目的:评估经皮球囊成形术(PBPV)治疗先天性肺动脉瓣狭窄(PS)的临床疗效。方法:全组43例,经临床、心电图、X线及超声心动图证实为单纯PS,扩张前先确定PS的类型和测量瓣环大小,球囊直径选择比瓣环径线大20%～40%,扩张后即刻测肺动脉跨瓣压差,观察比较PBPV后肺动脉瓣开放、射流及肺动脉瓣、三尖瓣反流情况。结果:43例患者均采用单球囊,全部扩张成功,除2例并发肺动脉瓣轻度关闭不全外,无任何严重并发症发生,肺动脉跨瓣压差扩张后下降62.68%(P<0.01)。结论:PBPV是一种治疗PS安全、有效的介入治疗方法,操作简单,无严重并发症,缩短了住院时间,已成为治疗PS的首选方法。
Objective: To evaluate the clinical efficacy of percutaneous balloon angioplasty (PBPV) in the treatment of congenital pulmonary stenosis (PS). Methods: The whole group of 43 patients were confirmed as simple PS by clinical, electrocardiogram, X-ray and echocardiography. Before the expansion, the type of PS and the size of the annulus were determined. The diameter of the balloon was 20% -40 %, Measured immediately after the expansion of pulmonary valve transvalvular pressure, observed after PBPV pulmonary valve open, jet and pulmonary valve, tricuspid regurgitation. Results: All the 43 patients underwent balloon dilatation. All cases were successfully expanded. Except for 2 cases with mild pulmonary insufficiency, there was no serious complication. The pulmonary valve transarticular pressure decreased by 62.68% (P <0.01). Conclusion: PBPV is a safe and effective interventional therapy for PS. It has simple operation, no serious complication, shortened hospitalization time and has become the preferred method for the treatment of PS.
