Sclerotherapy is used to treat spider veins and small varicose veins. It involves injecting a solution directly into the vein. The solution irritates the lining of the vein causing it to adhere together and the blood to clot. The blood reroutes through normal veins. The treated veins fade over a few weeks. Often, multiple sclerotherapy treatments may be required to achieve the desired cosmetic results.
The procedure is performed in the office and does not require local anesthesia. A very tiny needle is used for the injection. Patients can walk immediately after the procedure and return to normal activities. Compression stockings should be worn for about 2 weeks after the procedure.
