What Is Venous Disease?
Venous disease refers to all of the conditions caused by veins that become diseased or abnormal. Venous disease is quite common with up to 25 per cent of the adult population being affected. Mild venous disease is not normally a problem but if the venous disease worsens, it can become chronic leading to chronic venous insufficiency.
Within your body, arteries carry blood which is rich in oxygen from your heart to the body, and veins return the blood back to your heart. Veins have valves along with them which keep the blood flowing back up to the heart. As muscles in your body contract, blood is squeezed forward in the veins returning to the heart. The valves then shut to prevent blood from flowing backwards when the muscle relaxes.
There are three types of veins in your legs, superficial veins, perforator veins and deep veins. Superficial veins are the veins that only carry a small amount of blood in your legs (about 10-15%). Your deep veins do most of the work and carry up to 90% of the blood back to your heart.
If the valves in your veins become diseased or damaged, when your muscles relax, the blood starts to pool back in your veins causing them to bulge and twist. This swelling of the veins with abnormal flow creates disorders known as venous disease. Removing these veins does not affect the passage of blood going back to your heart as the deep veins perform most of the work.
Venous disease can include some of the following:
