The gold standard for spider and reticular vein treatment remains surface sclerotherapy.
A very fine needle is used to inject a solution (sclerosant) directly into the veins. This solution causes an inflammatory reaction that causes the lining of the veins to swell and eventually seal off the blood vessel, preventing blood flow. Newer sclerosant medications have greatly reduced the pain, inflammation, and post-procedure discomfort previously associated with surface vein treatment.
