Raynaud's phenomenon is a common clinical problem occurring in 3% to 5% of the general population. The first symptom of scleroderma is often Raynaud's phenomenon, which is associated with a diffuse small vessel vasculopathy, and ischemia and reperfusion injury to skin and other organs targeted in this disease. Current studies support the concept that Raynaud's phenomenon is secondary to a local defect in the regulation of regional blood flow. New evidence demonstrates that there is a profound sensitivity to α2-adrenoceptors mediated vasoconstriction in scleroderma vessels. Traditional treatment of Raynaud's phenomenon is cold avoidance and the use of vasodilators. Oral prostaglandins have shown promise as therapeutic agents.
