经皮球囊肺动脉瓣膜成形术治疗小儿肺动脉瓣狭窄

<title>rcutaneous 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 1996年3月-1998年12月,7例患儿确诊为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(△P)均显著下降(△P<20mmHg)。结论 PBPV是简便、安全、经济的治疗PS的首选方法。

<abstract>jective 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, we performed PBPV on seven children with PS using one balloon or dual balloon according to age and degree of PS. Results There were remarkable declines in postballooning residual transvalvular gradient (△P) immediately after operation on seven children(△P<20mmHg). Conclusion The first choice for treating patients with PS should be PBPV which is simple and safe in operation, effective in theroapy and cheap in price.
