Abstract

 

Umbilical artery Doppler assessment is an important marker of uteroplacental insufficiency and consequent intrauterine growth restriction therefore assessment of normal values is key in early detection of these anomalies. This cohort study was carried out on 222 pregnant Nigerian women in a private hospital in Port Harcourt Nigeria. Duplex color Doppler sonography was utilized in measurement of Pulsatility Index (PI), Resistivity index (PI) and systolic/diastolic (S/D) ratio of the umbilical artery of fetuses during the 2nd and 3rd trimesters. The age range was from 20-45 years with a mean age of 28.3 ± 1.8. The mean values and standard deviations (SD) of the PI and RI value of the umbilical artery in the 2nd and 3rd trimester were 1.05 (SD ± 0.24) and 0.63 (SD ± 0.10) respectively. In separate trimesters the mean value of PI in the 2nd trimester was 1.10 (SD ± 0.25), RI 0.6 (SD ± 0.12) and in the 3rd trimester PI 0.98 (SD ± 0.23), RI 0.5 (SD ± 0.07). There was significant difference between mean values of PI in different gestational ages (t=3.76, level of significance=0.000), PI value decreased with increasing gestational age (r=-0.027) but not statistically significant (p=0.112). Normal reference values of the umbilical artery doppler velocimetry in our environment has been documented and shows a normal variation of umbilical artery velocimetry in 2nd and 3rd trimester gestation with advancing gestational age.
