Abstract To study the diagnostic value of the pulsatility index (PI)value and the corpora luteum graviditatis situation examined by ultrasound for tubal ectopic pregnancy of women, and to analyze the risk factors of tubal ectopic pregnancy of the women. Methods: 101 women with tubal ectopic pregnancy diagnosed and treated in hospital were selected in research group from February 2017 to January 2022. 100 cases of intrauterine pregnancy were selected in control group during the same period. The values of uterine artery resistance index (RI), PI, peak systolic velocity (PSV), and end diastolic velocity (EDV)examined by ultrasound of the women were compared between the two groups. The situation of corpora luteum graviditatis of the women in the research group were compared between the same side of the fallopian tube and the different side of the fallopian tube, and between the fallopian tube with function and the fallopian tube without function. The values of the PI values of uterine artery and fallopian tube, and the situation of corpus luteum graviditatis of the women for diagnosing their tubal ectopic pregnancy was analyzed, and the risk factors of ectopic tubal pregnancy were also analyzed. Results: The values of RI and PI of the women in the research group were significantly lower than those of the women in the control group, while the values of PSV and EDV of the women in the research group were significantly higher than those of the women in the control group. The uterine artery PI value in the same side of the fallopian tube of the ectopic pregnancy (4.19±1.11)of the women in the research group was significantly lower than that (19.74±5.29)in the different side of the fallopian tube, and which (2.62±0.19)in the fallopian tube with function of the women in the research group was significantly lower than that (2.77±0.25)in the fallopian tube without function (all P＜0.05). Receiver operating characteristic (ROC)curve analysis showed that the combined values of uterine artery and fallopian tube PI, and the situation of corpora luteum graviditatis of the women could improve their diagnostic efficiency for tubal ectopic pregnancy. The critical value of the uterine artery PI value ≤2.22, and the changes of the values of the corpora luteum graviditatis, and the value of tubal PI ≥0.18, the salpingitis, the pregnancy ≥3 times, and the intrauterine device (IUD)inserted were all the risk factors of tubal ectopic pregnancy. Conclusion: The changes of the uterine artery PI value and the situation of corpora luteum graviditatis examined by ultrasound have higher diagnostic value for tubal ectopic pregnancy. The women with salpingitis, pregnancy ≥3 times, or IUD inserted should be as the focus of attentional objects.
