目的胎儿畸形种类多,有些畸形在不同的孕期易被检查出来,在多年的工作中,笔者对胎儿进行全面系统的检查,共检查出畸形胎儿18例,从而探讨出在中孕期检查可以提高胎儿畸形的检出率。方法自2003年5月至2008年8月在本院彩超检查的孕妇中,对检出的畸形胎儿进行统计,分别统计出中孕期及晚孕期胎儿畸形的检出率,并对漏诊的畸形儿进行分析总结,从而得出检查胎儿畸形最好在中孕期。结果在彩超检查的4663例孕妇中,共检出各种胎儿畸形18例,检出率为3.86‰中孕期检出16例,检出率为3.43‰,晚孕检出2例,检出率为0.43‰,漏诊2例,均为晚孕期漏诊,漏诊率0.43‰。结论中孕期(孕12～28周)胎儿畸形检出率高,建议孕妇在中孕期做两次彩超检查,最好晚孕期复查1次。
Objective Fetal malformations and more, some deformities in different pregnancy is easy to be checked out, in many years of work, the author of a comprehensive and systematic examination of the fetus, a total of 18 cases of abnormal fetus checked to explore in the second trimester can improve fetus The detection rate of deformity. Methods From May 2003 to August 2008 in our hospital color Doppler ultrasound examination of pregnant women, the fetus were detected in the statistics were statistics of the second trimester pregnancy and fetal malformations were detected, and misdiagnosis of missing children To analyze and conclude, which leads to check the best fetal malformation in the second trimester. Results Among the 4663 pregnant women examined by color Doppler ultrasound, 18 cases of various fetal malformations were detected, with a detection rate of 3.86 ‰. 16 cases were detected during pregnancy, with a detection rate of 3.43 ‰ and 2 cases of late pregnancy, the detection rate 0.43 ‰, 2 cases of missed diagnosis, missed diagnosis in late pregnancy, the rate of missed diagnosis was 0.43 ‰. Conclusion The detection rate of fetus deformity in middle pregnancy (12 ~ 28 weeks pregnant) is high. It is suggested that pregnant women do color Doppler ultrasound examination in the second trimester.
