Spider veins and smaller varicose veins can be treated by injections of a sclerosing solution. This solution works by irritating the lining of the vein, causing the vein to seals shut and collapse. The vein then fades over time. The injections require no anesthesia as they are relatively painless, and are usually performed in the doctor’s office. Cotton and compression tape is applied to the injection site, and support stockings may be prescribed by the doctor to promote healing. The injection site may be temporarily bruised or discolored for one to two weeks. Two or more sessions are usually required to achieve maximum results, scheduled at least one month apart.
Risks Related to Sclerotherapy Treatment
Risks related to sclerotherapy are very rare, but can include blood clots in the veins, inflammation, allergic reactions to the sclerosing solution and skin injury that could leave scars. In some cases, skin pigmentation irregularity can occur, which will fade over time. Another reaction that can occur is “telangiectatic matting,” where small reddish blood vessels appear around the treated area. This condition is remedied through additional injections.
