Abstract To explore of uterine artery hemodynamic parameters measured by color Doppler ultrasound (CDUS) for predicting unexplained recurrent spontaneous abortion (URSA). Methods: The clinical data of 135 women with URSA from August 2015 to August 2019 (in study group), and the clinical data of 140 normal pregnant women during the same period (in control group) were analyzed retrospectively, and all of these women underwent CDUS examination. The uterine artery hemodynamic parameters, such as pulse index (PI), systolic peak velocity/ diastolic peak velocity (S/D), and resistance index (RI) of women were compared between the two groups and among women with different abortion times. The value of uterine artery hemodynamic parameters for predicting URSA were analyzed. Results: The values of PI, S/D,and RI of women in the study group were significant higher than those of women in the control group (P＜0.05). With the increasing of abortion times, the values of PI, S/D and RI increased gradually in study group. The results of multiple Logistic regression analysis showed that the high values of PI, S/D and RI would increase URSA risk (P＜0.05). ROC curves showed that AUC of PI, S/D and RI was 0.632, 0.768, and 0.853, respectively. Conclusion: The uterine artery hemodynamic parameters of women with URSA increase abnormally, which have value for predicting URSA, so they can be used for screening URSA.
