摘要
目的观察大球囊扩张血管成形术治疗下腔静脉节段阻塞型Budd-Chiari syndrome(SOVC,Segmental obstruction of the IVC)前后血流动学变化,探讨其安全性,疗效和并发症。方法SOVC患者38例,在DSA监视下,先用小球囊预扩张,后以直径25mm～30mm大球囊治疗性扩张下腔静脉。结果26例患者成功血管成形治疗,病变血管内径,术前2.77±2.32mm,术后即刻16.88±2.99mm,一月后10.61±2.45mm;病变远心段IVC压力:术前33.73±8.24cmH2O,术后12.77±2.79cmH2O;侧枝循环显影基本消失。随访6月～6年4个月,复发率19.23%。结论大球囊扩张血管成形术治疗SOVC,安全,有效,术后近期病变血管回缩是影响其远期疗效主要因素之一。
Objective To observe the hemdynamic change of patients with segmental obstruction of the inferior vena cava by dilation with bigger balloon and study its safety,clinical therapeatic effects and complications.Methods：Thirty-eight patients with segmental obstruction of the inferior vena cava were treated by interventional therapy.The diameter of the balloon catheters were 25-30mm.Results：Twenty-eight patients were dilated successfully.The inside vascular diameter was 2.77±2.32mm in the pre-operation,16.88±3.99mm post-operation and 10.61±2.45mm after 4 weeks.The pressure of IVC was 33.73±8.24cmH2O in the pre-operation and 12.77±2.79cmH2O in the post-operation.Collateral circulation of arm disappeared mostly or decreased markedly after operation.Follow-up 6 months～6.3 years,recrudescence rate was 19.23%.Conclusion It is safe,efficient,rare side-effect and low recurrent to treat SOVC with bigger balloon,and shrinkage after dilation with bigger balloon.
