大动脉炎（TAK）为累及主动脉及其主要分支的慢性进展性、非特异性大血管炎。我国为TAK高发地区，但其规范化诊疗的普及尚显不足。中华医学会风湿病学分会组织专家，在借鉴国内外诊治经验和指南的基础上，制定了本规范，旨在规范TAK的诊断、疾病活动度和疾病严重度的评估、内科治疗的合理制定及外科干预的时机选择，以保护TAK患者重要脏器功能，改善患者预后。“,”Takayasu′s arteritis (TAK) mainly involves the aorta and its major branches, which is characterized as a chronic, progressive and inflammatory disease. China belongs to one of the regions with a high prevalence of TAK referring to its global distribution. However, it is insufficient for the spread and update of standardized diagnosis and treatment of TAK. Based on the evidence and guidelines from China and other countries, Chinese Rheumatology Association developed the standardized diagnosis and treatment of TAK in China. The purpose is to standardize the methods for diagnosis of TAK, assessment of disease activity and disease severity, strategies of internal treatment and timing of surgical intervention, and further leading to protect the function of important organs and improve the disease prognosis.
