Evaluation of portal vein thrombosis in liver graft ten years after liver transplantation due to budd-Chiari syndrome using Doppler ultrasound.

Budd-Chiari syndrome is a rare but life-threatening disorder characterized by obstruction of the hepatic venous outflow. Treatment depends on underlying cause, extent of the obstruction and functional capacity of the liver. When all other therapy options are unsuccessful, liver transplant should be considered. Portal vein thrombosis (PVT) is a frequent event in patients with cirrhosis which can be treated with anticoagulants, but there are limited data regarding safety and efficacy of this approach.
