Acrosyndromes are abnormalities in the circulation of the hands or feet.
The best known acrosyndrome is Raynaud's phenomenon. It is a circulatory disorder of the extremities, characterized by a change in color of the skin which becomes white , then possibly a bluish coloration, associated with tingling and a sensation of dead fingers.
In 80% of cases, this acrosyndrome is not related to an underlying pathology.
During the consultation, the doctor will look for associated signs such as joint pain, difficulty swallowing, shortness of breath, thickening of the skin on the hands or finger wounds that are difficult to heal.
The explorations include a periungual capillaroscopy and a blood test to rule out secondary causes. Eventually, an arterial echo-doppler and a digital pressure measurement can be added.
