Leg Vein Treatment


Sclerotherapy is a treatment for varicose veins and spider veins where medication (called Sotradecol) is injected directly into the vein causing it to immediately shrink.  Dr. George Groleau is the physician currently providing this treatment within our practice. Patients interested in treatment should contact our Lime St. office for prior consultation and  possible treatment.


Unwanted leg veins are injected with the sclerosing agent, with a very thin needle, and the vein immediately shrinks. After the immediate shrinkage of the vein occurs, the vein will continue to dissolve over a period of a few weeks as the body naturally proceeds to absorb the sclerosed vein.

After treatment, your leg is wrapped up in compression bandages or a stocking to keep slight pressure on the area. Our doctors advise sclerotherapy patients to walk as often as possible for 2 weeks after the initial sclerotherapy treatment to allow the medication to flow through the vein.

The side effects of a sclerotherapy treatment are generally minimal. In some cases, patients will experience some itching around the treated area. Additionally, some patients experience raised red areas around the injection site, or slight bruising. Dr. Patricia Groleau will further explain possible side effects of sclerotherapy if you have more questions or concerns.


Lasers can be used for leg veins not erased with sclerotherapy, but this is usually not necessary. Other offices may use lasers for leg veins if they are not confident with sclerotherapy. Since our doctors are experts in sclerotherapy, we start with sclerotherapy treatments (before using lasers) because it offers the best vein removal results. Our doctors will further explain laser options with you if laser treatments are necessary.


What causes leg veins?

Leg veins are a result of a backup of blood caused by weak or damaged valves in the veins. The heart pumps blood filled with oxygen and nutrients to the whole body through arteries. Veins then carry the blood back to the heart. Valves inside the veins act as one-way flaps to prevent blood from flowing backwards as it moves up your legs. If the valves become weak, blood can leak back and collect there, causing the veins to get bigger and therefore visible. Leg veins are blue because they are deep and large.

Scleroptherapy is the most common procedure performed on spider veins or varicose veins. It is the most effective treatment available today for elimination of large veins. Not only is it effective in eliminating the unsightly vein but it actually helps prevent the vein from coming back. The sclerosing agent also closes the smaller veins (feeder veins) that contributed to the larger one targeted for treatment. This greatly reduces the odds that the vein will reappear.
