Abstract Objective:To observe the relationship between uterine arterial blood flows by vaginal color doppler ultrasonography and the prognosis of pregnant women at first stage with threatened abortion. Methods: The data of pregnant women at first stage with threatened abortion in maternal and children health care hospital of BeiLun district of Ningbo city were analyzed retrospectively, and all included women were divided into group A (pregnancy lasted equal to or over 16 gestational weeks) or group B (pregnancy lasted less than 16 gestational weeks) according to the outcomes of pregnancy, and during the same time, the normal early pregnancy women were selected into group C. The uterine artery blood flow mechanics parameters, such as values of S/D, RI and PI of pregnant women were compared on among the three groups, and values of S/D, RI and PI were also compared between pregnant women less than 10 gestational weeks and pregnant women at 10 to 12 gestational weeks. The correlation of values of S/D, RI and PI to pregnancy outcomes were analyzed. Results: The values of S/D and RI of uterine artery blood flow indexes of women were different among the three groups, in which value of S/D of women in group A had no significant different to that of women in group C (P>0.05), but there was significant different in value of S/D of women among the other groups (P<0.05). The value of PI had no statistical different among the three groups. When the gestational weeks was less than 10, the values of S/D, RI, and PI of women were different among the three groups, in which values of S/D and PI of women in group A had no significant different to those of women in group C (P>0.05), but there were significant different in value of S/D and PI of women among the other groups (P<0.05). When women at 10-12 gestational weeks, the value of RI of uterine artery blood flow was different among the three groups, in which value of RI of women in group A had no significant different to that of women in group C (P>0.05), but there was significant different in value of S/D of women between group B and group A or group C (P<0.05). The values of S/D and PI had no statistical different among the three groups. The S/D and RI values were the high risk factors of the prognosis of pregnant women with threatened abortion during early stage (OR=5.895, 2.535, P=0.001, 0.009), but the value of PI had no impact on prognosis of pregnant women with threatened abortion. Conclusion: The indicators of uterine artery blood flow maybe have predictive value to the prognosis of pregnant women with threatened abortion during early stage, especially to pregnant women with threatened abortion less than gestational weeks, so these indexes can provide some evidences for clinical spuc treatment.
