Minimally Invasive Varicose Vein Treatment
Varithena procedure is a foam sclerotherapy solution that is used for varicose vein treatment. It’s unique in that it is a non-thermal, non-tumescent alternative to thermal vein ablation, and therefore has distinct advantages over other common vein procedures:
- Immediate symptom relief
- Quick procedure
- Effective in complex veins
- Single needle puncture
- No cutting, no tumescence, no local anesthesia
- No risk of burning or tissue damage
- Minimal pain during the procedure
Our vein specialists answer common questions about the Varithena procedure and explain the role of this unique therapy in our vein treatment armamentarium. Get in touch with us at ProVascularMD to learn more about your veins and your options.
Dr. Michael Lalezarian
Dr. Michael Lalezarian is a double-board certified Vascular Interventional Radiologist specializing in minimally invasive vein treatments. He is a committed partner in the battle against the devastating consequences of venous insufficiency.
“I was referred to Dr. Lalezarian from my orthopedic surgeon for varicose vein treatment options. From the second I walked into the office, I was at ease and felt very welcomed from Kimberly and the staff. Upon meeting the doctor, he was so kind and fully explained my options after the initial ultrasound on both legs. I decided to go with the sclerotherapy and am so happy that I did. The procedures were quick and virtually painless but the results are life changing for me. The pain suffered for so many years and countless sleepless nights are a thing of the past.”

What is Varithena?
Foam sclerosant was approved for use by the FDA in 2013, and since its approval, sclerotherapy with foam has been commonly used to treat venous reflux in the great saphenous vein (GSV) and accessory vessels. Foam sclerotherapy with ultrasound guidance can be used to treat both the cosmetic appearance of varicose veins as well as the persistent symptoms of vein disease, including swelling, pain, aching, throbbing, heaviness, and itching.
How Does Varithena Work?
Because of its foam-based delivery mechanism, Varithena can be used to treat nearly every case of varicose veins, and it has the unique advantage of being able to treat varicose veins that are exceptionally large, lie deep below the surface of the skin, and are highly branched or twisted [1, 2]. Other varicose vein treatments, including thermal ablation and vein glue are not as effective in these scenarios.
What Happens During the Varithena Procedure?
The Varithena procedure is a Varithena injection and only requires a single puncture in the leg, and does not require any cutting or any anesthesia. To start, Polidocanol Endovenous Microfoam (PEM), is injected into the desired vein with a 27 or 30 gauge needle. Sometimes, gas is also injected into the foam mixture. The extremity where the vein is located might be elevated to aid the distribution of the foam mixture. Ultrasound is used to visualize the location of the foam. In large veins like the great saphenous vein, foam is repeatedly injected until a syringe aspirates no more blood to ensure complete coverage. In total, the Varithena procedure takes around 30 to 60 minutes to complete.
After the procedure, you may be asked to wear compression stockings and to limit intense physical activity to help ensure complete closure of the treated veins. Otherwise, you can return to normal daily activities including work immediately after the procedure. Most patients see visible improvement of vein clearance after 1 treatment session, although multiple sessions may be required for complete vein clearance.
Is Varithena Effective?
There have been at least a handful of studies on the durability of Varithena treatment. In one study comparing vein closure rates with laser ablation, conventional surgery, and foam sclerotherapy, vein closure rates at one year post treatment were 88.5% for endovenous laser ablation, 88.2% for conventional surgery, and 72.2% for foam sclerotherapy . This study suggested that Varithena wouldn’t be as durable as other treatments. However, in another study, 90% of great saphenous veins remained close after two sessions of foam sclerotherapy over an average 3.25 years of follow-up , suggesting that Varithena is just as good if not better than alternatives. It’s also interesting to note that varicose vein recurrence does not always cause symptoms. One study found that 70% of patients did not experience clinical vein symptoms again even after a treated vein reopened .
Looking at all of the evidence, we think it’s fair to say that treatment efficacy is approximately equal between the different types of vein treatment, both in terms of symptom relief and durability.
