What is sclerotherapy?
Sclerotherapy is a treatment for spider veins and small varicose veins in your legs. It involves injecting small doses of a chemical into your veins. The chemical irritates the lining of your veins, which causes them to shrink and eventually disappear. Your body redirects blood flow to other veins in your legs.
Sclerotherapy has some risks and potential complications. is only one method used to treat varicose veins. Discuss all of your treatment options with your doctor to understand which options are right for you.
Why is sclerotherapy performed?
Your doctor may recommend sclerotherapy to eliminate or minimize spider veins and small varicose veins. Some people seek sclerotherapy for cosmetic reasons when their veins are protruding or unsightly. Others are seeking relief from discomfort or painful sensations, such as burning, aching, swelling, soreness and cramping.
Veins are blood vessels that carry blood from your body back to your heart. There are valves inside veins that help direct blood back to your heart. When the valves are damaged or weakened, blood can pool in your veins causing them to swell and weaken. This results in varicose and spider veins.
Varicose veins can look blue, twisted and bulging, and feel uncomfortable. Spider veins are smaller, closer to your skin surface, and look like small, jagged lines or starbursts. They tend to cause less discomfort and bulging.
Your doctor may only consider sclerotherapy for you if other treatment options with less risk of complications are ineffective. You may be able to prevent spider veins and varicose veins by exercising, losing weight, and wearing compression stockings. Ask your doctor about all of your preventive and treatment options and consider getting a second opinion before deciding on sclerotherapy.
