Abstract Objective: To analyze the value of blood flow parameters of chorionic trophoblastic artery by transvaginal Doppler ultrasonography for predicting the outcomes of women with threatened abortion. Methods: The pregnant women with threatened abortion were selected and were divided into group A (women with continuous pregnancy) and group B (women with inevitable abortion) according to the followed up results. In addition, normal pregnant women were selected in group C. The blood flow parameters of the trophoblastic chorionic artery of women in the three groups were examined by transvaginal two and three dimensional color Doppler ultrasound. Results: The values of S/D and RI of the chorionic trophotrophic artery of women in group B were significant higher than those of women in group A and C (P<0.001), but which of women in group A had no significant different from that of women in group C (P>0.05). There was no significant different in the PI value of the chorionic trophotrophic artery of women among the three groups (P>0.05). The values of VI, FI and VFI of the choriotrophotrophic artery of women in group B were significant lower than those of in group A and C (P<0.001). The values of FI and VFI of women in group A were significant lower than those of in group C (P<0.05), but there was no significant different in the VI value of the chorionic trophotrophic artery of women among the three groups (P>0.05). The values of RI, FI and VFI of chorionic trophotrophic artery could predict the outcomes of women with threatened abortion, which’s area under the ROC curve was 0.70.9 (P<0.001). The values of S/D and VI could not predict the outcomes of threatened abortion (P> 0.05). Conclusion: The RI, FI and VFI value of the chorionic trophotrophic artery of pregnant women by transvaginal Doppler ultrasound has some reference value for evaluating the outcomes of women with threatened abortion, which is worthy of application.
