[Umbilical artery doppler velocimetry indices in fetuses with single umbilical arteries]

ABSTRACT

Backgrounds and Objectives: Doppler waveform analysis of the umbilical artery is a powerful tool to evaluate probable pregnancy risks. So far, huge amounts of data on fetuses with three-vessel umbilical cords have been collected. Our objective was to evaluate the value of umbilical artery Doppler velocimetry in fetuses with single umbilical arteries. In this respect, two evaluation indices of the Pulsatility Index and the Systolic/Diastolic Ratio were considered
