Abstract

Aims: To evaluate the impact of umbilical and uterine artery Doppler in the second and third trimester on antenatal course, labor and delivery in a low-risk primigravid population.

Methods: Prospective recruitment of 1011 low-risk primigravidas with uterine and umbilical artery Doppler assessment at 22–24 weeks and 36 weeks. All mothers and infants were reviewed postnatally with a retrospective analysis of ultrasound and clinical outcome data.

Results: Elevated uterine artery indices were associated with increased rates of threatened miscarriage, higher rates of pre-eclampsia (PET) and a higher incidence of fetal birth weight <2nd and 9th centile for gestation. Uterine artery pulsatility index (PI) >95th centile for gestation was associated with statistically higher rates of small-for-gestational age (SGA) infants. Elevated umbilical artery indices were associated with higher rates of induction of labor and a higher incidence of fetal birth weight infants <2nd and 9th centile for gestation. Umbilical artery PI >95th centile for gestation was associated with statistically higher rates of SGA infants.

Conclusion: Elevated uterine and umbilical artery indices are associated with higher rates of maternal and fetal disease.
