Varicose veins are twisted, enlarged veins near the surface of the skin. They are most common in the legs and ankles. Varicose veins are caused by weak valves and veins in your legs that produces significant discomfort and heaviness in the legs and in some cases even swelling.
Sclerotherapy involves injecting a solution directly into the vein. The sclerotherapy solution causes the vein to scar and collapse, forcing blood to reroute through healthier veins. The collapsed vein is reabsorbed into local tissue and eventually fades. After sclerotherapy, treated veins tend to fade within a few weeks, although occasionally it may take up to a month to see the full results.
The procedure takes 20 to 30 minutes, requires no anesthesia, and is associated with minimal discomfort. Elastic prescription stockings must be worn after the procedure for two to four weeks to ensure pressure that helps in resolving the veins. In some instances, several sclerotherapy sessions may be needed.
