Sclerotherapy is a technique that has been around for decades to treat spider veins and some smaller varicose veins. This procedure involves injecting a sclerosing solution directly into the small veins. As the solution comes into contact with the blood vessel, it irritates the blood vessel and causes it to seal off so that blood can no longer pass through the vein. After several weeks, many of the treated vessels will visibly disappear. Dr. Fazadmehr uses Acelera (Polidochol) treatments. Asclera is indicated to sclerose uncomplicated spider veins (varicose veins ≤1 mm in diameter) and uncomplicated reticular veins (varicose veins 1 to 3 mm in diameter) in the lower extremity. Asclera^® has not been studied in varicose veins more than 3 mm in diameter.
