Value of detecting uterine artery blood flow with ultrasound to predict early-onset preeclampsia in second trimester

Abstract

Objective To investigate the practical value of monitoring uterine hemodynamics with ultrasound during second trimester in clinical diagnosis and treatment on early-onset preeclampsia.Methods Doppler ultrasound was given to observe PI,RI and S/D of uterine arteries in 20-23+6 weeks and 24-28 weeks for all pregnant women,follow up observation was conducted to pregnant women during pregnancy and childbirth,then we compared the group uterine artery blood flow parameters of early-onset preeclampsia with normal pregnancy.Results According to pregnancy outcomes,access to 21 cases of early-onset preeclampsia and 40 cases of normal control group,patients with early-onset preeclampsia had higher uterine arterie PI,RI and S/D than the those of normal control group in 20-23+6 weeks and 24-28 weeks,the difference has statistical significance,P ＜ 0.05.Conclusion The early-onset preeclampsia compared with normal,uterine artery blood flow velocity of pregnant women is quite different,uterine artery blood flow parameters can be used as a secondary indicator to assist clinicians of screening risk populations with early-onset preeclampsia during second trimester.
