摘要
目的 分析CTA与DSA在评估慢性肢体威胁性缺血(CLTI)患者全球肢体解剖学分期系统(GLASS)分期中的一致性.方法 回顾性分析2017年1月至2020年12月西安交通大学第一附属医院收治的CLTI患者临床资料.以DSA评估结果为金标准,分析CTA与DSA评估GLASS分期的一致性.结果 CTA评估GLASS评分与DSA具很强的一致性,其中两者评估股胭动脉段评分的加权Kappa系数为 0.798(95％ CI=0.722～0.873,P＜0.01),评估膝下动脉段评分的加权 Kappa 系数为 0.785(95％ CI=0.725～0.845,P＜0.01),评估 GLASS 整体评分的加权 Kappa 系数为 0.832(95％CI=0.752～0.911,P＜0.01),均显示出很强的一致性.结论 下肢动脉CTA检查可准确评估CLTI患者靶病变GLASS评分和分期,有助于下肢动脉硬化闭塞症诊断及血运重建技术难度评估.
Abstract
Objective To analyze the consistency between computer tomography angiography(CTA)and digital subtraction angiography(DSA)in evaluating the global limb anatomic staging system(GLASS)stage of patients with chronic limb-threatening ischemia(CLTI).Methods The clinical data of patients with CLTI,who were admitted to the First Affiliated Hospital of Xi'an Jiaotong University of China to receive treatment between January 2017 and December 2020,were retrospectively analyzed.Taking the DSA assessment as the gold standard,the consistency of CTA and DSA in evaluating the GLASS stage of patients with CLTI was analyzed.Results In the assessment of GLASS stage of CLTI,CTA showed strong agreement with DSA.The weighted Kappa coefficient of CTA and DSA for the staging of femoropopliteal segment was 0.798(95％CI=0.722-0.873,P＜0.01),and the weighted Kappa coefficient of CTA and DSA for the staging of infrapopliteal artery segment was 0.785(95％ CI=0.725-0.845,P＜0.0l).For the overall staging of GLASS,the weighted Kappa coefficient of CTA and DSA was 0.832(95％ CI=0.752-0.91 1,P＜0.01).All the above results indicated that a very strong consistency existed between CTA and DSA in evaluating the GLASS stage of patients with CLTI.Conclusion CTA examination of lower limb can accurately evaluate GLASS score and stage of CLTI patient's target lesions,which is helpful in diagnosing lower extremity arteriosclerosis occlusion disease as well as in assessing the technical difficulty degree of its revascularization operation.(J Intervent Radiol,2024,33:300-303)
