Sclerotherapy is the injection of a medication into a vein in order to bring about its disappearance. It works by irritating the lining of the vein such that the vein seals shut, causing the vein to gradually dissolve over several weeks. Sclerotherapy takes about 20 minutes and can be used to treat “spider” veins, reticular and varicose veins. Most people need a few treatments to obtain the best results. Treatments are generally done at about monthly intervals. Compression stockings are usually worn several days after treatment. We ask that you walk, bike, treadmill (or similar activity) about 1 hour daily for a few days.
SCLEROSANTS
Sotradecol, Asclera – Now Available
A variety of medications have been used for sclerotherapy. These medications are called sclerosants since they “sclerose” or close the treated vein. Dr. Zimmet most often uses Sotradecol, Asclera (the recently FDA-approved form of polidocanol) and/or a combination of dextrose and saline. He most often recommends against using hypertonic saline as it causes much more discomfort during treatment and has a significantly higher risk of causing skin ulceration should it be injected outside of the vein.
FOAM SCLEROTHERAPY
Foam sclerotherapy can be useful for treating larger veins. With foam sclerotherapy, Sotradecol or Polidocanol is mixed with air or other gas prior to its injection, creating a foamy solution. This increases its strength and effectiveness. It’s especially important the physician be very knowledgeable and experienced before using foam sclerotherapy.
ULTRASOUND-GUIDED SCLEROTHERAPY
Ultrasound-guided sclerotherapy is used to treat veins below the surface of the skin.
CAUTIONS
Dr. Zimmet strongly recommends using the FDA-approved brands of Sotradecol and Polidocanol rather than compounded versions of these medications. The compounded versions are much less expensive, but not nearly as pure and without the quality control and oversight of the FDA-approved medications.
Results of sclerotherapy are very technique dependent. There is science and a lot of art to performing sclerotherapy. Be sure to ask how experienced the treating physician is.
Finally, not all patients are good candidates for sclerotherapy. If you’d like to learn more about sclerotherapy for spider veins, Austin Dermatologist Dr. Zimmet would be happy to field your questions. Contact us or call to schedule your consultation today at 512.402.6694.
