title: [Karyotyping of fetal cells in the prenatal diagnosis in Costa Rica].
abstract: The results of 182 genetic amniocenteses between 14 and 37 weeks gestation, from 1986 to 1992, and of two cordocenteses in 1992, are reported. There were two main reasons for referral: maternal age 35 years and older and abnormal ultrasound assessment. Fetal cells were closed cultured and mass harvested. In 3.7% of cases fetal chromosomes were defective. Turn around time was about three weeks up to and including 1991 and two weeks in 1992, culture failure rate was 7% that year. No cytogenetic misdiagnosis and no complication or sequelae related to the amniocenteses were detected. We conclude this is a safe and reliable procedure to obtain fetal karyotypes and to improve obstetric management of high-risk pregnancies.
