Vasculitis Disorders

Alternative Names: Vasculitis

Disease Category: Vasculitis Disorders

Vasculitis means inflammation of the blood vessels, arteries, veins or capillaries. When such inflammation occurs, it causes changes in the walls of blood vessels, such as weakening and narrowing that can progress to the point of blood vessel blockage. A result of vasculitis is that the tissues and organs supplied by affected blood vessels do not get enough blood.
