URREGO-CALLEJAS, Tomás et al. Temporal artery Doppler ultrasound in patients with giant cell arteritis: State of the art and systematic review of the literature. []. , 28, 3, pp.203-212.   19--2022. ISSN 0121-8123.  https://doi.org/10.1016/j.rcreu.2020.08.003.

Giant cell arteritis is a vasculitis that predominantly affects large calibre vessels, and usually appears in people over 50 years-old. Its clinical presentation includes headache, hearing impairment, or polymyalgia rheumatica-like symptoms. In its most severe form, it can cause uni- or bilateral vision loss secondary to arteritic ischaemic optic neuropathy. Currently, the gold standard for its diagnosis is the temporal artery biopsy, a procedure that is not harmless and may have complications such as infection, nerve injury, bleeding, among others. Among non-invasive diagnostic methods, the ultrasound and temporal artery Doppler have gained a predominant role in the diagnosis of giant cell arteritis, as it is a benign test with no adverse effects. Through strategies such as «fast-track» clinics, supported by this diagnostic method, a reduction has been achieved in ischaemic complications of the disease.
