Interventional or semi-interventional treatment for Budd-Chiari syndrome.

Objective: Report the results of interventional or semi-interventional techniques for 173 patients with Budd-Chiari syndrome.

Method: This group included 120 males and 53 females. The pathologic lesions composed of localized complete occlusion of inferior vena cava (IVC) (78), IVC stenosis (49), IVC membrane with a hole (37), membrane of hepatic vein (HV) (3), IVC thrombosis (4), IVC membrane with thrombosis (2) and IVC lesion with occlusion of HV (32). Treatment methods included that I: Percutaneous transinferior vena cava angioplasty (PTA) (76); II: IVC PTA with stent (59); III: Percutaneous transhepatic vein recanalization (3); IV: IVC thrombolysis through a catheter (4), V: Combined transcardiac and transfemoral venous membranotomy and balloon dilation (22); VI: V and stent (17); VII: Stenting during radical surgery (3); VIII: Additional operation after intervention (23).

Results: The immediate technique success rate for intervention was 90.1%, for the semi-intervention was 100%. The IVC pressure was reduced from 3 to 29 cmH2O. Complications occurred in 8 cases. The death rate was 2.9%. A follow-up study showed the recurrence rates were 14.5% in IVC PTA group, 1.7% in IVC PTA with stent, 18.2% in combined technique without stent and no recurrence was found in other groups.

Conclusion: The PTA is the first choice for localized lesions. When elastic recoil occurs, immediate stenting is suggested. The semi-interventional approach is advised for PTA failure and more complicated cases. For those with both IVC lesion and occlusion of HV, the additional operation is needed after IVC intervention.
