【摘要】 对４７例先天性心脏病并肺动脉高压症患者作术中肺活检，并对肺切片中单位面积小动脉数量与术后早期结果作比较：发现肺动脉高压症患者单位面积肺小动脉数量明显下降，并且与ＨｅａｔｈＥｄｗａｒｄｓ肺血管病理定性分级的轻、重程度有关；单位面积肺小动脉数量小于０．３ｍｍ－２的病例，术后早期死亡比例（１２／２２，５４．５％），明显高于肺小动脉数大于０．３ｍｍ－２组（４／２５，１６．０％）。初步提示单位面积肺小动脉数量是反映肺动脉高压肺小动脉病变程度的定量指标，可作为估计临床手术预后的参考指标。更多还原

【Abstract】 Open lung biopsis was carried in 47 cases of congenital heart defect with pulmonary hypertension, the amount of pulmonary arteriole were calculated, and compared with the early result of operation and Heath Edwards classification in pathology. It was found that the amount of pulmonary arteriole was decreased in cases with pulmonary hypertension and the mortality in cases in which the amount of pulmonary arteriole are less than 0.3 mm -2 is much higher than that in cases in which the amount of pulmonary arteriole was more than 0.3 mm -2 . It indicated that the amount of pulmonary arteriole might be a useful predictive criterion for detection and prognosis of corrective operation in congenital heart defect with pulmonary vascular disease.更多还原
