Acrocyanosis is a disorder that affects the arteries supplying blood to the skin of the hands and feet. Spasm of the arteries can occur, blocking the flow of blood.
These small arteries carry oxygen and nutrients through the blood to the skin of the hands and feet. When the blood cannot flow through, the skin will lack the necessary oxygen required, and turn a dark blue to purple color. This characteristic color is called cyanosis.
Acrocyanosis is seen more frequently in woman than in men. Symptoms include persistently cold temperature and blue discoloration, sweaty or moist skin, and swelling.
Treatment includes insulated boots, thin polypropylene liner socks to wick the moisture away from the skin, and an insulated sock to maintain normal skin temperature.
