Sclerotherapy involves the injection of a medication into a vein (or cluster of veins). The goal of therapy is to deliberately cause blockage of the vein via chemical injury to the internal lining of the vein.
A variety of medications can be used for injection sclerotherapy. Some of the most commonly utilized agents are hypertonic saline, sodium tetradecyl sulfate – STS (Sotradecol), and polidocanol (Asclera).
Sclerotherapy sessions are office-based, walk-in walk-out procedures that typically take 20-30 minutes. Sclerotherapy procedures can be used to improve the cosmetic appearance of spider veins ( 3mm in diameter).
