title: [Anatomopathological aspects of arterial angiodysplasias].
abstract: Arterial angiodysplasias constitute an ill-defined entity comprising conditions of apparently very variable natures. Apart from arterial fibrodysplasia, the clinical features of which, if not the etiology, are well established, there exists a number of different arterial abnormalities, stenotic or aneurysmal, the significance of which remains unclear (dolicho-arteries, the Moya-Moya syndrome, etc.). However, the role of genetic factors and metabolic abnormalities in these conditions is uncontestable. They demonstrate both the authenticity of this group of diseases and the importance of metabolic disorders of the interstitial tissues in the majority of these vascular abnormalities.
