Percutaneous recanalization for combined-type Budd-Chiari syndrome: strategy and long-term outcome.

PURPOSE: To investigate the feasibility, strategy, and long-term outcome of percutaneous recanalization for combined-type Budd-Chiari syndrome (BCS).

METHODS: From December 2007 to August 2014, consecutive symptomatic combined-type BCS patients were treated by percutaneous recanalization in our centers. Inferior vena cava (IVC) recanalization was the first-stage treatment for all patients. Recanalization of one hepatic vein (HV) was the second-stage treatment for the selected patients. If the patient had the compensatory and patent accessory HV (AHV), we observed this patient for 7 days after IVC recanalization. If the symptoms of portal hypertension improved, HV recanalization was not needed. Otherwise, HV recanalization was performed. If the patient had no patent AHV, HV recanalization was performed 3 days after IVC recanalization. Data on technical success, clinical success, and follow-up were analyzed, respectively.

RESULTS: Sixty-two symptomatic combined-type BCS patients were enrolled. Technical success of percutaneous recanalization was achieved in 60 patients. Among them, 52 patients had the patent AHV and underwent single IVC recanalization, and 8 patients had no patent AHV and underwent combined IVC and HV recanalization. Clinical success was achieved in all of the 60 patients. Three patients died during the follow-up. The cumulative 1-, 2-, and 4-year survival rates were 98.3%, 96.5%, and 92.7%, respectively.

CONCLUSION: Percutaneous recanalization is suitable for most combined-type BCS patients. Treatment strategy can be made according to the situation of AHV. If the patient has the patent AHV, single IVC recanalization is enough. Otherwise, combined IVC and HV recanalization should be performed.
