Patient Information — Venous Anatomy
Like arteries, veins are blood vessels. Arteries pump blood from the heart carrying oxygen to every area of the body. Veins then return the blood to the heart.
To move the blood back to the heart, veins rely on a system of muscular pumps and valves. Healthy veins allow blood to move in only one direction, toward the heart.
Chronic Venous Insufficiency
When veins become incompetent or insufficient, some of the blood flows backward or refluxes and collects in veins that become swollen as a result.
A range of health problems can result, including the formation of varicose veins, spider veins, reticular veins and edema. These conditions may create cosmetic concerns but they are progressive and can develop into serious medical issues, including skin changes and ulceration.
