经皮球囊肺动脉瓣成形术的临床研究

Percutaneous balloon pulmonary valvuloplasty:clinical report of 45

目的 总结我院经皮球囊肺动脉瓣成形术的结果和经验。方法 采用经皮球囊瓣膜成形术治疗 4 5例先天性肺动脉瓣狭窄患者。结果 术前肺动脉跨瓣压力阶差 (△ P) 5 1.3± 2 4 .2 mm Hg,球 /瓣比为 1.3 5± 0 .17( 1.12～ 1.75 )。术后即刻效果良好 ,95 .6%的病例△ P<2 5 mm Hg。经 2～ 3 0月随访无再狭窄 ,未发生明显并发症。结论 经皮球囊肺动脉瓣成形术为简便、有效、安全。

Objective To summary the therapeutic results of percutaneous balloon pulmonary valvuloplasty(PBPV)performed in this hospital and gain relevant experiences.Methods 45 cases of congenital pulmonary valve stenosis(PS)were treated with percutaneous balloon pulmonary valvuloplasty.Results The preoperative pressure gradient △P between right ventricle and pulmonary was 51.3±24.2mmHg,and the ratio of balloon/valve ring was 1.35±0.17.The immediate postoperative effect was excellent with △P<25mmHg in 95.6% of the cases.No restenosis or other complications were observed during 2～30 months of follow up examination.Conclusion PBPV is a kind of safe,effective,easy to operate and economic therapeutics instead of surgery for PS.
