BACKGROUND AND OBJECTIVE
Giant cell arteritis (GCA) is the most frequent systemic vasculitis in adults. In recent years, the usefulness of temporal artery ultrasound (TAUS) as a diagnostic tool to assess the underlying inflammation of the vascular wall during the inflammatory process has been under clinical investigation.
MATERIAL AND METHODS
Observational and descriptive cohort study of 120 TAUS in 60 patients with clinical suspicions of GCA, according to the ACR (American College of Rheumatology) classification criteria.
RESULTS
Among all patients who underwent ultrasound, 42.3% met clinical criteria for GCA according to ACR. Sensitivity and specificity of TAUS in our cohort with clinical suspicion was 81.8% and 93.3%, respectively. A PPV of 90.1% and a VPN of 87.5% were observed.
CONCLUSION
Our results showed that TAUS as a useful, indolent, fast, and accessible tool with high diagnostic specificity and diagnostic value.
背景与目的
巨细胞动脉炎（GCA）是成年人中最常见的系统性血管炎。近年来，颞动脉超声（TAUS）作为一种诊断工具，用于评估炎症过程中血管壁的潜在炎症，已在临床研究中得到广泛关注。
材料与方法
对 60 例临床疑似 GCA 患者的 120 次 TAUS 进行观察性和描述性队列研究，这些患者均符合 ACR（美国风湿病学会）分类标准。
结果
在所有接受超声检查的患者中，根据 ACR，42.3%的患者符合 GCA 的临床标准。在我们具有临床可疑症状的患者队列中，TAUS 的敏感性和特异性分别为 81.8%和 93.3%。观察到阳性预测值为 90.1%，阴性预测值为 87.5%。
结论
我们的结果表明，TAUS 是一种有用、惰性、快速且易于获得的工具，具有较高的诊断特异性和诊断价值。
