目的探讨产前二维与三维超声,诊断罕见无心畸胎序列征的价值。方法回顾2014~2015年来在我院行产前超声检查的双胎或多胎孕妇,对胎儿行常规系统地产前超声检查,利用实时三维超声成像,尽量确定每个双胎或多胎的绒毛膜性。用GE voluson E8,GE voluson 730,SIMENS Premier彩超仪进行检查,将检查结果与分娩后或引产后死胎的尸检结果进行对比。结果经产前超声检查发现四例双胎无心畸胎序列征,3例引产后证实,1例为提前分娩后证实与产前超声检查结果一致。结论系统性的产前二维与三维超声检查能够更准确地诊断双胎无心畸胎序列征,提高诊断符合率,及时终止妊娠,有利于提高优生优育。
Objective To investigate the value of prenatal two-dimensional and three-dimensional sonography in the diagnosis of rare heartburn sequences. Methods A retrospective review of prenatal ultrasound examination of twin or multiple pregnant women in our hospital from 2014 to 2015 was performed on a routine prenatal ultrasound system using a real-time three-dimensional sonography to determine the chorionicity of each twin or multiple fetus. The test was performed on a GE voluson E8, a GE voluson 730, a SIMENS Premier color-doppler, and the results were compared with autopsy results of stillbirth after or after labor. Results Prenatal ultrasound examination found that four cases of twins without cardiac teratogenic sequence sign, 3 cases after induction of labor confirmed that 1 case of early delivery confirmed the same prenatal ultrasound results. Conclusions The systematic two-dimensional and three-dimensional prenatal examination of prenatal ultrasound can diagnose the sequence of fetal uninvolved twins more accurately, improve the accuracy of diagnosis and terminate the pregnancy in time, which is beneficial to improve prenatal and postnatal care.
