Abstract

Vasculitides, including Wegener's granulomatosis, Takayasu's arteritis, giant cell arteritis, Kawasaki disease, Behçet disease, thromboangiitis obliterans and erythema elevatum diutinum, are inflammatory diseases of blood vessel wall characterized by myointimal proliferation, fibrosis and thrombus formation leading to stenosis or occlusion of the vascular lumen, and finally to tissue ischemia. In these diseases the hypoxic environment subsequent to stenosis or occlusion of the vascular lumen is a potent signal for the generation of new blood vessels. Angiogenesis may be a compensatory response to ischemia and to the increased metabolic activity and may be also a further inflammatory stimulus because endothelial cells of newly-formed vessels express adhesion molecules and produce colony-stimulating factors and chemokines for leukocytes.
