Sclerotherapy is a proven medical procedure that has been in use since the 1930s. It effectively treats varicose and spider veins and is often considered the treatment of choice for small varicose veins. 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. 50 percent to 80 percent of injected veins may be eliminated with each injection session.
The sclerotherapy procedure takes about 30 to 45 minutes. The treatment is safe, however, mild discomfort may occur when the veins are injected, and a cramping sensation may be felt for 1 to 2 minutes when larger veins are injected. . Bruising may also occur around the injection site and can last several days or weeks.
Patients should wear compression stockings for one to three weeks after treatment.
