Sclerotherapy (Foam & Liquid)
Sclerotherapy involves injecting an irritant chemical into a problematic vein. The principle of injections is to fill the vein with a solution that will empty the vein of blood and cause the vein wall to become inflamed. As a result, the walls of the vein scar together and the vein will become obliterated and will no longer be visible. You may notice an improvement in as little as 3 weeks, but most veins need 2-3 months of healing time. Support stockings are required for 2 weeks following your treatment.
Almost always, multiple treatments are required. Individual treatment plans are made based on the size and severity of your venous disease. Because the veins of the lower extremities are under high pressure, there is a tendency for recurrence of spider veins. This requires an individual to understand the need to return for minor additional treatments on a yearly basis.
When larger veins need to be injected, we sometimes have to inject a thicker substance called foam. Foaming the sclerosing solution allows the chemical to make contact with the vein wall longer therefore allowing for a successful treatment.
