Abstract:
Objective To investigate the diagnostic value of three-dimensional power Doppler ultrasound(3D-PDUS)in fetal growth restriction(FGR).Methods A total of 120 pregnant women in the third trimester who were given birth in Wenzhou People's Hospital from September 2021 to December 2023 were selected as study objects,50 pregnant women with FGR confirmed by clinical and ultrasound were included in case group,and 70 pregnant women with normal fetal development were included in control group.The renal volume and renal blood flow parameters of the fetuses in two groups were compared.The pregnancy outcomes and perinatal conditions of two groups were compared.Receiver operating characteristic(ROC)curve was plotted to calculate the area under the curve(AUC),and the diagnostic efficacy of various blood flow parameters for FGR was evaluated.Results The renal volume/gestational week,renal vascularization index,vascularization flow index and renal artery peak systolic velocity of the fetuses in case group were significantly lower than those in control group,while renal artery peak systolic velocity/end diastolic velocity,pulsation index and resistance index were significantly higher than those in control group(P＜0.05).There was no significant difference in renal flow index between two groups(P＞0.05).ROC curve results showed that the diagnostic efficacy of renal volume/gestational week and renal artery peak systolic velocity were higher,while the diagnostic efficacy of combined application was the highest,with an AUC of 0.89.The rate of low birth weight infants in case group was significantly higher than that in control group,and neonatal Apgar score was significantly lower than that in control group(P＜0.01).Conclusion 3D-PDUS quantitative analysis parameters evaluated renal volume and blood perfusion could predict FGR,which is conducive to early diagnosis of FGR and guide clinical intervention,and effectively reduce adverse pregnancy outcomes.
