摘要
目的分析妊娠中期进行产前诊断的高危孕妇羊水细胞染色体核型,了解此期异常核型出现的频率及类型。方法 6887例具备产前诊断指征的妊娠妇女,在知情选择的情况下行羊膜腔穿刺术及染色体核型检测。结果 6876例羊水细胞培养成功,成功率为99.84%(6876/6887)。在6876例羊水细胞培养成功的染色体核型中,检出异常核型107例,异常率为1.56%,常见核型为三体型,占异常核型47.66%。结论羊水细胞学检查作为一项产前诊断技术对于指导优生优育,降低缺陷儿的出生具有重要意义。
Objective : To analysis the amniotic fluid cells chromosome karyotypes of high - risk pregnant women for prenatal diag- nosis and understand the frequencies and types of chromosomal abnormalities in the trimester period. Methods : Fetal chromosomal kar- yotypes were examined in 6887 pregnant women with amniotie cell culture. We studied in abnormal rate of fetal chromosomal karyotypes, searched the distribution of chromosomal abnormalities. Results: The success rate of amniotic cell culture was 99. 84% (6876/6887). One hundred and seven cases chromosomal aberrations were detected in 6876 cases and the abnormal rate was 1.56%. Of which, 51 cases were trisomy (47.66% , 51/107 ). Conclusions: As a prenatal diagnostic techniques for guiding prenatal, postnatal care and reducing birth defects in children, amniotic fluid cytology is very important.
