    Abstract:
    Raynaud's phenomenon is a frequent reason for seeking of medical attention, since it affects 3-5% of the population. It is characterized by sudden, transient and recurrent episodes of pallor and/or digital cyanosis, after exposure to cold or stressful situations. No known underlying illness is identified in over 80% of cases and consequently these cases are classified as primary Raynaud's phenomenon. Connective tissue diseases, particularly systemic sclerosis, are the main causes of the phenomenon. Once a complete clinical and physical evaluation rule out other causes, a nailfold capillaroscopy and antinuclear antibodies determination are the most useful adjunctive tests. Mild Raynaud's phenomenon can be managed almost exclusively with conservative non-pharmacological lifestyle modifications. However, if a patient develops a severe vascular condition a suitable vasodilator treatment is needed. When critical digital ischemia develops, intravenous treatment with prostaglandin analogues and surgery may be useful.
