To find out the importance of uterine artery pulsatility index (PI) at 30–33 weeks gestation in detecting high risk pregnancy developing hypertension and SGA at advanced gestational age.
Methodology: The study carried out in Srinivas Institute of Medical Sciences and Research Centre and Mangalore Fetal Medicine Centre, from Dec 2016 to Nov 2017 and at 30–33 weeks gestation uterine artery Doppler performed in 952 singleton primigravida pregnancies and outcome recorded by follow up.
Results: Out of 952 pregnancies 920 patient were normal. 32 developed hypertension in pregnancy. Whereas 6 women developed PE requiring delivery 34- 37 weeks and 10 developed PE requiring delivery at or after 38 weeks 16 women developed Gestational hypertension.49 women developed SGA in absence of Hypertension.
Uterine artery mean PI> 1.10 detects high risk pregnancy developing intermediate, late PE and SGA.
Conclusion:Uterine artery PI at 30–33 weeks could effectively identify women at high risk for subsequent development of PE and SGA.
