The cause of the inflammation is unknown. It is likely related to autoimmune factors. The wall of the blood vessel may scar and thicken, or die (become necrotic). The blood vessel may close, interrupting blood flow to the tissues it supplies. The lack of blood flow will cause the tissues to die.
Necrotizing vasculitis may affect any blood vessel in the body. Therefore, it can cause problems with the skin or any of the body's organs.
Fever, chills, fatigue, or weight loss may be the only symptoms at first. However, symptoms may be in almost any part of the body.
Call your health care provider if you have symptoms of necrotizing vasculitis.
Emergency symptoms include:
Changes in pupil size
Loss of function of an arm, leg, or other body part
There is no known way to prevent this disorder.
