Veins carry deoxygenated blood. Varicose veins are knobby, twisted and darkish-blue in appearance, and are most commonly found on the legs. Blood is collected in the superficial veins of the leg, just below the skin surface, and delivered to deeper veins that run within the calf muscles. The muscular action of the calves helps to pump the blood against the force of gravity towards the heart. One-way valves inside the veins prevent blood from travelling backwards. If these valves fail to close properly, blood pools in the superficial veins. Over time, the affected veins swell with blood (become 'varicose'). The cause is unknown. Varicose vein surgery is the removal of these distended veins. Treatment can be undergone for therapeutic or cosmetic reasons.Varicose veins usually affect the legs, particularly the calf and sometimes the thigh. They are caused by damage to valves in the veins. This means that blood can't travel up your veins as easily as it should and tends to pool in the leg. Varicose veins are very general and slightly more common in women than men. Surgery is often the best option for varicose veins visible below the skin. It is generally most successful in the main varicose veins which will be entirely removed. Surgery will not help thread or spider veins which are found within the layers of the skin itself and cannot be physically removed. Smaller reticular veins are also best treated by sclerotherapy.The operation is generally carried out under a general anesthetic and you are asleep and unaware throughout the process. The commonest operation (high tie or saphenofemoral ligation) is where a cut is made in the groin over the top of the main varicose vein. This is then detached where it meets the deeper veins (femoral vein). A main varicose vein (greater saphenous vein) on the inner part of the leg is then exposed out.Varicose veins don't always require treatment as not everyone will get symptoms. However, your varicose veins won't get improved without treatment, and they tend to get worse over time. Varicose vein surgery has been shown to be clinically effective
