摘要
目的探讨早孕期超声筛查异常行绒毛核型分析的意义。方法对65例早孕期超声筛查发现异常的孕妇行绒毛核型分析。结果在65例早孕期超声筛查异常孕妇的胎儿绒毛核型中,检出异常核型28例,异常率为43.08%,主要为18-三体、21-三体和45,X。在异常的超声指征中,全身皮下水肿7例,5例核型异常;全身皮下水肿合并其他异常9例,8例核型异常;胚胎停育11例,6例核型异常;鼻骨异常合并其他异常3例,2例核型异常;NT增厚18例,4例核型异常;NT增厚合并其他异常6例,4例核型异常;多发畸形8例,3例核型异常;淋巴水囊瘤1例有核型异常。结论早孕期超声筛查异常孕妇的胎儿染色体异常率高,对其行绒毛核型分析是必要的。
Objective: To study the significance of chorionic villus karyotype analysis for abnormal early pregnancy ultrasound screening.Methods: Chorionic villus karyotype analysis were done for 65 cases of abnormal early pregnancy ultrasound screening of pregnant women.Results: 28 cases of abnormal karyotypes were detected in 65 cases of fetal chorionic villus karyotypes from pregnant women with abnormal early pregnancy ultrasound screening.The abnormal rate was 43.08%,the mainly abnormal karyotypes were trisomy 18,trisomy 21 and 45,X.Of the indications of abnormal ultrasound systemic subcutaneous edema was found in 7 cases,5 cases of them had abnormal karyotypes;systemic subcutaneous edema associated with other abnormalities in 9 cases,8 cases with abnormal karyotypes;embryo damage in 11 cases,6 cases with abnormal karyotypes;nasal bone abnormalities associated with other abnormalities in 3 cases,2 cases with abnormal karyotypes;nuchal translucency thickening in 18 cases,4 cases with abnormal karyotypes;nuchal translucency thickening associated with other abnormalities in 6 cases,4 cases with abnormal karyotypes;multiple malformations in 8 cases,3 cases with abnormal karyotypes;lymph hygroma in 1 case with abnormal karyotype.Conclusions: Pregnant women with abnormal early pregnancy ultrasound screening had a high abnormal rate of fetal chromosome.It was necessary to do chorionic villus karyotype analysis for them.
