[Clinical study of expandable venous stents for treatment of Budd-Chiari syndrome].

Expandable venous stents is a new method for treatment of Budd-Chiari syndrome (BCS). Ten cases of BCS underwent expandable venous stents in inferior cava vein or/and in hepatic vein, or/and intrahepatic portosystemic shunt according to the location and the extent of lesion. Expandable venous stents were successful in all patients. No serious procedure-related complications were observed. The symptoms and signs disappeared. Portal pressure and inferior cava vein pressure gradient reduced immediately after treatment. The blood in stents flowed quickly. During follow-up of 1-21 months, rebleeding was observed in one case. The stenoses of intrahepatic shunts and inferior vena vein respectively occurred in two cases requiring repeat intervention. Therefore, expandable venous stent is safe and effective in patients with BCS, and will be of great value in wide application and further study.
