Clinical Applicability of Ultrasound in Systemic Large Vessel Vasculitides.

The systemic large vessel vasculitides consist mainly of giant cell arteritis and Takayasu arteritis. Both diseases affect the large blood vessels and can lead to ischemia and end-organ damage. Ultrasound is an imaging technique that can depict inflammation of the vessel wall in large and medium vessel vasculitis. In this article, we critically review the current evidence for the clinical use of ultrasound for systemic large vessel vasculitides, regarding the clinical applicability, technical requirements, challenges, and cost. A roadmap for the development of a fast-track ultrasound clinic for giant cell arteritis is also provided.
