目的研究影响桡动脉-头静脉自体动静脉内瘘(RCAVF)成熟因素,联合显著相关因素预测成熟可能性。方法选择2017年7月至2019年12月在大连医科大学附属第二医院首次行RCAVF手术并成功患者257例,其中男性169例,女性88例;年龄24~90岁,平均年龄59.4岁;病程0.81~5.00年,平均病程3.53年;高血压217例(84.4%),糖尿病166例(64.6%)。术前行血管超声检查,记录患者基本信息(年龄、性别)、基础疾病(高血压、糖尿病及肾脏疾病)及血清学指标[尿素、肌酐、尿酸、胱抑素C及肾小球滤过率(e GFR)]。术后连续6个月随访RCAVF成熟情况,采用单因素Logistic回归及多因素Logistic回归分析影响RCAVF成熟因素,获取显著性相关因素,绘制受试者工作特性(ROC)曲线,获得曲线下面积(AUC)、最佳临界值、灵敏度及特异度。根据最佳临界值,将多因素差异有统计意义的指标采用联合方式,获得联合诊断效能。结果行左前臂造瘘者210例(81.7%),右前臂造瘘者47例。RCAVF术后均获得成功。随访6个月内达到临床成熟者为182例,未达到临床成熟者为75例。RCAVF未成熟组年龄、eGFR高于成熟组(年龄:P=0.036;eGFR:P=0.008),而RCAVF成熟组桡动脉近腕部管径及桡动脉近肘部管径、肌酐均高于未成熟组(桡动脉近腕部及近肘部管径均P<0.001;肌酐:P=0.002),差异均有显著统计学意义。单因素Logistic回归分析显示,年龄、桡动脉近腕部及近肘部管径、头静脉近肘部管径、肌酐、e GFR与RCAVF成熟显著相关(P<0.05);多因素Logistic回归分析结果显示,年龄、eGFR为RCAVF成熟阻碍因素,桡动脉近肘部管径为促进因素(P<0.05)。采取联合预测,获得最高AUC值为0.661,最高特异度可达94.29%,最高灵敏度可达96.00%。结论将桡动脉近肘部管径、年龄与eGFR三者联合预测RCAVF成熟,可获取较好的诊断效能、灵敏度及特异度,为评估患者是否适合采用RCAVF进行透析提供参考。
