Acrocyanosis - Definition

Ask a question


Acrocyanosis is a vasomotor problem (relating to the modifications of the diameter of the blood vessels) that affects the extremities. Blood circulation is slows as a reaction to the contraction of the small vessels in the fingers and toes, which then become cold and tinged with blue, sometimes swollen. Affecting especially young people, this peripheral vascular disease is not dangerous and generally improves with age. It's a mostly seasonal problem aggravated by the cold or humidity. Protection of the extremities against low temperatures is the best treatment. It can sometimes be confused with Raynaud's disease.
