Giant cell (temporal) arteritis: what GPs need to know
Giant cell arteritis (GCA), also known as temporal arteritis, is a chronic medium to large vessel vasculitis that occurs in people over the age of 50 years. It commonly involves the cranial arteries, and may cause acute irreversible visual loss. Prompt recognition of the key clinical and laboratory features allows early initiation of corticosteroid therapy with the aim of preventing blindness and other complications. Longer term monitoring and treatment focuses on preventing relapse and minimising harms from prolonged corticosteroid use.
