Diseases of Vasoconstriction

Abstract

Vasoconstriction of some degree is almost always present in the skin of the extremities; it is more active in peripheral sites. Vasoconstriction may be caused by stimuli of central origin or by reflexive responses to peripheral stimuli. Cold and posture are the most significant causes of reflexive stimuli. Abnormal vasoconstriction is seen in Raynaud's disease, post-traumatic dystrophy, certain occlusive diseases associated with inflammation, and Buerger's disease. Treatment consists of appropriate hygienic measures, drug therapy and sympathectomy, as indicated.
