摘要 目的分析1 108例羊水穿刺结果揭示唐山地区胎儿异常染色体特点及临床高危因素。方法高危孕妇行羊膜腔穿刺术后羊水细胞培养及染色体核型分析。结果异常核型38例,检出率3.43%。异常核型中三体综合征15例,性染色体异常3例,平衡易位6例,倒位4例,其他10例。异常核型检出率中夫妇一方染色体异常组(46.15%)要高于高龄妊娠组(6.54%)和唐氏综合征高危组(1.29%);超声提示胎儿发育异常组(11.48%)也高于高龄妊娠组(6.54%)和唐氏综合征高风险组(1.29%),差异均有统计学意义(均P<0.01)。结论夫妇一方染色体异常及超声显示胎儿发育异常是唐山地区最主要的产前诊断指征,异常核型以21-三体综合征检出率最高。
