That is called Vericose Veins. They happen when the return of blood to the heart valves fail to close properly forming pools of blood in the vein and over time will force the vein ******d resulting in enlarged and sometimes bulging giving it a rope appearance. This condition is hereditary and is also aggrivated by pregnancy, menopause, obesity, aging of tissues and use of birth control and hormonal therapy.
There are two alternatives to treatment of Vericose Veins;
One: Since valves cannot be repaired, they re-route the blood flow through healthy veins. they do this by removing (or stripping) the vein from your leg.
Two: This is a less invasive treatment that can be done as day surgery. They give you local anesthesia then put a thin catheter that delivers radiofrequency energy to the vein wall, causing it to heat, collapse and shut down. Once the diseased vein is closed, other healthy veins take over and empty blood from your legs.
After they remove the catheter they put a bandage over the site of insertion and the leg is wrapped for a few days. Sometimes the doctor will ask you to wear stockings that are tight (these are special stockings) to hold the pressure. You may also be asked to stay off your feet for a few days.
Some insurance companies will cover this procedure if it is found to be medically necessary and not just cosmetic. Check with them first.
Hope this was of some help to you!
