Abstract
Objective: To compare the maternal and fetal characteristics and perinatal outcome in mild and severe preeclampsia cases with and without uterine artery Doppler abnormalities.
Methods: Two hundred and fifty-nine mild and severe preeclampsia cases were evaluated retrospectively. Doppler measurements were done in the section where uterine artery raised from the hypogastric artery. Pulsatility index above the 95th percentile of the corresponding gestational age was accepted as abnormal.
Results: In mild and severe preeclampsia cases with abnormal Doppler (AD), the rate of intrauterine growth restriction, preterm birth and low birth weight was higher than, but the neonatal intensive care unit stay was similar to the cases with normal Doppler. Base excess was higher in the AD group, in mild and severe preeclampsia. The rate of low Apgar score at 5 min and perinatal mortality was higher in the AD group, in the mild preeclampsia. The strongest independent predictor of the perinatal morbidity and mortality was the presence of prematurity and of the prematurity was the presence of abnormal uterine artery Doppler.
Conclusions: Maternal and perinatal morbidity and perinatal mortality increase in mild to severe preeclampsia cases with abnormal uterine artery Doppler. The abnormal uterine artery Doppler increases the morbidity and mortality by increasing the risk of prematurity.
