PY - 2021 T2 - Venous Insufficiency AB - Symptoms from venous insufficiency are the result of distention of the veins and accumulation of fluid within the surrounding tissue. They include swelling and various forms of discomfort of the legs. In the later stages of the condition, damage to the skin results in discoloration and the formation of ulcers. This syndrome in varying stages of severity is common in the predominantly upright activities of humans. Epidemiology studies tell us of the high prevalence of the condition worldwide, most especially in the Western countries [1]. Yet numerous scientific articles on the subject begin with the statement that those cases of venous insufficiency are largely underdiagnosed and undertreated. Treatment to prevent progression of the disease is often long delayed because of overlooking the cause of early symptoms [2].
