Objective
To observe the role of uterine artery Doppler flow velocimetry at midtrimester in prediction of preeclampsia.
Method
179 women carrying <16 weeks of pregnancy, with singleton fetus and without any fetal anomaly were recruited and were divided in high-risk and low-risk group. Doppler velocimetry of uterine artery was done at 24–26 weeks. Any notch in uterine artery, unilateral or bilateral, or RI > 0.6, was considered abnormal. Women were followed up and development of preeclampsia noted.
Result
Sensitivity and specificity of abnormal uterine artery Doppler study for prediction of preeclampsia were 73.33 and 86.48 % in high-risk and 57.14 and 95.83 % in low-risk group, respectively. Relative risk with 95 % confidence interval was 5.427 (2.272–12.958) in high-risk and 13.65 (5.669–32.865) in low-risk women.
Conclusion
Doppler velocimetry of uterine artery at 24 weeks can be used as a reliable screening test for prediction of preeclampsia in both high-risk and low-risk women.
