Cordocentesis


Definition:

Example Sentences:

  • (1) The following examinations could be proposed: in high risk cases determined before pregnancy, a chorionic villus sampling should be done between the 9th and 11th weeks of gestation; in low risk cases such as advanced maternal age, a first trimester chorionic villus sampling or a second trimester amniocentesis could be chosen; in the case of Down's syndrome, warning signs, for example ultrasonographic or biological parameters, a second trimester placental biopsy to relieve the parents' anxiety; in high risk cases such as ultrasonographic malformations, late placental biopsy or cordocentesis.
