Recanalization of accessory hepatic vein for hepatic vein-type Budd-Chiari syndrome.
OBJECTIVE
To evaluate the clinical efficacy and long-term outcomes associated with the treatment of hepatic vein (HV)-type Budd-Chiari syndrome (BCS) via accessory HV (AHV) recanalization.


METHODS
In total, 26 HV-type BCS patients underwent AHV recanalization between July 2014 and December 2019 at our hospital, while 73 HV-type BCS patients without compensatory AHV underwent main HV (MHV) recanalization and served as controls in the present study. Short- and long-term clinical outcomes were compared.


RESULTS
AHV and MHV recanalization approaches were both associated with 100% technical success rates, with one recanalization procedure being performed per patient. Respective clinical success rates for the AHV and MHV recanalization approaches were 96.2% and 94.5% (P = 0.744). Re-obstruction rates were comparable between these two approaches at 20% and 34.8%, respectively (P = 0.17). Primary cumulative 1-, 2-, and 5-year patency rates in the AHV group were 96.0%, 91.6%, and 76.3%, respectively, whereas in the MHV group, these three respective rates were 87.0%, 78.6%, and 58.6% (P = 0.048). Secondary cumulative 1-, 2-, and 5-year patency rates in the AHV group were 96.0%, 96.0%, and 96.0%, respectively, whereas in the MHV group, they were 97.1%, 97.1%, and 81.8%, respectively (P = 0.289). Cumulative 1-, 2-, and 5-year survival rates for AHV group patients were 96.0%, 96.0%, and 96.0%, respectively, while for the MHV group, these respective rates were 98.6%, 95.2%, and 89.7% (P = 0.462).


CONCLUSION
HV-type BCS can be safely and effectively treated via AHV recanalization, which may achieve longer patency relative to MHV recanalization.
