Predictive value of the uterine cavity ultrasound indexes for the complete abortion of patients with miscarriage treated by the medical abortion during the first trimester of pregnancy
Objective:To investigate the predictive value of the uterine cavity ultrasound indexes for the complete abor-tion of patients with miscarriage treated by the medical abortion during the first trimester of pregnancy.Methods:The data of the uterine cavity ultrasound indexes,such as the endometrial thickness,the diameter of heterogeneity echo mass in uterine cavity and the intrauterine Doppler blood flow,of the patients with miscarriage treated by medical a-bortion in 24 hours after treatment from January 2018 to December 2023 were collected.These patients with miscar-riage treated by medical abortion were divided into group A(patients with complete abortion)and group B(patients with incomplete abortion)according to the treatment outcomes.Multivariate logistic regression analysis was used to analyze the ultrasound indicators of the incomplete abortion of the patients with miscarriage treated by medical abor-tion.Results:There were significant differences in THE body mass index value,the previous pregnancy loss history,the number of abortion,the endometrial thickness,and the average diameter of the heterogeneity echo mass of the pa-tients between the two groups(t=4.880,x2=22.587,x2=21.018,t=5.081,t=4.890,and P＜0.001),and there was also significant difference in the uterine blood flow by Doppler of the patients between the two groups(x2=8.501,P＜0.05).Multivariate logistic regression analysis showed that the endometrial thickness of the patients was an inde-pendent risk factor for their incomplete medical abortion(OR=1.194,95％CI 1.116-1.278).The optimal threshold,the sensitivity and the specificity of the endometrial thickness by ultrasonic examination of the patients for predicting their incomplete medical abortion were 19.1 mm,60.5％and 95％,respectively.Conclusion:This study finds that the endometrial thickness by the uterine cavity ultrasound of the patients with miscarriage in 24h after the medical abortion is related with to their incomplete abortion,and which can be used as one of the valuable reference predictor of the success of the medical abortion for the miscarriage of the patients during the first trimester of pregnancy.
