Analysis on the Value of Two-Dimensional Ultrasound Combined with Color Doppler Flow Imaging in Screening Fetal Congenital Heart Malformation in Early Pregnancy
Objective To analyze the screening value of two-dimensional ultrasound combined with color Doppler flow imaging in early pregnancy for fetal congenital heart malformation.Methods 2 938 high-risk pregnant women were examined by two-dimensional ultrasound and color Doppler flow imaging in early pregnancy.The results of fetal congenital heart malformation were counted,and the diagnostic efficacy of two-dimensional ultrasound combined with color Doppler flow imaging in early pregnancy for fetal congenital heart malformation was evaluated.Results There were 53 cases of fetal heart malformation in 2 938 high-risk pregnant women,with the incidence rate of 1.80％.The sensitivity,specificity and accuracy of two-dimensional ultrasound combined with color Doppler flow imaging in the diagnosis of fetal congenital malformations in early pregnancy were higher than those of two-dimensional ultrasound in early pregnancy(P＜0.05).Conclusions Two-dimensional ultrasound combined with color Doppler flow imaging in early pregnancy has high sensitivity,specificity and accuracy in screening fetal congenital heart malformation.
