    Background: Skin changes observed in chronic venous insufficiency have venous reflux as the most common etiology. Some authors have reported that reflux in the superficial venous system accounts for 40-60% of leg ulcers in patients with primary varicose veins. Objective: To evaluate the correlation between superficial venous reflux and clinical status (CEAP classification - clinical, etiology, anatomy and pathophysiology) in patients with primary varicose veins of the lower limbs using duplex scanning. Method: A cross-sectional and descriptive study was performed in patients with primary varicose veins. Primary variables were venous reflux and clinical status. Clinical status was characterized by groups A, B, and C, represented by CEAP clinical categories. Types of venous reflux in the great and small saphenous veins were used as complementary data, according to Engelhorn’s classification (2004). Hypotheses of interrelationship between incidence and types of reflux were statistically analyzed using Fisher’s exact and chi-square tests. Significance was set at 0.05%. Results: Of 242 lower limbs, 15 were excluded, so that the final sample was comprised of 227 lower limbs. Ninety-nine (83.9%) patients were female. Mean age was 50 years and median was 49 years. Reflux was absent in 93 limbs (41%), and 134 (59%) showed isolated and/or associated reflux. Isolated reflux in perforating veins (p = 0.0008) or in association with great saphenous vein reflux (p < 0.0001) was significantly related to clinical status severity. Conclusion: Duplex scan showed correlation between presence of superficial venous reflux and clinical status severity in patients with primary varicose veins of the lower limbs.
