PTA and stenting for various types of Budd-Chiari syndrome

Objective: To investigate and evaluate PTA and stenting for various types of Budd-Chiari syndrome (BCS). Methods: 89 patients with BCS were diagnosed and treated during 7 years. The interventional procedures included: Percutaneous balloon dilatation (PBD) of inferior vena cava (IVC), PBD and stent placement for IVC, hepatic vein angioplasty via trans jugular vein, hepatic vein angioplasty via transhepatic and trans jugular approach, accessory hepatic vein angioplasty, percutaneous dual balloon dilatation for IVC and hepatic vein, and percutanous dual stent placement for IVC and hepatic vein. Results: The achievement ratio of PTA and stent placement was 96% and the mortality was 0%. The serious complication of PTA and stent placement of BCS was penetration into the pericardium, endovascular stent migration into right atrium. Conclusion: 1. PTA is a reliable procedures in treating type I a, II and III BCS, and TIPPS is useful for type I b BCS. But PTA and stenting is necessary for patients with type IV BCS. 2. Thrombolysis is needed for patients with type III, IV BCS. 3. Guiding of Color Doppler Ultrasound can improve the success of percutanous hepatic vein and reduce complications. (authors)
