Umbilical cord puncture: when and why?

The umbilical cord puncture (chordocentesis) is a prenatal diagnostic procedure in which the child’s blood is obtained from the umbilical cord through a hollow needle. The analysis of the material allows statements to be made about the child’s chromosome set and thus possible diseases and chromosomal anomalies. It is an alternative to amniocentesis and chorionic villus sampling.
