摘要/Abstract

摘要： 探讨孕晚期胎儿生长受限（FGR）胎儿彩色多普勒超声（CDFI）血流参数对FGR的诊断价值。选取FGR的孕晚期孕妇110例为观察组，正常孕晚期孕妇110例为对照组，比较两组CDFI血流参数差异。结果显示，与对照组比较，观察组脐动脉PI、RI和S/D较高（P<0.05）；观察组大脑中动脉PI、RI和S/D明显低于对照组（P<0.05）；观察组主动脉弓峡收缩期末反流流速（ESRV）明显高于对照组（P<0.05）。脐动脉PI、RI和S/D，大脑中动脉PI、RI和S/D，以及ESRV诊断FGR的ROC曲线下面积中，大脑中动脉PI的ROC曲线下面积最大。说明CDFI血流参数在诊断FGR中有一定价值。

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.
