【摘要】 目的评价四腔心和左右流出道切面在胎儿先天性心脏畸形(congenital heart defect,CHD)广泛性筛查中的价值。方法采用彩色多普勒超声诊断仪,在显示四腔心切面的基础上,据胎儿体位不同,选择矢状、冠状或横切显示左、右室流出道。根据CHD病理特征,把胎儿CHD分为单纯型CHD和复杂型CHD。结果四腔心切面在产前诊断复杂型CHD和单纯型CHD中的敏感度分别为52.4%和28.6%;四腔心和流出道切面联合应用在产前诊断复杂型CHD和单纯型CHD中的敏感度分别为90.5%和42.9%。结论四腔心和流出道切面联合应用是提高产前胎儿CHD诊断率的重要方法。更多还原

【Abstract】 Objective To investigate the value of the four-chamber and out flow tract plane in prenatal screening for congenital heart defects(CHD).Methods Four-chamber and out flow tract plane were used to detect fetal hearts.The out flow tract plane demonstrated transverse,sagittal or coronal orientation according to the fetal position.Fetal CHD was classified into simple and complex forms pathologically.Results The sensitivity of unitary four-chamber plane and combined with out flow tract plane in screening complex form CHD were 52.4%(11/21) vs 90.5 %(19/21).The sensitivity of unitary four-chamber plane and combined with out flow tract plane in screening simple form CHD were 28.6 %(2/7)vs 42.9%(3/7).Conclusion Combination of four-chamber and out flow tract plane is necessary in prenatal screening of complex CHD.更多还原
