经皮球囊肺动脉瓣成形术临床应用

CLINICAL APPLICATION OF PERCUTANEOUS BALLOON PULMONARY VALVULOPLASTY

作者1988年～1998年对62名先天性肺动脉瓣狭窄患者实施了经皮球囊肺动脉瓣成形术(PBPV),患者平均年龄201岁。PBPV后即刻肺动脉瓣跨瓣压差(ΔP)由术前71±27mmHg降至37±15mmHg,54例随访1～9年,平均47±21年,ΔP进一步降为24±9mmHg。术中及术后无严重并发症。结论:PBPV治疗肺动脉瓣狭窄安全、有效,即刻与中远期效果均良好。

To study the immediate and intermediate-late result of percutaneous balloon pulmonary valvuloplasty (PBPV) for congenital pulmonary valve stenosis.Methods:62 patients with congenital pulmonary valve stenosis were performed PBPV from 1988 to 1998 in our department, the relative clinical data was collected and analyzed.Results:The systolic gradient (△P) from right ventricular to pulmonary artery was reduced from 71±27 mmHg to 37±15 mmHg immediately after PBPV. 54 patients received follow-up survey (mean 4.7±2.1 years), their △P was reduced progressively to 24±9 mmHg. Conclusions: Balloon pulmonary valvuloplasty is a safe and effective method for treating the patients with pulmonary valve stenosis, the late results of this treatment are as good as early results.
