Horton's aortitis

Abstract

Giant cell arteritis is the most common systemic vasculitis in people over the age of 50 years. Ischaemic manifestations are well known. 'Occult' manifestations as aortic aneurysmal disease need consideration. The incidence of aortic aneurysm and/or dissection is about 18.5 per 1000 person-years at risk (18.9 in Lugo(4) and 18.7 in Olmsted County(3)). Predictive factors are hypertension, polymyalgia rheumatica, coronaropathy, and hyperlipaemia. Another factor is the apparition of an aortic regurgitation murmur as in this case. So, these patients should be monitored by echocardiography. © The Author 2008.
