Abstract
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.

Resumen
Fundamento y objetivo

La arteritis de células gigantes (ACG) es la vasculitis sistémica más frecuente en adultos. En los últimos años, existe un interés creciente en evaluar la utilidad de la ecografía de arterias temporales superficiales (EATS), que permite valorar la inflamación de la pared vascular.

Material y métodos

Estudio de cohorte observacional y descriptivo de 120 EATS a 60 pacientes con sospecha clínica de ACG según criterios clásicos de ACR (American College of Rheumatology).

Resultados

De todos los pacientes a quienes se les realizó la EATS, el 42,3% presentó diagnóstico de ACG según los criterios de clasificación ACR. La sensibilidad y la especificidad de la ecografía en nuestra cohorte de pacientes con alta sospecha clínica fueron de 81,8 y 93,3%, respectivamente, con un VPP de 90,1% y un VPN de 87,5%.

Conclusión

Los resultados avalan la ecografía de arteria temporal bilateral como una técnica útil, indolora, rápida, accesible, de alta especificidad y amplia validez diagnóstica.
