三维超声检查中孕期高危胎儿临床价值

目的:探讨三维超声检查中孕期高危胎儿的临床价值。方法:对高危胎儿分系统进行二维超声检查,再行三维超声成像,明确胎儿情况,与引产或出生后的随访结果对照分析。结果:1667例高危胎儿进行三维超声检查,检出各种结构异常78例,漏诊8例,胎儿结构异常发生率5.16%。78例中严重的胎儿结构异常32例,占41.03%,轻微的胎儿结构异常46例,占58.97%。胎盘异常15例,发生率0.89%;羊水异常119例,发生率7.14%。1667例高危胎儿二维超声检查符合率70.93%,三维超声检查符合率87.21%。结论:该方法能对高危胎儿的结构异常进行明确诊断,是减少漏诊及误诊、降低医疗风险的重要方法。

Clinical value of three-dimensional ultrasound in examination of high risk fetuses in second trimester

Objective:To explore the clinical value of three-dimensional ultrasound in examination of high risk fetuses in second trimester.Methods:All systems of the high risk fetuses were examined by two-dimensional ultrasound and three-dimensional imaging,then the results were compared to those after induced abortion or birth.Results:1 667 high risk fetuses underwent three-dimensional ultrasound,78 fetuses were diagnosed as structural abnormality,8 fetuses got missed diagnosis,the incidence of fetal structural abnormality was 5.16%.32 fetuses were diagnosed as severe structural abnormality among 78 fetuses with structural abnormality,accounting for 41.03%; 46 fetuses were diagnosed as mild structural abnormality among 78 fetuses with structural abnormality,accounting for 58.97%.The incidences of placental abnormality and amniotic fluid abnormality were 0.89% (15 fetuses) and 7.14% (119 fetuses),respectively.The coincidence rates of two-dimensional ultrasound and three-dimensional ultrasound among 1 667 high risk fetuses were 70.93% and 87.21%,respectively.Conclusion:Three-dimensional ultrasound can diagnose structural abnormality of high risk fetuses definitely,which is a vital method to reduce misdiagnosis rate,omission diagnostic rate and medical risk.
