Flow velocity waveforms of the ductus arteriosus in appropriate and small-for-gestational-age fetuses.

OBJECTIVES To assess ductus arteriosus velocity waveforms in the appropriate and small-for-gestational-age (SGA) fetuses. STUDY DESIGN Ductus arteriosus flow velocity waveforms were obtained in 14 normal fetuses in a longitudinal study and in 139 normal fetuses in a cross-sectional study with pulsed and continuous Doppler ultrasonography. Ductus velocity… CONTINUE READING
