三维能量多普勒超声联合频谱多普勒超声对孕晚期胎儿生长受限的预测价值
Prediction Value of Three-dimensional Energy Doppler Ultrasound Combined with Spectral Doppler Ultrasound for Fetal Growth Restriction in the Third Trimester
摘要
Abstract
Objective:To explore the predictive value of 3D energy Doppler ultrasound combined with spectral Doppler ultrasound for fetal growth restriction(FGR)in late pregnancy.Methods:A total of 46 women in the third trimester who underwent prenatal examination in our hospital and were diagnosed with FGR after delivery from June 2020 to May 2023 were retrospectively included as the FGR group,and 46 women in the third trimester who were not FGR during the same period were included as the non-FGR group in a 1:1 ratio.The clinical data,placenta and newborn indexes were compared between the two groups.Cox proportional risk model was used to analyze the relationship between ultrasonic parameters and the occurrence of FGR.Receiver operator characteristics(ROC)curve was used to analyze the predictive efficiency of ultrasonic parameters to FGR.Results:Neonatal weight,placental vascularization index(VI)and vascularization blood flow index(VFI)of the FGR group were significantly lower than those of the non-FGR group.And pulse index(PI),resistance index(RI)and systolic peak blood flow velocity/diastolic peak blood flow velocity(S/D)were significantly higher than those in non-FGR group(P＜0.05).With the decrease of VI and VFI levels and the increase of S/D,PI and RI levels,the correlation effect with FGR events was stronger.ROC curve analysis results showed that VI,VFI,S/D,PI and RI had predictive value in the diagnosis of FGR alone and in combination,and the combined prediction value was the highest.Conclusion:Three-dimensional energy Doppler ultrasound combined with spectral Doppler ultrasound has a better prediction effect on FGR in pregnant women in the third trimester,and has high clinical application value.关键词
