[Clinical aspects and differential diagnosis of primary acral circulatory disorders].

The disturbances of the primary acral blood supply show fluent transitions from the angiopathic position of the reaction over the digitus mortuus to Raynaud's disease. The functional vascular disturbances at stage II of Raynaud's disease change even to an organic arterial process. The various clinical pictures of the angioneuropathies can be differentiated in every ambulatory surgery in the majority of cases with the help of an aimed anamnesis on the basis of the clinical findings and by simple functional tests. When there are facts unclear, various apparative methods of diagnostics or the acral arteriography must be used.
