[Vascular "remodeling"].

Vascular remodeling means a specific organization of the vascular wall around a diminished lumen as to the before existing conditions, with consequent vascular geometry modification. This organization comes from the response of all vascular components (endothelium, muscular cells, connective component, etc.) to physical and chemical stimuli. Particular behaviour of the vascular wall has lately been pointed out, both in long known pathologies (arteriosclerosis, arterial hypertension, diabetes mellitus, arteriosclerotic aneurysms) and in situations involving both physiopathology (ischaemia-reperfusion, angiogenesis) as therapy (angioplasty).
