Resumo
Contexto: A insuficiência venosa crônica (IVCr) é frequente e predomina nas mulheres, mas ainda há poucas informações sobre o refluxo nas veias safenas na população masculina. Objetivos: Identificar os diferentes padrões de refluxo nas veias safenas magnas (VSMs) e parvas (VSPs) em homens, correlacionando esses dados com a apresentação clínica conforme a classificação Clínica, Etiológica, Anatômica e Fisiopatológica (CEAP). Métodos: Foram avaliados 369 membros inferiores de 207 homens pela ultrassonografia vascular (UV) com diagnóstico clínico de IVCr primária. As variáveis analisadas foram a classificação CEAP, o padrão de refluxo nas VSMs e VSPs e a correlação entre os dois. Resultados: Nos 369 membros avaliados, 72,9% das VSMs apresentaram refluxo com predominância do padrão segmentar (33,8%). Nas VSPs, 16% dos membros inferiores analisados apresentaram refluxo, sendo o mais frequente o padrão distal (33,9%). Dos membros classificados como C4, C5 e C6, 100% apresentaram refluxo na VSM com predominância do refluxo proximal (25,64%), e 38,46% apresentaram refluxo na VSP com equivalência entre os padrões distal e proximal (33,3%). Refluxo na junção safeno-femoral (JSF) foi detectado em 7,1% dos membros nas classes C0 e C1, 35,6% nas classes C2 e C3, e 64,1% nas classes C4 a C6. Conclusões: O padrão de refluxo segmentar é predominante na VSM, e o padrão de refluxo distal é predominante na VSP. A ocorrência de refluxo na JSF é maior em pacientes com IVCr mais avançada.

Abstract
Background: Chronic venous insufficiency (CVI) is frequent and predominantly affects women, but there is a lack of information about saphenous vein reflux in the male population. Objective: To identify different patterns of reflux in the great and small saphenous veins of men and correlate them with clinical presentation graded according to the Clinical-Etiology-Anatomy-Pathophysiology (CEAP) classification. Methods: A total of 369 lower limbs in 207 men with a clinical diagnosis of primary CVI of the lower limbs were evaluated using vascular ultrasound (VU). The variables analyzed were CEAP clinical classification, patterns of reflux in the great and small saphenous veins, and the correlations between them. Results: A total of 369 limbs were evaluated and in 72.9% of them the great saphenous vein (GSV) had reflux, predominantly the segmental pattern (33.8%), while in 16% of the lower limbs analyzed the small saphenous vein (SSV) had reflux, among which the most frequent pattern was distal (33.9%). All limbs classified as C4, C5, or C6 had GSV reflux, predominantly proximal (25.64%), while 38.46% had SSV reflux compatible with distal and proximal reflux patterns (33.3%). Reflux was detected at the saphenofemoral junction (SFJ) in 7.1% of limbs graded C0 and C1, in 35.6% of C2 and C3 limbs and in 64.1% of C4 to C6 limbs. Conclusion: The predominant reflux patterns are segmental at the GSV and distal at the SSV. The frequency of SFJ reflux is higher in patients with more advanced CVI.
