对比研究胎儿复杂心脏畸形的超声心动图特点与病理检查结果

目的 探讨应用超声心动图胎儿序列切面、系统扫查方法在诊断胎儿复杂先天性心脏畸形方面的临床应用价值。方法 借鉴美国超声心动图学会所提供的胎儿超声心动图检查的标准和规范性指南，对352例胎儿进行产前心脏超声心动图检查,并对因严重心脏畸形引产的胎儿产前超声心动图结果与胎儿病理解剖结果进行对比。结果 352例中产前胎儿超声心动图检出18例胎儿存在复杂心脏畸形，合计58处心脏畸形，均经引产病理解剖证实，解剖时还发现产前超声心动图漏诊心脏畸形5处（1处主动脉弓缩窄、2处永存左上腔静脉、2处右位主动脉弓）、诊断略有偏差心脏畸形3处（2处动脉发出略有偏差、1处主动脉与肺动脉间异常通道）, 胎儿超声心动图产前诊断心脏畸形的准确度为94.83% (55/58),敏感度为92.06%（58/63），对严重心脏畸形诊断的检出率可达100% (18/18)。结论 胎儿超声心动图序列切面系统检查方法，对多数严重胎儿心脏畸形可做出明确诊断，其对胎儿复杂心脏畸形的检出率与病理诊断结果无显著性差异，故其可作为诊断复杂胎儿心脏畸形的推荐方法。

Comparison of fetal echocardiographic characteristics and pathological findings about fetal cardiac complex malformation

Objective To investigate the clinical application of fetal echocardiography in the diagnosis of complex fetal cardiac malformation using the sequence section planes and system scanning the fetal body. Methods Using American Society of Echocardiography guidelines and standards for performance of the fetal echocardiogram,do antenatal examination for 352 cases to found if there are cardiac malformation in their fetuses,and 18 of 352 cases do induction of labor due to severe cardiac malformation,then the pathol...
