用羊水细胞培养进行产前诊断,为期常需数周。但是,胎儿的染色体组型有时须于数天内确诊。为此,本文介绍一种于72小时内完成胎儿染色体分析的方法。作者研究分析了14例妊娠116～23周的胎儿。其中13例孕妇因治疗性流产而住院,其中一例曾行羊膜穿刺诊断为18三体。另有1例孕妇因曾生产一患Down综合征的小孩,而须行产前诊断。 Prenatal diagnosis with amniotic fluid cell culture often takes weeks. However, the fetal karyotype may sometimes be diagnosed within days. To this end, this article describes a method for completing fetal chromosomal analysis within 72 hours. The authors analyzed 14 fetuses between 116 and 23 weeks of gestation. Among them, 13 cases of pregnant women were hospitalized for treatment of abortion, one of them had amniocentesis diagnosed as 18 trisomy. Another case of pregnant women who had had a syndrome of Down syndrome, but prenatal diagnosis.
