Abstract Objective:To analyze the value of color Doppler ultrasound detection of fetal umbilical artery (UA) and middle cerebral artery (MAC) blood flowin late pregnancy on the evaluation of fetal growth restriction (FGR). Methods:120 cases of pregnant women in late pregnancy who were examined in our hospital from June 2016 to March 2018 were selected. Among them, 30 cases suspected as FGR by preoperative routine ultrasound were set as observation group, and other 90 cases without abnormalities were selected as control group. The two groups were given color Doppler ultrasound. The differences in UA and MAC blood flow parameters were compared, and they were followed up until the end of pregnancy, and the pregnancy outcomes of fetuses were compared between the two groups. Results: The UA EDV in observation group was significantly lower than that in control group (P<0.05) while the UA PI, RI, PSV/EDV and MCA PSV were higher than those in control group (P<0.05), and there was no significant difference in UA PSV and MCA EDV, PI, RI and PSV/EDV (P>0.05). The incidence rates of fetal distress, neonatal asphyxia, premature delivery and deathin observation group were significantly higher than those in control group (P<0.05). Conclusions: Color Doppler ultrasound can evaluate FGR and prognosis in late pregnancy by detecting UA and MAC blood flow of fetus in late pregnancy, and provide reliable basis for effective clinical intervention.
