[Fetal karyotyping of fetal blood obtained from the umbilical vein using ultrasound].
The fetal karyotype was established during the second or third trimester of 18 at risk pregnancies after fetal blood sampling by direct puncture of the umbilical vein guided by real time ultrasound. Two karyotypes were abnormal. This rapid technique for karyotyping allows the obstetrician to decide early how the pregnancy should be conducted.
