Varithena is a low nitrogen Polidocanol 1% injectable foam dispensed from a canister device. Varithena is the only FDA-approved foam for the treatment of refluxing or incompetent saphenous and accessory saphenous veins and visible varicose veins of the lower extremities. Its proprietary method of preparation results in a uniform, cohesive foam. The specific gas mixture of oxygen:carbon dioxide makes Varithena the only standardized, low nitrogen foam. It results in closure of the vein with venous reflux which can help improve the symptoms of chronic venous insufficiency. It also can help with diminishing the appearance of varicose veins.
Treatment is minimally invasive performed in the office setting. Utilizing ultrasound for guidance, a small amount of local anesthesia is infiltrated and needle access is obtained in the refluxing vein. The sclerosant foam is then injected into the vein with resulting in its closure. There is no need for large volumes of tumescent local anesthesia or sedation. Patients can return to normal activities and work immediately following treatment. Compression stockings are also recommended to be worn following treatment.
