[Minimal work-up for Raynaud syndrome: a consensus report. Microcirculation working group of the Société française de médecine vasculaire].

About ten to fifteen percent of the French population suffer from Raynaud's phenomenon. Most of the time, it is considered as primary Raynaud's phenomenon, without underlying disease. The aim of this expert consensus from the "microcirculation group" for the French Society of Vascular Medicine and the French Society for Microcirculation, was to define clinical guidelines in patients consulting for Raynaud's phenomenon. The recommended minimal screening includes clinical examination, nailfold capillaroscopy and antinuclear antibodies. In particular, the aim of this screening is to identify patients with a significant risk for scleroderma, who would need a careful follow up.
