Abstract Contexto: As alterações de pele manifestadas na insuficiência venosa crônica têm como etiologia mais comum o refluxo venoso. Alguns autores relatam que o refluxo venoso superficial é responsável por 40-60% das úlceras de perna nos portadores de varizes primárias. Objetivo: Correlação do refluxo venoso superficial ao mapeamento dúplex com o quadro clínico (classificação CEAP - clínica, epidemiológica, anatômica e fisiopatológica) nos portadores de varizes primárias de membros inferiores. Método: Estudo transversal e descritivo, desenvolvido em portadores de varizes primárias. As variáveis primárias foram: refluxo venoso e quadro clínico. O quadro clínico foi caracterizado por grupos: A, B e C, representados pelas categorias clínicas da CEAP. Dados complementares foram: tipos de refluxo em veias safenas magnas e parvas, conforme classificação de Engelhorn (2004). Testaram-se as hipóteses de inter-relações entre presença de refluxo e quadro clínico, utilizando-se os testes exato de Fisher e qui-quadrado no nível de 5% de probabilidade. Resultados: Das 242 extremidades inferiores examinadas, 15 foram excluídas, totalizando 227 na amostra final. Noventa e nove (83,9%) pacientes eram do sexo feminino. A média de idade foi de 50 anos, com mediana igual a 49 anos. Noventa e três extremidades (41%) não apresentavam refluxo, e 134 (59%) o apresentavam isolado e/ou associado. O refluxo isolado em veias perfurantes (p = 0,0008) e destas em associação com o refluxo em veias safenas magnas (p < 0,0001) estão significativamente relacionados à gravidade do quadro clínico. Conclusão: Há correlação entre a presença do refluxo venoso superficial ao mapeamento dúplex e a gravidade do quadro clínico nos portadores de varizes primárias de membros inferiores.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.
