经皮球囊肺动脉瓣膜成形术治疗小儿肺动脉瓣狭窄

Percutaneous balloon valvulopasty of congenital pulmonary valve stenosis in children

目的 :探讨经皮球囊肺动脉瓣膜成形术 (PBPV)治疗小儿先天性肺动脉瓣狭窄的临床效果。方法 :7例单纯先天性肺动脉瓣狭窄 (PS) ,根据患儿的年龄和 PS的轻重 ,3例选择单球囊法 ,4例采用双叶球囊法 ,进行瓣膜扩张术。结果 :7例患儿 PBPV术后 ,即时跨瓣压力阶差 (Δ P)均显著下降 (ΔP<2 0 mm Hg)。结论 :PBPV是简便、安全。

Objective:To explore the clinical effect of percutaneous balloon pulmonary valvuloplasty (PBPV) for the treatment of congenital pulmanary valvular stenosis (PS) in children. Methods:From March 1996 to December 1998,PBPV on seven children with PS using one balloon or dual balloon were performed according to age and degree of PS.Results:There were remarkable declines in postballooning residual transvalvular gradient (ΔP) immediately after operation on seven children(ΔP<20mmHg).Conclusion: The first choice for treating patients with PS should be PBPV,which is simple and safe in operation,effective in therapy and cheap in price.
