摘要
对行经皮球囊肺动脉瓣成形术31例中28例进行随访,结果是近、中期随访的疗效稳定,未发现瓣膜再狭窄现象;虽然部分患儿在术后发生轻至中度 PI,但无继续加重,亦不影响心功能,提示本手术是一种安全有效的新疗法。
31 patients aged 2(1/2) to 13 yes underwent peutaneous balloon pulmonary val- vuloplasty(PBPV)since Jan.1986 to De.1988.28 cases(90.3%)were followed up for a pericd of 3 months to 3 ys.10 cases with single belloon technique,the ΔP fell from 3,6-16.6 kPa(7.90±4.53)to 0-3.1 kPa(1.44±0.76)(P<0.001).The eduction of ΔP was 77.4% (range,48-100%).18 eases with doule balloon tehniq'e,the ΔP fell from 4.2-14.9 kPa to 0-4.8 kPa(7.74±2.89 to 1.58±1.36)(P<0.001).The reduction of ΔP was 78.56%(range 25- 100%).EKG showed improvement of RVH in 5 cases.11 cases had mild to mederate pulmon- ary insufficiency.The results suggest that the dilation effect of PBPV is lasting,may be a preferable therapeutic procedure for management of moderate to severe valvular pulmonic ste- nosis.
