Abstract:
Objective To explore indicator value of blood flow of uterine arteries in second trimester uterine artery by Doppler ultrasound and early diastolic notch in the prediction of preeclampsia development,and to analyze the relationship between these values and pregnancy outcomes and neonatal prognosis.Methods A total of 89 puerperae cases with preeclampsia underwent pregnant examinations in our hospital were retrospectively reviewed,and were divided into mild preeclampsia (group A) and severe preeclampsia (group B),and 100 women with normal singleton pregnancies were selected as control group(Group C).Four-dimensional ultrasound was adopted to detect pulsatility indices (PI),resistance indices (RI) and early-diastolic notch of bilateral uterine arteries in the three groups from 20 to 26 gestational weeks.The pulsatility index (PI) and resistance index (RI) of the uterine artery were measured,and the number of early diastolic waves was recorded.The relationship between these values and the outcomes of pregnancy and neonates was analyzed.Results Neonatal prognosis of Group B was worse than that of group A and group C (P ＜ 0.05);The uterine artery PI and RI of group B were higher than that of group A and group C (P ＜ 0.05).The early diastolic notch of group A and group B was higher than that of group C (P ＜ 0.05).Conclusion The indicator value of blood flow in uterine artery and the early diastolic notch in the second trimester could monitor the occurrence of preeclampsia,especially severe preeclampsia and they are useful to predict preeclampsia severity and prenatal prognosis.
