Ultrasound Guided Sclerotherapy is a treatment method used to treat veins that are too small for laser treatment. Using ultrasound to guide placement, a liquid sclerosing agent is injected into the vein. The sclerosing solution causes the vein to blanch (turn white) and irritates the vein lining, causing the vein to contract. This contraction squeezes most of the blood out. Some of the blood clots and is reabsorbed. Healing over the next two weeks turns the vein into scar tissue and it will gradually disappear. Usually more than one treatment is required at 6-8 week intervals. Our providers will encourage you to wear compression stockings for one week for optimum results.
