本文报告应用国产球囊导管行经皮扩张成形术治疗小儿先天性肺动脉辦狭窄(PS)30例,其中男11例,女19例;年龄1 1/2～13岁,平均5.6岁,<3岁9例,体重7～31kg,平均15.2kg。术前右室收缩压与肺总动脉收缩压差(ΔP)为14.2±6.18kPa(105.9±46.35mmHg),扩张后降至2.84±1.96kPa(21.3±14.7mmHg),ΔP下降80%左右。其中2例因球囊导管未能到位而改行手术治疗。本文就PBPV从病例选择、技术操作、术中监测等进行了讨论。作者认为国产球囊导管价廉,且完全达到临床应用要求。
This article reports the application of domestic balloon catheter percutaneous dilation in the treatment of pediatric congenital pulmonary artery stenosis (PS) 30 cases, including 11 males and 19 females; aged 1 1/2 to 13 years, mean 5.6 years, <3 years old 9 cases, weighing 7 ~ 31kg, an average of 15.2kg. Preoperative right ventricular systolic pressure and pulmonary artery systolic pressure difference (ΔP) was 14.2 ± 6.18kPa (105.9 ± 46.35mmHg), expanded to 2.84 ± 1.96kPa (21.3 ± 14.7mmHg), ΔP decreased by 80%. Two of them were surgically treated for balloon catheter failure. In this paper, PBPV from the case selection, technical operation, intraoperative monitoring were discussed. The author believes that domestic balloon catheter is cheap and fully meet the clinical application requirements.
