Abstract:
Objective To investigate the mid-term efficacy of retrievable stent filter placement for the treatment of Budd-Chiari syndrome (BCS) complicated with inferior vena cava (IVC) thrombosis. Methods Eight patients of BCS complicated with IVC thrombosis were enrolled in this study. IVC thrombosis included segmental occlusion (n = 2) and membranous occlusion (n = 6). In all patients, the IVC was re-canalized by using blunt wire after anticoagulation and thrombolytic therapy, then, the re-canalized site was expanded with small balloon, which was followed by the placement of retrievable stent filter, and, finally, IVC size was dilated with larger balloon. Anticoagulation and thrombolytic therapy was given after the procedure. And all the retrievable stent filters were withdrawn from the IVC through internal jugular vein when the thrombus in IVC was dissolved. In patients with segmental occlusion of IVC, in addition to the placement of retrievable stent filter a "Z" type vessel stent was also placed during the same interventional session. Follow-up examination with color Doppler sonography was conducted in all patients. Results Technical success was achieved in all 8 patients without pulmonary infarction or other complications both during and after the operation. Immediately after the thrombus completely disappeared, the retrievable stent filter was successfully taken out in all patients. During a following-up period of 3-12 months, color Doppler sonographs showed that the IVC remained patent in 6 patients and had a recurrence of stenosis in 2 patients. Conclusion Placement of retrievable stent filter is a safe and effective treatment for BCS complicated with IVC thrombosis.
