Arteritis

Arteritis is a vascular disorder characterized by inflammation of the walls of arteries, usually as a result of infection or autoimmune responses. Arteritis, a complex disorder, is still not entirely understood. Arteritis may be distinguished by its different types, based on the organ systems affected by the disease. A complication of arteritis is thrombosis, which can be fatal. Arteritis and phlebitis are forms of vasculitis.
