Abstract Objective To explore and analyze the relationship between uterine artery blood flow parameters and embryo abortion. Methods A retrospective analysis was performed on the clinical data of 138 pregnant women of 6-12 weeks of pregnancy admitted to Liaocheng Hospital of Traditional Chinese Medicine, Shandong Province from May 2018 to May 2021. They were divided into normal group (121 cases) and abortion group (17 cases) according to different developmental conditions. At the same time, the abortion group was divided into empty gestational sac group (7 cases) and embryo and no fetal heart group (10 cases). The uterine artery blood flow parameters were compared between normal group and abortion group at different gestational ages and different embryo types. Results Compared with the 6th week of pregnancy, the values of peak systolic / diastolic flow rate (S/D), resistance index (RI), and pulsatility index (PI) in the 9th and 12th weeks of pregnancy in normal group and abortion group were decreased, and the differences were statistically significant (P < 0.05); compared with the 9th week of pregnancy, the values of S/D, RI, and PI in the 12th week of pregnancy were decreased in normal group and abortion group, and the differences were statistically significant (P < 0.05). Compared with normal group, the values of S/D, RI, and PI in the 9th and the 12th weeks of abortion group were decreased, and the differences were statistically significant (P < 0.05). The gestational age of abortion group was negatively correlated with S/D, PI, and RI values (r = -0.978, -0.971, -0.990, P < 0.05). There were no significant differences in S/D and PI values at admission among three groups (P > 0.05). RI values at admission were significantly different among three groups (P < 0.05); compared with normal group, RI value at admission of embryo and no fetal heart group was lower, and the difference was statistically significant (P < 0.05). Conclusion Using vaginal color Doppler ultrasound to monitor uterine artery blood flow parameters has a high application value in embryo monitoring.
