Raynaud's phenomenon and peripheral ischemic syndromes

Abstract

Raynaud´s syndrome is an episodic disorder caused by vasospasm of peripheral arterioles. Exposure to cold temperatures or emotional stress is the most common underlying cause.

The clinical manifestation include a sudden change in the colour of the fingres (less often of the toes), edema, paresthesia, and during a severe course of the disease, atrophy may occur in the involved tissues with ulcers or gangrene.
