胎儿畸形的产前超声诊断现状

产前超声检查是诊断胎儿畸形最常用而有效的检测手段,产科超声检查分层次,分时段。常规产科超声的应用对筛查胎儿畸形起重要作用,阴道超声应用使得某些胎儿畸形的发现时间提前,孕中期行胎儿系统超声的检查可检出大部分胎儿畸形,孕晚期超声检查为胎儿畸形的补漏检查,多普勒超声、三维超声与二维超声的联合应用可明显提高胎儿畸形的检出率。

Research Status of Prenatal Ultrasonic Diagnosis in Fetal Malformation

Prenatal ultrasonic examination is most commonly used and effective means of detection in fetal malformations,and obstetric ultrasonic examination is used in different periods and different levels.Applications in routine obstetric ultrasound play an important role in screening for fetal malformations.Application of transvaginal ultrasound findings make some time ahead of fetal malformation.Most fetal abnormalities can be detected by systematic fetal ultrasonic examination in second trimester.Missing of fetal malformation can be detected by ultrasonic examination in the third trimester.Doppler ultrasound,three-dimensional ultrasound in combination with two-dimensional ultrasound can improve the detection rate of fetal malformations.
