The direct preparation of chromosomes in early pregnancy with microvilli is a new method of early prenatal diagnosis in utero.We report the clinical application of direct preparation of chromosomes in 94 cases of early microvilli in early pregnancy.The results show that the success rate of early intrauterine diagnosis of prenatal diagnosis is 80% Follow-up (1 case lost to follow-up) resulted in only one child being delivered with different karyotype and karyotype, while all other infants were normal, indicating that this method is simple, rapid and safe and can be applied clinically.
