【摘要】 为在孕中期产前诊断胎儿染色体异常，防止患有染色体病的胎儿出生，对８５例有产前诊断适应症的孕１３～３２周孕妇抽取羊水细胞培养，进行胎儿染色体Ｇ带核型分析。结果表明，羊水细胞培养成功率９４．３％，检出染色体异常５例（异常率５．９％）。其中，９号染色体臂间倒位３例，１３、１４号染色体罗伯逊易位并１４号染色体臂内倒位１例，常染色体部分三体（４７，ＸＹ，＋ｍａｒ）１例。已进行产前诊断的胎儿分娩后随访证实了产前诊断结果。更多还原

【Abstract】 85 pregnant women in 13-32 pregnant weeks who had been selected mainly by their reproductive histories were enrolled to take prenatal diagnosis for fetal chromosomes to detect whether their fetus had the risk of suffering chromosomal disease. Amnio fluid cell culture and G-banding karyotype analysis were performed. It was shown that the success rate of amnio fluid cell culture was 94, 3%, and 5 cases with abnormal chrmosomes were detected.更多还原
