- Sclerotherapy (pronounced sklair-o-THAIR-uh-pee) is a medical procedure that has been used since the 1930s6 to treat varicose and spider veins. As the standard of care, it is considered one of the safest and most effective treatments for removing unwanted leg vein.
- The procedure involves injecting a solution directly into a vein, causing the treated vein to seal shut and fade from view over time. The treated blood vessel (vein) is then naturally resorbed by the body.
- Asclera® is a specific type of solution used for sclerotherapy that has anesthetic properties and may help to reduce procedure discomfort.
- Marketed as Aethoxysklerol in Europe for more than 50 years, Asclera® was FDA-approved in the US in 2010.
Small varicose veins, also known as reticular veins, are small blood vessels that measure between 1 to 3 mm in diameter and are also known as feeder veins. Small varicose veins can enlarge as a result of increased pressure in the vein or from weakened vein valves. You may have only small varicose veins or both small varicose and spider veins at the same time.
Spider veins are very small, fine, red or blue veins that are less than 1 mm in diameter. They lie closer to the surface of the skin than varicose veins and may resemble a thin red line, tree branches, or spider patterns. Spider veins can be found on the legs and face and may cover a small or large area.
Sclerotherapy is a minimally invasive procedure administered by your healthcare provider to treat uncomplicated spider veins and uncomplicated reticular veins. The treatment involves the injection of a solution into affected veins.
