[Involvement of large arteries by Horton's disease].
Up to 15% of patients with temporal arteritis, may have large vessel involvement. The ascending aorta, aortic arch, subclavian and axillary arteries are most frequently involved. These localisations may be the presenting feature but usually, temporal arteritis is known or symptomatic at the time of large vessel involvement discovering. When corticosteroids are given in adequate doses, the response is favorable in most patients with limbs localisation but aortic localisation is associated with a markedly increased risk for the development of aneurysm and dissection which may cause death.
