[Placentocentesis, a new technic in the prenatal diagnosis of chromosome aberrations in the 3d trimester. A preliminary study apropos of 5 cases].
The authors report 5 cases in which placentocentesis was used for late antenatal diagnosis between the 25th and 34th week of amenorrhoea. As the placenta was anteriorly placed, samples were obtained by aspiration through the abdominal route under ultrasound control. The fetal karyotype could be determined in 2 days using a direct method. It showed normal chromosome pictures in all 5 cases. There was no complication in any of these cases following the procedure.
