vasculitis

Full Definition

Vasculitis refers to a group of disorders characterized by inflammation of blood vessel walls, which can lead to vessel narrowing, occlusion, or rupture. The condition can affect vessels of any size and type, from large arteries to small capillaries, and may be primary (idiopathic) or secondary to other diseases. Clinical manifestations vary widely depending on the affected vessels and organs, making accurate diagnosis and classification essential for appropriate treatment.
