Diagnostic value of the cerebroplacental ratio and the umbilical artery blood flow parameters detected by Doppler ultra-sound of pregnant women for their fetal growth restriction
Objective:To analyze the diagnostic value of the cerebroplacental ratio(CPR)and the umbilical artery blood flow detected by Doppler ultrasound of pregnant women for their fetal growth restriction(FGR).Methods:90 preg-nant women with FGR diagnosed by antenatal examination in hospital were selected in observation group,and 80 nor-mal pregnant women were selected in control group between July 2022 and July 2023.The values of umbilical artery pulsatilityindex(PI),resistance index(RI),maximum systolic blood flow velocity to end-diastolic blood flow velocity(S/D)ratio and CPR of the women in the two groups were detected by Doppler ultrasound.The adverse pregnancy outcomes of the women in the two groups were counted.The values of PI,RI,S/D and CPR,and the incidence of ad-verse pregnancy outcomes of the women were compared between the two groups.Receiver operator characteristic(ROC)curve was used to evaluate the predictive value of the values of PI,RI,S/D and CPR of the women for their FGR.Results:The PI,RI,S/D and CPR values of the women in the two groups had decreased with the increase of their gestational weeks.The values of PI,RI and S/D of the women in the observation group during 32-33+6 gestation-al weeks,34-36+6 gestational weeks and 37-40 gestational weeks were significantly higher than those of the women in the control group,and the CPR value of the women in the observation group was significantly lower(P＜0.05).ROC curve analysis showed that the area under the curve of the combination of the values of PI,RI,S/D and CPR of the women for diagnosing their FGR during 37-40 gestational weeks was 0.957,and the sensitivity of which was 97.5％,and both of which were significantly higher than those of the PI value,the RI value,the S/D value or the CPR value a-lone(P＜0.05).The rates of the neonatal asphyxia and low birth weight,and the neonatal Apgar score in the observa-tion group were significantly lower than those in the control group(P＜0.05).Conclusion:The CPR combined with umbilical artery blood flow parameters values of the pregnant women for diagnosing their FGR can increase the diagnostic efficacy and the diagnostic sensitivity.
