Purpose of Study
To study the predictive accuracy of maternal characteristics, mean arterial pressure, uterine artery doppler and maternal ophthalmic artery doppler in second trimester for subsequent development of pre-eclampsia.
Methods
A prospective cohort study of 440 women at 19–24 weeks’ gestation. It included recording of maternal demographic characteristics and calculation of HDP Gestosis Score, measurement of MAP and ultrasound evaluation for fetal anatomy, Uterine artery doppler and maternal ophthalmic artery doppler. The mean Peak Systolic Velocity ratio was obtained by taking two sets of reading from both eyes. The statistical analysis was done using independent t-test for quantitative variables and chi-square test, Fisher’s exact test for qualitative variables and Area Under Curve was obtained at 10% False Positive Rate.
Results
Among 440 pregnant women, 43(10.8%) developed Hypertensive Disorder of Pregnancy (8 early onset PE, 16 late onset PE and 19 GHTN) and 42 were lost to follow up, with an incidence rate of 10.8%. Combination of Gestosis Score + OAD PSV Ratio had highest AUC of 0.73. Whereas combination of Gestosis Score + MAP + UtAPI + OAD-PSV Ratio had highest sensitivity of 97.67%. The OAD PSV ratio improved detection rate of Gestosis Score (from 90 to 100%) for prediction of development of PE, especially Preterm PE at 10% FPR.
Conclusion
Maternal Ophthalmic artery doppler study significantly improved prediction of development of PE at 19–24 weeks’ gestation, both independently as well as in combination with HDP-Gestosis Score, MAP and uterine artery doppler.
