Varicose veins.

Varicose veins are called dialated veins

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.

Venous insufficiency is a condition in which blood pools in the vein because the valves have become incompetent.

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.
