Prognostic role of uterine artery Doppler in early- and late-onset preeclampsia with severe features

Objective To correlate uterine artery Doppler findings with maternal and neonatal outcomes in early- and late-onset preeclampsia with severe features. Methodology Doppler scan was done in both uterine arteries. Maternal and neonatal outcomes in women with abnormal and normal Doppler results were compared. Results Abnormal Doppler results were present in 45 women (75%). Thirty-four (56.7%) women had abnormal RI, 19 (31.6%) had abnormal PI, and 36 (60%) had diastolic notch. Of the women who participated in the study, 21.6% developed maternal complications, and the majority belonged to the early-onset severe preeclampsia group. Diastolic notch was twofold more frequent in the early group. RI was abnormal in 63% of the early-onset and 50% of the late-onset group. Conclusion Pregnancies with early-onset preeclampsia who had abnormal uterine artery Doppler findings were at high risk for both maternal and neonatal complications, whereas those who had late-onset preeclampsia with abnormal Doppler findings only had an increased risk of perinatal complications.
