Abstract

Abstract: This study explored the relationship and clinical significance of magnetic resonance imaging (MRI) quantitative parameters,blood β-human chorionic gonadotropin (β-HCG) and retreatment after uterine evacuation of scar pregnancy, and provide references for clinical diagnosis and treatment of diseases. A retrospective study was conducted on 303 cases of cesarean scar pregnancy patients who underwent B-ultrasound-guided evacuation treatment. They were divided into retreatment group and no retreatment group according to whether they were re-admitted to the hospital after operation. The scar thickness, embryo size, blood β-HCG were compared between the two groups, and the logistic regression equation, receiver operating characteristic curve (ROC) and area under ROC (AUC) were used to process and analyze the data. The results showed that the scar thickness of the retreatment group was lower than that of the no-retreatment group (P<0.05). The embryo size and blood β-HCG were higher than that of the no-retreatment group (P<0.05). The scar thickness, embryo size, and blood β-HCG were independently related to retreatment (P<0.05); Scar thickness, embryo size, and blood β-HCG predicted AUC values for retreatment were 0.734, 0.811, 0.819, respectively. The combined AUC value of the three was 0.902. Therefore, combined detection of scar thickness, embryo size, and blood β-HCG can predict the probability of retreatment after cesarean section scar pregnancy under the guidance of B-ultrasound.
