Chronic venous disease (CVD) is a widespread and challenging condition globally, encompassing the full range of anatomical and functional abnormalities in the venous system of the lower extremities. It is characterized by symptoms such as edema, skin changes, and venous ulcers, primarily caused by venous insufficiency with resulting reflux. CVD significantly impacts quality of life and imposes a considerable socioeconomic burden. Lifestyle factors play a critical role in the risk of developing CVD. In recent years, average body mass index (BMI) values have risen in Western countries, with obesity recognized as a major risk factor for CVD. Additional factors, including smoking, physical inactivity, and hypertension, are also linked to an increased risk of CVD and chronic venous insufficiency. There is a lack of recent Brazilian data on the prevalence and epidemiological characteristics of CVD, highlighting the need for this study. This research aims to gather national data on risk factors, associated comorbidities, and treatment types in Brazilian patients with CVD. The primary goal is to describe the clinical and epidemiological profile of CVD in the Brazilian population.
