[Functional peripheral ischemia].

The terminal circulation which plays an important role in the thermoregulation particularly at the periphery of the extremities is not infrequently irritated by false multifactorial regulations. As their sequela an increased tonus of vasoconstrictors and pathological vasodilatation lead to idiopathic and symptomatic functional angiolopathies. Transitions into organic vascular processes are no rarity. From the extreme functional behaviour patterns complaints and symptoms of the individual angiolopathies may be derived. Clinic, differential diagnostics and therapeutic possibilities of the angiopathic reaction position, of the acrocyanosis and its variants, of the intermittent functional acrosyndromes and of the erythromelalgia are treated from practical points of view. In contrast to the secondary functional angiolopathies, in which the basic disease is of decisive importance in questions concerning expertise, the idiopathic forms alone are scarcely of high significance concerning the restriction of the physical function.
