Varicose Vein Removal
Varicose veins are distended, visible superficial veins on the legs. Though any vein may become varicose, the veins most commonly affected are those in your legs and feet. That's because standing and walking upright increases the pressure in the veins of lower body.
Varicose veins almost always result in problems with valves within the venous system of the leg. All leg veins contain one-way flap valves which are designed to help the flow of blood in the veins in an upward direction on its return to the heart.
But, when one or more of these valves fails to function correctly, some blood is able to flow back down into the leg - in the wrong direction - and tends to overfill and distend branches of superficial veins under the skin. Over a period of time, this additional pressure of blood causes the veins to stretch, bulge and become visible. At the same time, tiny capillary branches of the veins are also overfilled with blood, producing multiple spider veins and purple discoloration.
Most of the varicose veins are caused by faulty valves in the groin or behind the knee. At both these sites there is a major junction at which superficial veins flow into the important deep veins of the leg, with a one-way valve to control flow at the junction.
Varicose vein removal surgery involves removing any superficial veins which have become varicose veins. There are many types of operation you can have, depending on which veins need treatment. The most common is called ligation and stripping.
The operation is usually done as a day case under general anesthesia. This means you will be asleep during the procedure.
Although many people won't need any further treatment after surgery, the ratio of 3 to 10 people can develop more varicose veins within the next 10 years.
