摘要
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 evaluate the diagnostic value of prenatalechocardiography for fetal transition of great arteries. Methods： Theechocardiography features of six fetuses with transposition of great arteries were analyzed retrospectively using cardiac three - section analysis method. Four - chamber view, left and right outlet tract view, short - axis view, longitudinal view of aortic arch and ductus arteriosus, three vessel view and three vessel and trachea view （3V ＋ T） were displayed using two dimensional ultrasound. Based on the above sections, Aorta and pulmonary artery were traced by slightly modifying the position or direction of the transducer. Results： Six cases with transposition of great artery were detected since 2002, among which four cases were confirmed by autopsy, one women refused autopsy and one case was confirmed by neonatal echocardiography and surgery after birth. Conclusion： The short - axis view and left and right outlet tract view were the most important view to diagnose the transposition of great artery. Fourchamber view, longitudinal view of aortic arch and ductus arteriosus, three vessel view and three vessels and trachea view play an important role in detecting the companied fetal cardiac abnormalities.
