儿童先天性心脏病肺动脉高压的胸片研究

本文收集１２０例儿童先天性心脏病患者胸部平片及右心导管检查肺动脉收缩压测量结果，研究胸片肺动脉测量指标与肺脉压的相关性，结果表明：胸片指标与肺动脉压间存在良好的相关关系；胸片指标判断有无肺动脉高压的准确性达７６．７％，判断中，重度肺动脉高压的准确性达８４．８５；建立了预计肺动脉压的回归方程，肺动脉压的回归预计值与实测值相比，６２．５％病例相差≤１．３ｋＰａ９４．２％病例相差≤２．７ｋＰａ。本文并按

Roentgenologic Study of Pulmonary Artery Hypertension in Congenital Heart Disease of Children

cases of congenital heart disease of children were reviewed to study the statistical correlation of measurements of pulmonary artery on plain chest radiograph with systolic pulmonary arierial pressure(PAP)measured by right cardiac catheterization and tried to estimate PAP from chest film.The result showed that there was a good correlation between PAP and radiolgic indices.Pulmonary hypertension could be predicted from chest radiograph with 76.7% accuracy,the moderate and severe pulmonary hypertension could be predicted more accurately.The difference between regressive estimated value and catheter value of PAP was 1.3kPa in 62.5% cases,adn 2.7kPa in 94.2% cases.The patients of ASD,VSD and PDA were further discussed respectively.
