胎儿畸形的产前超声诊断（附50例病例分析）

ANTENATAL DIAGNOSIS OF FETAL DEFORMITY BY ULTRASONOGRAPHY(REPORT OF 50 CASES)

１９８４年１０月～１９９２年１２月，我院产科娩出的畸形儿５０例。对５０例畸形儿的产前超声检查、产后临床、病理及预后等情况进行了分析对照。５０例中孕２８周前Ｂ超确诊后引产１２例。结果显示，坚持孕中期，特别是孕２０～２４周行超声检查对降低围产儿死亡率十分重要，运用Ｂ超声显像技术对胎儿某些结构变化进行连续观察追踪，对提高胎儿畸形的诊断符合率有重要意义。

The antenatal sonograms,postpartum clinical and pathological examinations of50 cases of deformed fefus were analysed.12 cases among them with fetuses born in ourhospital form October 1984 to December 1992 were diagnosed by ultrasonography before28 weeks gestational age. So their pregnancies were terminated.Utrasonography inmidtrimester,especially in 20 to 24 weeks gestational age,is very important to reducingthe mortality of perinatal fetus. Continuous follow up observations tracing the fetus withabnormal structure by two dimensional ultrasonography can raise the conformity rate ofantenatal diagnose of fetal deformity.
