摘　　要：用彩色多普勒超声心动围观察了３０例正常人和经右心导管测压的２８例先天性心脏病人的肝静脉血流（ＨＶＦ）频谱。结果显示肺动脉高压（ＰＨ）病人ＨＶＦ频谱测值具有特征性变化，其中衍生比值（ａＶｍ＋ｖＶｍ）／（ｓＶｍ＋ｄＶｍ）及（ａＶＩ＋ｖＶＩ）／（ｓＶＩ＋ｄＶＩ）与肺动脉平均压（ＰＡＭＰ）相关最好（分别为ｒ＝０．７０５７，ｒ＝０．６５０９，Ｐ＜０．０１），以该比值作为判断ＰＨ的标准，可获得较高的敏感性和特异性。ＨＶＦ频谱改变评估ＰＨ可以弥补其它方法之不足或结合其它方法提高估测肺动脉压的准确性。For seeking a new approach to evaluate pulmonary hypertension (PH) by the changes ofhepatic vein flow (HVF) spectrum, we examined HVF velocity wave-form in 30 nomal subjects and 28patients of congenital heart disease undergoing diagnostic right cardiac catheterization by color Dopplerechocardiography and found the characteristic changes in HVF spectrum of patients with PH. The bestcorrelation was acquired between (aVm + vVm ) / (sVm + dVm ) or (aVI + vVI ) / (sVI + dVI ) and meanpulmonary artery pressure (r=0. 7057,r= 0. 6509,P<0. 01 respectively). Evaluating PH with (aVm+vVm)/(sVm+dVm) or (aVI+vVI)/(sVI+dVI) resulted in better sensitivity and specificity. We concluded that the changes of HVF spectrum is a new useful method in evaluating PH and could counteractthe weakness of the other ways or assess the pulmonary artery pressure well as combined with the others
