Polyarteritis nodosa is a serious blood vessel disease in which small and medium-sized arteries become swollen and damaged.
Causes, incidence, and risk factors
Polyarteritis nodosa is a disease that affects arteries, the blood vessels that carry oxygen-rich blood to organs and tissues. The cause is unknown, but it occurs when certain immune cells attack the affected arteries.
More adults than children get this disease. The tissues that are fed by the affected arteries do not get the oxygen and nourishment they need, and become damaged.
People with active hepatitis B and C may develop this disease.
Symptoms are caused by damage to affected organs, often the skin, heart, kidneys, and nervous system.
Call your health care provider if you develop symptoms of this disorder. Early diagnosis and treatment may improve the chance of a good outcome.
There is no known prevention. However, early treatment can prevent some damage and symptoms.
