title: [Infectious arteriopathies].
abstract: After reviewing the physiopathology, the authors report the principal features of infectious arterial disease observed in a department of infectious diseases. Excluding iatrogenic arteritis, particularly after vascular surgery, and some vasculitis in which an infectious agent may play a role, only the classical but now rare causes are described: rickettsial disease, syphilis and typhoid. The most commonly observed problem at present is infectious aneurysms: primary aneurysms secondary to atherosclerosis in which salmonella is by far the predominant organism, before the staphylococci and streptococci. The most serious complication is the major risk of rupture which may be the presenting event. Secondary aneurysms are essentially those of endocarditis. The mechanism is not fully understood and they occur at different stages of the course of the disease. The main problem associated with these aneurysms is their multiplicity and localisation; the intracranial forms are the most common and most serious in the experience of the authors, with their difficulties of diagnosis and treatment: extracranial aneurysms are usually located in the main limb arteries. Adjacent secondary aneurysms are exceptionally rare. Tuberculous and viral causes of aneurysm are among the rarest etiologies discussed.
