Varicose veins are caused by a defect in the valves directing one way flow inside the veins. When the valves are not functioning correctly, the blood backs up into the surface (superficial) veins and presents as varicosities. The reason that it is more likely to occur in the legs is that there is a greater fluid pressure caused by gravity's effect on the column of blood within your body.
Varicose veins can develop in the deep veins also. Varicose veins in the superficial veins are called primary varicosities, while varicose veins in the deep veins are called secondary varicosities.

The superficial veins are the blood vessels most often affected by varicose veins and are the veins seen by eye when the varicose condition has developed.
The scientific name for veins that are close to the surface is superficial veins. These are the veins you can see under your skin.
Varicose veins are veins that are swollen and sometimes painful. They may also be twisted and can have more blood in them then normal.
Venous insufficiency is a condition in which blood pools in the vein because the valves have become incompetent.
