Raynaud's syndrome. Coloured X-ray of the lower legs of a patient suffering from Raynaud's syndrome (symmetric asphyxia). One manifestation of the syndrome is the calcification of the arteries (blue spots). This disorder, of unknown origin, primarily affects the elderly. It is characterised by vasospastic attacks that cause the arteries in the digits to constrict, which interrupts the blood flow to these parts. The attacks often occur in response to cold. Treatment includes keeping the hands and feet warm, stopping smoking, and vasodilator drugs. Severe cases may require an operation to cut the nerve that makes the arteries spasm.
