Abstract To study the correlation between the values of peak systolic velocity (PSV), peak diastolic velocity (PDV), and resistance index (RI) of uterine artery detected by three-dimensional power Doppler ultrasound of women with polycystic ovary syndrome (PCOS) and their endometrial thickness and endocrine hormone levels. Methods: 120 women with PCOS who had been diagnosed and treated from January 2019 to February 2020 were collected in research group retrospectively, which included 35 women with menopause duration of 15-20 days in group A, 29 women with menopause time of 20-30 days in group B, 25 women with menopause duration of 30-60 days in group C, and 31 women with menopause duration of 60-90 days in group D. Another 120 volunteers with regular menstrual cycle who underwent physical examination during the same period were selected in control group. The differences of the PSV, PDV, and RI values, and the sex hormone levels of the women were compared between the research group and the control group, and among group A, B, C, and D. The correlations between the PSV, PDV, and RI values of the women with PCOS and their levels of luteinizing hormone (LH), testosterone (T), follicle- stimulating hormone (FSH), estradiol (E2), and progesterone (P) were analyzed. Results: The levels of serum FSH and P of the women in the research group were significantly lower than those of the women in the control group, the levels of T, LH, and E2 of the women in the research group were significantly higher than those of the women in the control group, and the endometrial thickness of the women in the research group was significantly higher than that of the women in the control group. The levels of serum FSH and P of the women in group A, B, C, and D had decreased gradually, while the levels of LH, T, and E2, and the endometrial thickness of the women in group A, B, C, and D had increased gradually. The values of PSV and PDV of the women in the research group were significantly higher than those of the women in the control group, but the RI value of the women in the research group was significantly lower. The values of PSV and PDV of the women in group A, B, C, and D had increased gradually, but the RI value of the women in group A, B, C, and D had decreased gradually (all P＜0.05). The levels of serum FSH and P of the women with PCOS were positively correlated with their PSV and PDV values and their duration of menopause, but which were negatively correlated with their RI value. The levels of LH, T, and E2 of the women with PCOS were negatively correlated with their PSV and PDV values and their duration of menopause, but which were positively correlated with their RI value (all P＜0.05). Conclusion: The values of PSV, PDV, and RI of the women with PCOS change abnormally, which are correlated with the changes of their sex hormone levels and their endometrial change. The monitoring of the ovarian blood flow of the women with PCOS can provide reference for their clinical treatment.
