[Etiologic diversity of digital arteritis].

The etiological study of a series of 30 cases of digital arteritis, shows that there may be various causes at the origin of a digital arteritis. In elderly patients, atherosclerosis appears as the most frequent cause. At a middle age, digital arteritis frequently occurs in a context of vasomotor pathology: in this case, sclerodermis is a frequent cause to examine systematically but some cases are secondary to a Raynaud's phenomenon, apparently idiopathic. Other etiologies: traumatic, hematologic, iatrogenic... may be pointed out; but in some cases, digital arteritis occurs alone without any apparent reason.
