Sclerotherapy or leg vein treatment is a procedure used to treat undesired spider and small-to-medium varicose leg veins. This condition is most often found on thighs, around knees, on calves, and/or on the ankles. These veins do not serve a specific purpose so they can be removed without posing any health risks. This procedure consists of a series of repeated injections of a sclerosing solution into the veins. The sclerosing solution irritates the inner lining of the vein and causes the vein to harden and eventually scar away. Usually 3-5 treatments are required for best results with 4-6 weeks treatment intervals. Patients are required to wear compression stocking for up to 2 weeks after the treatment for best results and refrained from sun exposure to treated areas to prevent pigmentation side effects.
Lasers are also utilized in the treatment of blood vessels, especially "broken capillaries" on both the face and legs. Larger blue vessels also respond to laser therapy but carry more risk of skin changes than do smaller vessels due to the amount of energy required. Leg veins that are too small to be treated by injections may be treated with lasers. One to three treatments are usually required 2-4 weeks apart for the best results. Most patients may require a combination of sclerotherapy and laser treatments to achieve the best results.
