    Abstract:
    PURPOSE: To determine the clinical effectiveness and long-term outcomes of endovascular treatment for hepatic vein (HV)-type Budd-Chiari syndrome (BCS). MATERIALS AND METHODS: From June 2011 to August 2016, 68 consecutive patients with symptomatic HV-type BCS underwent endovascular treatment in our center. Data on the baseline characteristics, technical success, clinical success, and long-term outcomes were collected and analyzed retrospectively. RESULTS: The technical success rate of endovascular treatment was 100%. Fifty patients underwent HV recanalization, and 18 underwent accessory HV (AHV) recanalization. The clinical success rate was 95.6% (65/68). During a mean follow-up period of 29.4 ± 13.6 months, 19 patients experienced re-obstruction of either the HV (n = 18) or the AHV (n = 1). The cumulative 1-, 2-, and 5-year primary patency rates were 80.0, 72.8, and 67.9%, respectively. The cumulative 1-, 2-, and 5-year secondary patency rates were 93.8, 90.3, and 82.9%, respectively. Univariate and multivariate analyses revealed that the independent predictor of a prolonged primary patency duration was recanalization of the AHV. Five patients died 1-28 months (median, 15 months) after treatment. The cumulative 1-, 2-, and 5-year survival rates were 96.9, 93.4, and 91.2%, respectively. There was no significant difference in survival between the HV and AHV recanalization groups. CONCLUSION: Endovascular treatment is effective for patients with HV-type BCS. It can result in excellent long-term patency and survival rates. If it is applicable, AHV recanalization should be considered prior to treatment in order to achieve a longer patency.
