Screening for chromosomal abnormalities at 10–14 weeks: the role of ductus venosus blood flow

1 Dec 1998

Abstract excerpt

OBJECTIVE: To assess the possible role of Doppler ultrasound assessment of ductus venosus blood flow in screening for chromosomal abnormalities at 10-14 weeks of gestation. METHODS: Ductus venosus flow velocity waveforms were obtained immediately before fetal karyotyping in 486 consecutive singleton pregnancies at 10-14 weeks of gestation. All cases were screened for chromosomal defects by a combination of...
