Abstract：Objective:To analyze the role and value of transvaginal color Doppler ultrasound(transvaginal color Doppler ultrasound)in the clinical differential diagnosis of ectopic pregnancy rupture and ovarian corpus luteum rupture.Method:Patients with ruptured ectopic pregnancy and ruptured corpus luteum of the ovary admitted to Taishan Maternal and Child Health Hospital from May 2022 to May 2024 were selected as the research subjects,with 62 cases and 53 cases respectively.All patients underwent vaginal color Doppler ultrasound examination.The color Doppler ultrasound indicators,blood flow characteristics,diagnostic efficacy and consistency of pathological diagnosis of patients with different diseases were compared and calculated.Result:The ovarian volume,depth of the fluid dark area and diameter of the abnormal echo area in ruptured corpus luteum of the ovary were higher than those in ruptured ectopic pregnancy,and the difference was statistically significant(P<0.05).The comparison of blood flow signal patterns in patients with the two diseases showed statistically significant difference(P<0.05).In the images of ruptured ectopic pregnancy,point-like and strip-like blood flow signals were mainly found,while in the images of ruptured corpus luteum of the ovary,there were more circular blood flow signals.Among the efficacy indicators of vaginal color Doppler ultrasound in the differential diagnosis of the two lesions,the accuracy was 95.65%,the sensitivity was 94.34%,the specificity was 96.77%,the positive predictive value was 96.15%,and the negative predictive value was 95.24%,and it had extremely high consistency with the pathological diagnosis(Kappa=0.912,P<0.05).Conclusion:The application of vaginal ultrasound in clinical examination and differential diagnosis of ectopic pregnancy rupture and ovarian corpus luteum rupture is accurate and effective.It has good application results.
