摘　　要：目的评估经皮球囊肺动脉瓣成形术(PBPV)治疗先天性肺动脉瓣狭窄(PS)的临床疗效。方法总结近11年经临床、心电图、X线及超声心动图证实为单纯PS 48例。行瓣膜扩张术前先确定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与右心室跨瓣压差(△P),观察比较PBPV后肺动脉瓣开放、射流及肺动脉瓣、右房室瓣反流情况。结果 48例患者中38例采用单球囊,10例双球囊扩张,均扩张成功,无任何严重并发症发生。结论 PBPV是治疗单纯PS安全、有效的介入治疗方法,无严重并发症,已成为治疗PS的首选方法。Objective To evaluate the clinical efficacy of percutaneous balloon pulmonary valvuloplasty （PBPV） in treating simple pulmonary stenosis （PS）. Methods A total of 48 patients with simple PS, who were encountered in authors＇ hospital during the past 11 years, were enrolled in this study. The diagnosis was confirmed by clinical manifestations, ECG, X-ray and echocardiography. The type of PS and size of valvular ring were determined before the dilatation of valvular ring was carried out. The balloon with the diameter being （20 - 40）% bigger than the valve orifice diameter was employed. Immediately after the dilatation of valvular ring, the PA-RV（pulmonary artery and right ventricle） pressure difference across the pulmonary valve was determined. After PBPV the opening of pulmonary valve, the jet of blood flow and the regurgitation of pulmonary as well as tricuspid valves were checked. Results Of the 48 patients, single- balloon was used in 38 and double-balloon was employed in 10. The dilatation procedure was successfully accomplished in all patients. No severe complications occurred. Conclusion For the treatment of simple pulmonary stenosis, percutaneous balloon pulmonary valvuloplasty is a safe and effective method with no severe complications. Therefore, percutaneous balloon pulmonary valvuloplasty should be regarded as the therapy of first choice for simple pulmonary stenosis.（J Intervent Radiol, 2013, 22： 054-056）
