Injection sclerotherapy is a procedure used to treat spider veins and small varicose veins. Sclerotherapy involves injecting a solution into the spider veins in order to close the veins and cause it to disappear. Injection sclerotherapy has been used to treat varicose veins since the 1930's. The techniques have improved over the last few decades.
Sclerotherapy requires a consultation with one of our expert doctors to assess the problematic vein or lymph vessel. The procedure does not usually require anesthesia or any special preparation. People should follow the doctor’s instructions before surgery since it might be necessary to avoid lotions or oils beforehand.
During the treatment, the person lies on their back with their legs up. A doctor cleans the area, then an extremely fine and usually painless needle is placed into the vein. A small amount of sclerosing solution is then injected into the vein. This solution causes irritation of the lining of the vein wall, which causes the vein to spasm and become a small fibrous thread, resulting in permanent closure of the vein.
When the injection is complete, the doctor will massage the area to prevent blood from re-entering the vein. The individual may need to wear a pad or compression stockings in the area. In most cases, someone will need follow-up treatment to collapse a vein fully. If there are several varicose veins, numerous treatments may be the only way to get rid of them. After the treatment, people should remain active to prevent blood clots from forming. Most will also need to avoid sunlight, which can cause dark spots on the treated area. Some people experience tenderness or bruising at the site of the injection, but recovery is otherwise relatively easy.
The closed veins will be absorbed by the body and typically disappear in 1-3 months.
