[Differential diagnostic problems in secondary acral circulatory disorders].

The broadly subdivided symptomatology of disturbances of the secondary acral blood supply, in which Raynaud's syndrome with its variants occupies a preferred position, demands solid basic knowledge of the physician, since triggering function or supporting permanent disturbance belong to a great number of basic diseases or primary disturbing factors. Thus the practicing physician has to do with comprehensive differential-diagnostic considerations with the aim of the correct recognition of the primary basic disease or noxa for the purpose of consequent induction of therapy. Angiological basis examinations, simple functional tests, a fundamental general physical examination, X-ray pictures granted for necessary and ECG-records as well as chemical laboratory findings alleviate the finding of the diagnosis like an exactly got anamnesis. In this therapeutic management subspecialists have then certainly only for a smaller part the task of further diagnostic clarification and therapeutic advice.
