A laser is a highly focused beam of light. A doctor can use a laser to treat varicose veins. Laser heat damages a vein, which makes scar tissue form. This scar tissue closes the vein. A closed vein loses its source of blood and dies. After a year or two, the vein is likely to disappear.
Simple laser treatment:
Simple laser vein treatment is done on the outside of your skin. It can treat spider veins and tiny varicose veins just under the skin's surface. Usually, more than one laser session is needed. They are scheduled every 6 to 12 weeks, as prescribed by your doctor. (If you have poor blood circulation feeding these tiny veins, the larger "feeder" vein must first be treated with surgery, endovenous laser or radiofrequency treatment, or sclerotherapy.)
Endovenous laser treatment:
Endovenous laser treatment can treat larger varicose veins in the legs. A laser fiber is passed through a thin tube (catheter) into the vein. While doing this, the doctor watches the vein on a duplex ultrasound screen. Laser is less painful than vein ligation and stripping, and it has a shorter recovery time. Only local anesthesia or a light sedative is needed for laser treatment. (For ligation and stripping, general anesthesia is used to put you to sleep.)
Reasons for the procedure
Varicose veins are not usually a serious health problem, but they can be painful and you may be bothered by the way they look. Your doctor may suggest laser varicose vein surgery if they are sore or inflamed or if the skin over them is irritated.
