What is venous insufficiency?
Venous insufficiency occurs when the normal flow of blood from the superficial veins to the heart via the perforating deep veins in the lower limbs is impaired, resulting in chronic venous congestion. It can be classified as superficial vein insufficiency, perforating, or deep vein insufficiency.

Who gets venous insufficiency?
Venous insufficiency is common, affecting all races and both sexes. Estimates suggest rates as high as 50% in some populations. A US study found ethnic whites had a higher rate of venous insufficiency compared to Hispanics, African Americans, and Asians. The Edinburgh Vein Study reported the incidence of chronic venous insufficiency was similar in men and women. Prevalence increases with age, obesity, a family history of varicose veins, and multiple pregnancies.
