Diagnostic Value of Color Doppler Flow Parameters in Fetal Growth Restriction

doi:10.7517/issn.1674-0475.201102

Abstract

Abstract: The purpose of this study was to investigate the diagnostic value of the blood flow parameters by color Doppler flow imaging (CDFI) in late pregnancy with fetal growth restriction (FGR). A total of 110 cases of third trimester pregnant women with FGR were selected as observation group, and 110 cases of normal pregnant women in the third trimester were selected as the control group. The differences in CDFI blood flow parameters between the two groups were compared. The experimental results showed that,compared to the control group, the PI, RI and S/D of umbilical artery in the observation group was higher. The PI, RI and S/D of the middle cerebral artery in the observation group were significantly lower than those in the control group (P<0.05). The end systolic reflux velocity (ESRV) of aortic arch isthmus in the observation group was significantly higher than that in the control group (P<0.05). The area under the ROC curve of umbilical artery PI, RI and S/D, middle cerebral artery PI, RI and S/D, and ESRV in diagnosing FGR, the area under ROC curve of middle cerebral artery PI was the largest. CDFI blood flow parameters have certain value in the diagnosis of FGR.
