摘要: 探讨磁共振成像(MRI)定量参数、血β-人绒毛膜促性腺激素(β-HCG)与瘢痕妊娠清宫术后再治疗关系及临床意义。选取303例行B超引导下清宫术治疗的剖宫产瘢痕妊娠患者进行回顾性研究,根据术后是否再次入院治疗分为再治疗组、未再治疗组。比较两组瘢痕厚度、胚胎大小、血β-HCG,采用Logistic回归方程、受试者操作特征(ROC)曲线及ROC曲线下面积(AUC)处理分析数据。结果显示,再治疗组瘢痕厚度低于未再治疗组,胚胎大小、血β-HCG高于未再治疗组(P<0.05);瘢痕厚度、胚胎大小、血β-HCG均与再治疗独立相关(P<0.05)。瘢痕厚度、胚胎大小、血β-HCG预测再治疗的AUC值分别为0.734、0.811、0.819,三者联合的AUC值为0.902。因此,联合检测瘢痕厚度、胚胎大小、血β-HCG可预测剖宫产瘢痕妊娠B超引导下清宫术后再治疗的概率。

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.
