Enfoque del paciente con fenómeno de Raynaud / Approach to patients with Raynaud's phenomenon

Raynaud's phenomenon is a common disorder with vasospasm of the digital arteries causing pallor with cyanosis and/or rubor. It can be primary (idiopathic), where it is not associated with other diseases, or secondary to several diseases or conditions, including connective tissue diseases, such as scleroderma and systemic lupus erythematosus. Capillaroscopy is the most reliable way to distinguish between primary and secondary Raynaud's phenomenon through identification of an early pattern of systemic sclerosis. Treatment is often non-pharmacological, including avoiding cold and smoking cessation. Calcium channel antagonists are often considered when treatment is needed.
