ABSTRACT

PURPOSE

We aimed to investigate the feasibility and effectiveness of accessory hepatic vein recanalization (balloon dilatation/stent insertion) for patients with Budd-Chiari syndrome (BCS) due to long-segment obstruction of the hepatic vein.

METHODS

From March 2010 to December 2013, 20 consecutive patients with BCS, due to long-segment obstruction of three hepatic veins, treated with accessory hepatic vein recanalization (11 males, 9 females; mean age, 33.4±10.9 years; range, 22–56 years) were included in this retrospective study. Data on technical success, clinical success, and follow-up were collected and analyzed.

RESULTS

Technical and clinical success was achieved in all patients. Each patient was managed with a single accessory hepatic vein recanalization procedure. No procedure-related complications occurred. The diameter of the accessory hepatic vein was 8.45±1.47 mm (6–11 mm) at the stem, and there were many collateral circulations between the hepatic vein and the accessory hepatic vein. The mean pressure of accessory hepatic vein decreased from 47.50±5.59 cm H2O before treatment to 28.80±3.47 cm H2O after treatment (P < 0.001). Abnormal levels of total bilirubin, albumin, aspartate aminotransferase, and alanine transaminase improved after the treatment. During the follow-up, three patients experienced restenosis or stenting of the accessory hepatic vein.

CONCLUSIONS

In BCS due to long-segment obstruction of the hepatic veins, it is important to confirm whether there is a compensatory accessory hepatic vein. For patients with a compensatory but obstructed accessory hepatic vein, recanalization is a simple, safe, and effective treatment option.
