产前四维超声在胎儿畸形诊断中的应用价值

Application Value of Prenatal Four-Dimensional Ultrasound in the Diagnosis of Fetal Malformations

目的探讨产前四维超声在胎儿畸形诊断中的应用价值。方法纳入910例在接受产前检查的孕妇作为研究对象。比较二维超声与四维超声对颜面部、中枢神经系统、消化系统、心脏系统、泌尿系统、四肢骨骼系统、皮肤、胸腹腔畸形的检出结果,以随访结果为标准,比较两者诊断胎儿畸形的准确率。结果910例孕妇中,单胎902例,双胎8例。共检出畸形胎儿58例,其中48例终止妊娠,10例继续妊娠。经随访证实畸形处数64处,二维超声检出胎儿畸形39处,检出率为60.94%,四维超声检出胎儿畸形55处,检出率为85.94%,四维超声检出率显著高于二维超声(P<0.05)。结论与二维超声相比,产前四维超声可提高胎儿畸形的筛选效率与准确度,值得临床推广。

Objective To explore the application value of prenatal four-dimensional ultrasound in the diagnosis of fetal malformations.Methods A total of 910 pregnant women who underwent antenatal check-ups in our hospital were included as research subjects.Compare the detection results of facial,central nervous system,digestive system,cardiac system,urinary system,limb skeletal system,skin,chest and abdominal cavity deformities by two-dimensional ultrasound and four-dimensional ultrasound.With the follow-up results as the standard,the accuracy of the two groups in diagnosing fetal abnormalities was compared.Results Among 910 pregnant women,902 had single pregnancy and 8 had twin pregnancy.A total of 58 malformed fetuses were detected,of which 48 had terminated their pregnancy,and 10 continued their pregnancy.The follow-up confirmed 64 malformations,39 fetal malformations were detected by two-dimensional ultrasound,the detection rate was 60.94%,and 55 fetal malformations were detected by four-dimensional ultrasound,the detection rate was 85.94%,and the detection rate of four-dimensional ultrasound was significantly higher than that Two-dimensional ultrasound(P<0.05).Conclusion Compared with two-dimensional ultrasound,prenatal four-dimensional ultrasound can improve the efficiency and accuracy of screening for fetal malformations and is worthy of clinical promotion.
