Objective
To determine the long-term patency and survival of percutaneous recanalization for hepatic vein (HV)-type Budd-Chiari syndrome (BCS).
Methods
From March 2009 to November 2014, consecutive symptomatic HV-type BCS patients were treated by percutaneous recanalization in our centers. These patients underwent main HV (MHV) or accessory HV (AHV) recanalization. Data on patient characteristics, technical success, clinical success, long-term patency, and survival were collected and analyzed.
Results
During the enrolled periods, a total of 143 symptomatic HV-type BCS patients were treated by percutaneous recanalization in our centers. Technical success was achieved in 140 of 143 patients. One hundred eleven patients underwent MHV recanalization, and 29 underwent AHV recanalization. Clinical success was achieved in 136 of 140 patients. The mean MHV/AHV pressure decreased from 33.5 ± 4.1 mmHg before treatment to 12.5 ± 3.1 mmHg after treatment (p = 0.000). The 136 patients were followed for 7–75 months (mean 33.9 ± 15.3 months). Twenty-eight patients experienced re-obstruction of MHV (n = 24) or AHV (n = 4) at 3 to 36 months (mean 18.0 ± 11.5 months) after treatment. The cumulative 1-, 3-, and 6-year primary patency rates were 91.1, 77.4, and 74.0 %, respectively. The cumulative 1-, 3-, and 6-year secondary patency rates were 97.0, 92.4, and 88.8 %, respectively. The cumulative 1-, 3-, and 6-year survival rates were 97.7, 92.2, and 90.0 %, respectively.
Conclusion
Percutaneous recanalization can provide good long-term patency and survival in HV-type BCS patients.
