(18) One week after cordocentesis, the vessel wall was partially reformed.
(19) In all cases cordocentesis was performed within 24 hours before delivery for the measurement of umbilical venous blood gases.
(20) In order to obtain more rapid karyotypes, cordocentesis rather than amniocentesis was performed.
