In 1862, Maurice Raynaud recognized that some people who were exposed to cold temperatures had transient digital ischemia that he ascribed to an exaggerated response of the central nervous system. The term "Raynaud's phenomenon" is now used to describe these episodic events, which represent vasoconstriction of the digital arteries, precapillary arterioles, and cutaneous arteriovenous shunts.
