Comparative study of predilation with stent filter for Budd-Chiari syndrome with old IVC XXXX : a nonrandomized prospective trial.

@entity1 @entity715 @entity1151
PURPOSE: To evaluate whether predilation approach yield intermediate-term results were better than those with stent filter approach. MATERIALS AND METHODS: 59 BCS @entity1 with old IVC @entity715 were selected for the treatment with a stent filter (n = 33, group A) or predilation (n = 26, group B) before thrombolysis, and subsequently underwent color Doppler ultrasound follow-up at our hospital. Data relating to the technical success, color Doppler ultrasound results, cost, mortality, morbidity, and final clinical results were collected prospectively and follow-ups were performed 1, 3, 6, and 12 months after the procedures, and annually thereafter. RESULTS: Sent filter placement, thrombolysis and predilation were technically successful in all @entity1 , with no procedure-related complications. Stent migration upward occurred in two @entity1 , and removal of the stent filter was technically successful in 32 of 33 @entity1 in group A. Inferior vena cavagrams performed before dilation with a 30-mm balloon catheter demonstrated that the IVC @entity715 had completely resolved in all @entity1 without @entity1151 . Reobstruction of the IVC without @entity715 was observed in three @entity1 . Short of higher overall complications and costs in group A when compared to group B, there were no other differences in the clinical and color Doppler ultrasound findings, and primary patency rate between the two groups. All @entity1 are alive with no recurrence of @entity715 at the time of this report. CONCLUSIONS: BCS @entity1 with old IVC @entity715 treatment with predilation approach yielded intermediate-term results that were better than those with the stent filter approach.
