[Horton's disease with bilateral axillohumeral localization. Arteriographic aspects. 2 cases].

These lesions, which may present with ischaemic symptoms or which may be detected by routine examination of the pulse and blood pressure, need to be recognised, as they may lead to the diagnosis of Horton's disease which requires corticosteroid treatment. Subclavian angiography demonstrates bilateral segmental lesions with areas of thrombosis. The histology confirms the arteritis. Corticosteroid treatment caused the ischaemic signs to disappear and the pulse to return.
