When considering varicose vein treatment, many patients assume the only options are surgical stripping or heat-based lasers. However, medical technology has evolved significantly. At Florida Vein Center, Dr. Federico Richter utilizes Varithena®—an advanced, non-thermal microfoam treatment that safely eliminates diseased veins without lasers, heat, or incisions.
If you are looking for a gentle, highly effective solution for twisting or hard-to-reach varicose veins, this tech spotlight explains why Varithena is a preferred choice for our patients in Bradenton and Sun City Center.
What is Varithena® and how does it work?
Varithena® is an FDA-approved prescription microfoam (polidocanol injectable foam). Unlike liquid treatments that can dilute quickly in the bloodstream, Varithena's specialized foam filling expands to fit the exact shape of the diseased vein.
The procedure is highly precise:
- Dr. Richter uses live ultrasound guidance to administer a small amount of the microfoam into the target vein through a tiny access point.
- The foam gently displaces the pooled blood and causes the diseased vein wall to collapse and close.
- Once the vein is sealed, your body automatically redirects blood flow to nearby healthy veins, immediately improving your circulation.

What makes Varithena® different from laser treatment?
Varithena offers several unique clinical advantages, particularly for complex or winding vein structures:
- No Heat (Non-Thermal): Traditional laser or radiofrequency treatments rely on high heat to seal veins, which carries a small risk of skin burns or nerve irritation. Varithena works chemically and physically, completely eliminating heat-related side effects.
- Treats Curved, Tortuous Veins: Lasers use a rigid fiber optic cord that must travel in a straight line. Because Varithena is a flexible foam, it easily flows through twisting, "tortuous" veins that lasers simply cannot reach.
- Minimal Numbing Required: Because there is no heat, Varithena does not require the extensive "numbing fluid" injections along the entire length of the leg that laser treatments require.
What is the recovery time for Varithena®?
Recovery is immediate. The entire procedure takes less than 45 minutes in our office. Because there are no surgical incisions, you will only have a small bandage at the injection site.
Patients are encouraged to walk immediately after the procedure and can typically return to work, driving, and normal daily activities the exact same day. You will wear a lightweight compression stocking for a short period to assist with the initial healing process.
Is Varithena® covered by insurance or Medicare?
Yes. When Varithena is used to treat symptoms of venous insufficiency—such as leg pain, throbbing, swelling, or heaviness—it is typically covered by Medicare and most private insurance plans. During your initial screening, our team will perform a diagnostic ultrasound to verify your insurance eligibility.
