Chronic venous disease (CVD) affects about 0.5 to 3.0% of the population. The venous ulcer (UV) is the most advanced stage of CVD and affects the patient-age, worsening their quality of life and burdens the welfare system. Venous reflux is related to the genesis, development and maintenance of UV. To evaluate venous reflux in patients with UV. A cross-sectional study was performed, observational Vascular Surgery Service at the Federal University of Sergipe - Aracaju-SE, in a sample of 162 patients with active UV divided into two groups for evaluation of reflux: G1 (primary etiology) and G2 ( etiopathogenesis secondary) seen consecutively in the period of 03 / 2009-10 / 2010. Five patients were excluded because they had chronic ischemia, because they have two non-recanalized vein thrombosis and one for being pregnant. We investigated the age, gender, distribution of venous reflux in the superficial venous system (SVS), the deep venous system (DVS) and perforating veins (PVs), location of reflux in the SVS, types of reflux in the saphenous vein (GSV ) and saphenous vein (VSP) and distribution of reflux in the DVS. Statistical method: the database and statistical analysis were performed using the SPSS 18.0. Quantitative variables were summarized as mean and standard deviation. Categorical variables were described by simple frequency and percentages with their respective confidence intervals for 95%. The mean age was 53.7 years with a predominance of women (79%). The distribution of reflux was observed that all patients in G1 had reflux in the SVS without reflux in the DVS, VPs with 92% in G2 and 83.3% had reflux in the SVS, with 100% DVS and 92.3% in the VPs. Regarding the location of reflux in the SVS group G1 showed reflux in 96% in GSV and 14% VSP and G2 showed reflux in GSV 70% and 13% in VSP. Considering the types of saphenous vein reflux in G1 90% of the type I had reflux in the GSV and 71.5% type IV in VSP in G2 while 84% of reflux in the GSV type I and type IV 85.7% in VSP. In Group G2 approximately 70% of patients had reflux in these veins of the legs and 54% in the popliteal veins. The superficial system reflux was present in all patients with primary venous insufficiency and in most patients with secondary failure. The finding most often found in the superficial venous system was the GSV reflux. The reflux in the GSV type I and type IV reflux in VSP findings were more often found in the superficial venous system of patients in both groups. Approximately 70% of deep venous reflux was located in the leg, the popliteal vein being the most frequently affected.
