[Clinical aspects of the progression of nonspecific brachiocephalic aortoarteritis].

Based on the features of the clinical course of nonspecific aorto-arteritis, three types of the course were identified: slowly progressive, rapidly progressive, and recurrent. The progression of the disease and involvement of new arterial beds into the pathological process were found to primarily depend on persistent inflammation. It is suggested that the types of the clinical disease course are directly related to immunological responsiveness.
