目的探讨产前超声检查在胎儿畸形的诊断中作用。方法收集我院2005年1月至2009年12月产前常规行超声检查9350例,其中检出胎儿畸形98例,并对胎儿畸形情况进行分析总结。结果通过超声检查,胎儿畸形检出率为1.05%,产前超声诊断98例胎儿畸形情况和最后诊断符合率100%。漏诊3例,漏诊率3.09%。结论先天性胎儿畸形是胎儿形态上的结构异常改变,超声能发现先天性胎儿畸形,先天性胎儿畸形各型各有自己的超声特征,同时可及早发现部分致死性和非致死性畸形,故超声检查是产前诊断胎儿畸形的首选方法。
Objective To investigate the role of prenatal ultrasound in the diagnosis of fetal malformations. Methods Nine hundred and fifty-five cases of ultrasound examination in our department from January 2005 to December 2009 were collected. Among them, 98 cases of fetal malformations were detected and the abnormality of fetus was analyzed and summarized. Results Ultrasound examination showed that the detection rate of fetal malformations was 1.05%. The prenatal ultrasound diagnosis of 98 cases of fetal malformations and the final diagnosis of 100%. Misdiagnosis in 3 cases, missed diagnosis rate of 3.09%. Conclusions Congenital fetal malformations are abnormal morphological changes of the fetus. Ultrasound can detect congenital fetal malformations. Each type of congenital fetal malformations has its own ultrasonic characteristics. At the same time, some fatal and nonfatal deformities can be found early, so ultrasonography Check is the preferred method of prenatal diagnosis of fetal malformations.
