the inferior cava vein and the right atrium. Studies report that BCS is associated with prothrombosis. The authors present a review of the topic based on a case report of BCS where several risk factors are involved. These factors were genetic, such as mutation of the plasminogen activator inhibitor with 4G polymorphism and acquired, such as ulcerative colitis and oral contraceptives.
