Outcome Measures
Primary Outcomes (4)
Incidence of Chronic Venous Disease
Number of Participants with the first identified signs of chronic venous disease according to CEAP classification (telangiectasia, varicose veins, edema)
1 year
Natural Course of Chronic Venous Disease
Progression of CVD will be measured as a change in clinical class of CVD according to CEAP classification in every individual affected by CVD
1 year
Incidence of chronic venous insufficiency
Number of Participants with the first identified sign of chronic venous insufficiency (venous edema, venous eczema, hyperpigmentation of the skin, lipodermatosclerosis, venous ulcer)
1 year
Incidence of superficial vein thrombosis
Number of Participants with the first identified sign of superficial vein thrombosis
1 year
Study Arms (2)
Patients without Chronic Venous Disease
Individuals who do not have signs of chronic venous diseases of lower legs according to Clinical, Etiologic, Anatomic and Pathophysiologic classification (CEAP)
Patients with Chronic Veinous Disease
Individuals who have signs of chronic venous diseases of lower legs according to CEAP classification (telangiectases, varicose veins, venous edema, skin hyperpigmentation, lipodermatosclerosis, venous ulcer).
Eligibility Criteria
The main cohort is formed from those who do not have CVD, who are affected by different factors that we register (various physical activities, the presence or absence of pregnancy, etc.). An additional cohort is formed from those who have CVD at the time of inclusion. The goal is to track the natural evolution (progression) of the disease, to evaluate the incidence and risk factors of complications. An extremely important criterion for the formation of the study population is the possibility to control the lower legs veins of observed individuals by a qualified vascular specialist. To date, a qualitative assessment of veins according to the CEAP classification is a weak point in longitudinal epidemiological studies.
You may qualify if:
- A family members of the researcher (spouse, childrens, brothers and sisters, parents) or the researcher himself
- The possibility of annual clinical and ultrasound assessment of the venous system of the observed individuals
You may not qualify if:
- Any invasive treatment of the chronic venous disorder in anamnesis
