经皮穿刺球囊扩张成形术治疗肺动脉瓣狭窄

PERCUTANEOUS BALLOON PULMONARY VALVULOPLASTY(PBPV)

报告8例经皮穿刺球囊肺动脉瓣扩张成形术(PBPV)的结果。本组男性3例,女性5例,年龄5～26岁。7倒用单球囊、1例双球囊扩张。肺动脉瓣口直径由8.4±2.2扩张至16.4±1.5mm,右室收缩压由16.9±5.3下降至9.1±3.8kPa,右室-肺动脉压差由14.9±5.1降至6.6±3.9kPa;心排血指数由3.2±0.3增加至5.1±0.7L/min·m^(-2)(P均<0.001)。治疗后症状消失或基本消失,杂音明显减轻。术后4～5天出院。

This paper reported the results of balloon pulmonary valvuloplasty for 8 patients (single-balloon for 7 cases,double-balloon for 1 case).The meanpulmonary valve orifice in diameter (PVOD) was dilated from 8.4±2.2 preoperation to 16.4±1.5mm of postoperation,the systolic pressure in rightventricle (RV)was reduced from 16.9±5.3 to 9.1±3.8kPa,the pressure gradient from RV to pulmonary artery was reduced from 14.9±5.1 to 6.6±2.9 kPa,the cardiac index was increased from 3.2±0.3 to-5.1±0.7L/min m-2.The symptoms and heart murmur were nearly,subsided after treatment,the patients dischargd within 5 days after operation.PBPV is a nonoperative procedure with good efffect and.safety.
