目的:探讨产前超声心动图对胎儿大动脉转位的诊断价值。方法:回顾性分析自2002年以来6例经胎儿大动脉转位的产前超声心动图表现。采用心脏三节段分析法进行分析,用二维超声心动图显示四腔心、左室流出道、右室流出道、心底短轴、主动脉弓、动脉导管弓、三血管切面及三血管气管切面,在各标准切面基础上微调探头的方向以追踪大血管的走行及相互关系。结果:6例胎儿大动脉转位,4例尸体解剖检查(尸检)证实,1例引产后拒绝尸检,1例被产后超声心动图和手术证实。结论:心底短轴切面和左右心室流出道切面是诊断胎儿大动脉转位的主要切面,四腔心、三血管气管、三血管、主动脉弓长轴、两心房等切面对大动脉转位合并的畸形也具有重要的价值。
Objective: To investigate the value of prenatal echocardiography in the diagnosis of transposition of fetal aorta. Methods: A retrospective analysis of 6 prenatal echocardiographic manifestations of transsphenoidal artery transection since 2002 was performed. Three-dimensional analysis of the heart was used to analyze the two-dimensional echocardiography with four-chamber heart, left ventricular outflow tract, right ventricular outflow tract, cardiac arcuate axis, aortic arch, artery catheter arch, The standard section based on fine-tuning the direction of the probe to track the blood vessels walk and the relationship between. Results: Transposition of fetal arteries in 6 cases and autopsy in 4 cases (autopsy) confirmed that one case rejected postmortem examination and one case was confirmed by postpartum echocardiography and surgery. Conclusion: Myocardial short axis views and left ventricular outflow tract sections are the main sections for diagnosis of transposition of fetal aorta. Four anterior chamber, three-vessel trachea, three vessels, aortic arch long axis, Has important value.
