Combined thrombus aspiration and recanalization in treating Budd-Chiari syndrome with inferior vena cava thrombosis.

PURPOSE

To investigate the feasibility, safety, and effectiveness of combined thrombus aspiration and inferior vena cava (IVC) recanalization for Budd-Chiari syndrome (BCS) patients with IVC thrombosis.

MATERIALS AND METHODS

From March 2011 to October 2014, 17 consecutive BCS patients with IVC thrombosis [male 13, female 4 (mean age 52.6 ± 8.4 years, range 43-72 years)] treated by combined thrombus aspiration and IVC recanalization were enrolled in this retrospective study. An 8F guiding catheter was used as the aspiration catheter. During the treatment, the aspiration catheter was placed from the right femoral vein to the IVC thrombi, and a 20-ml syringe was connected with the aspiration catheter for thrombus aspiration. IVC recanalization was performed after thrombus aspiration. Data on technical success, clinical success, and follow-up were analyzed.

RESULTS

Technical success was achieved in all patients. After thrombus aspiration, 12 patients had no visible thrombi on IVC venography, while 5 patients were shown to have the IVC mural thrombi. Afterwards, 13 patients were treated by IVC balloon dilation, and 4 patients were treated by IVC stent insertion. No patient experienced dyspnea after treatment. The average IVC pressure decreased from 29.8 ± 3.4 cmH2O to 8.6 ± 2.1 cmH2O (P < 0.001). Clinical success was achieved in all patients. The average follow-up period was 15.3 ± 11.6 months (range 2-44 months). Long-term IVC patency was achieved in 15 of 17 patients.

CONCLUSION

Combined thrombus aspiration and IVC recanalization can be a safe and effective method for BCS patients with IVC thrombosis.
