Foam Chemical Ablation

One relatively new treatment we offer is Varithena, a specific type of foam ablation. Varithena has been in development for about a decade, but it’s only recently become widely used. If you suffer from varicose veins, contact us to see whether you are a good candidate for a chemical foam ablation treatment.

What Is Chemical Foam Ablation?

Foam chemical ablation using Varithena is very similar to other forms of sclerotherapy. These treatments involve the injection of a chemically abrasive foam directly into the vein. The foam irritates the vein’s wall, encouraging the growth of scar tissue that will close off the vein.

Where Varithena differs from other types of sclerotherapy is the chemical makeup of the foam itself. Varithena is the grand name of a polidocanol injectable foam, and the only foam approved by the FDA for treatment in the grand saphenous vein. Because the chemical makeup of the foam is different from that used in other types of sclerotherapy, Varithena may be useful for people who are unable to use other treatments.

Is Varithena Right For Me?

Every patient’s situation is unique, and Varithena is not right for everyone. Patients with blood clotting disorders in particular should avoid these treatments. However, a different and equally effective treatment may be available.
