Objectives: to describe videocapillaroscopy (VCP) findings in patients with primary Raynaud's phenomenon (PRP) and secondary (SRP); compare demographic and clinical characteristics between both.Materials and methods: observational, analytical, cross-sectional study. Age, occupation, evolution time of RP, connective tissue disease (CTD) and capillaroscopic characteristics were documented. The VCP were reported as normal, nonspecific or early, active, and late SD pattern. Descriptive statistics were performed. Chi2 or Fisher's exact test were used for categorical variables; for continuous variables t test or Man Whitney, considering statistically significant p<0.05.Results: 290 VCP were performed. In patients with PRP (n:122), 18% (n:23) were normal and 81% (n:99) non-specific. In patients with SRP (n:168), 8% were normal, 42% non-specific and 51% with SD pattern (25% early, 44% active, 31% late). We found statistically significant differences: time of evolution of RP in months (12 vs. 36, p<0.01), normal VCP (18.85% vs 7.4%, p<0.01), non-specific pattern (81.14% vs 41%, p<0.01) in patients with PRP vs SRP.Conclusions: in patients with FRS predominated the SD pattern, while in those with FRP the normal and nonspecific pattern was superior. FRS was associated with a longer evolution time.
