摘　　要：目的探讨胎儿畸形超声检查的声像图特征以及临床价值,并分析超声检查对畸形胎儿诊断的局限性。方法对2018年1月~7月来我院13491例的11~36w(分为三阶段,第一阶段孕早期为11~13+6w,第二阶段孕中期为18~24w,第三阶段孕晚期为32~36w)孕妇进行二维、三维超声检查,对检查中发现的167例胎儿畸形进行声像图特征、临床价值、诊断局限性进行回顾性分析。结果经引产或分娩证实胎儿畸形175例,产前检查出167例,漏诊8例,超声诊断准确率95.4%,漏诊率4.6%。胎儿畸形分为4种类型:形态结构异常124例、细胞异常19例、代谢异常11和染色体异常21例。结论超声检查是产前诊断的主要方法,结合胎儿畸形声像图特征对胎儿畸形做出早期判断,对优生优育具有重要的临床价值,但同时也有一定的局限性。Objective:To investigate the sonographic features and clinical value of fetal malformation by ultrasonography,and to analyze the limitations of ultrasonography in the diagnosis of malformed fetuses. Methods:From January to July 2018,13491 cases of our hospital were 11~36 weeks(divided into three stages,the first stage was 11~13+6 weeks in the first stage,and the second stage was 18~24 weeks in the second trimester. The third stage of the third trimester was 32~36 weeks. The pregnant women underwent two-dimensional and three-dimensional ultrasonography. The sonographic features,clinical value and diagnostic limitations of 167 fetal malformations found in the examination were retrospectively analyzed. Results:175 cases of fetal malformation were confirmed by induction or delivery,167 cases were prenatally examined,and 8 cases were missed. The accuracy of ultrasound diagnosis was 95.4%,and the rate of missed diagnosis was 4.6%. There are 4 types of fetal malformations:124 cases of abnormal morphological structure,19 cases of abnormal cells,11 cases of metabolic abnormalities and 21 cases of chromosomal abnormalities. Conclusion:Ultrasonography is the main method of prenatal diagnosis. It combines the characteristics of fetal malformation to make early judgments on fetal malformation. It has important clinical value for prenatal and postnatal care,but it also has certain limitations.
