Varithena® Foam Sclerotherapy
An FDA-approved microfoam that closes diseased veins without heat, catheters, or surgery — ideal for twisted veins other treatments can't reach.
What Is Varithena?
Varithena® is a prescription microfoam made from polidocanol, a medication used in vein care for decades. It is FDA-approved to treat the great saphenous vein system — a common source of varicose veins — and the visible varicosities connected to it.
Unlike thermal ablation, Varithena uses no catheter and no heat. A small volume of fine, uniform foam is injected into the diseased vein under ultrasound guidance. The foam displaces the blood, treats the vein wall, and the vein closes. Blood reroutes to healthy veins, and the treated vein is gradually absorbed by the body.
Because foam flows where a stiff catheter cannot, Varithena is especially useful for tortuous (twisted) veins and for some veins that have returned after earlier treatment.
Who It's For — and Who It's Not For
Varithena may be a good fit if:
- Your refluxing vein is too twisted or too close to the skin for a heat-based catheter treatment like RFA or EVLA.
- You have recurrent varicose veins after a previous procedure.
- You prefer a needle-only treatment without tumescent anesthesia injections.
It is generally not the first choice for tiny cosmetic spider veins (visual sclerotherapy handles those), and it is avoided in patients with a known allergy to polidocanol or an active blood clot. Some very large, straight saphenous veins may still be better served by thermal ablation. Your duplex ultrasound — performed personally by Dr. Tadepalli — determines which tool fits your anatomy.
What to Expect
Before
You'll have a consultation and a duplex ultrasound to map your reflux, followed by insurance verification and pre-authorization before any treatment is scheduled. No referral is needed. Because coverage criteria for Varithena vary by plan, we confirm your benefits up front — costs made clear up front.
During
Treatment is a 30–45 minute office visit. After a small numbing injection at the access site, Dr. Tadepalli places a fine needle or tiny cannula into the vein and injects the microfoam while watching it move through the vein on ultrasound in real time. Gentle pressure and leg positioning help direct the foam. There is no heat, no tumescent anesthesia, and no incision.
After
A compression stocking is applied and you walk out the same day — walking immediately afterward is part of the protocol. Back to life the same afternoon.
Recovery
Most patients return to light normal activity right away. We ask you to wear compression as directed, walk daily, and avoid heavy exercise and long periods of inactivity for a short time after treatment — your specific plan will be reviewed with you at the visit.
Some firmness, tenderness, or lumpiness along the treated vein is common for a few weeks as the vein seals and is absorbed. A follow-up ultrasound checks the result, and some patients benefit from an additional session or a complementary treatment such as ultrasound-guided sclerotherapy for smaller branches.
Risks & Considerations
Varithena is well tolerated, but results vary and risks exist. The most common effects are temporary: bruising, aching, tenderness, and firmness along the treated vein, plus possible skin pigmentation (a brownish staining that usually fades over months but can persist). Superficial phlebitis can occur. Rarer risks include allergic reaction to polidocanol, deep vein thrombosis (DVT), and — very rarely with any foam sclerosant — visual disturbance or migraine-like symptoms shortly after injection, which typically resolve. Ultrasound guidance and careful foam volumes are the main safeguards.
If a non-thermal option appeals to you but foam isn't the right match, VenaSeal™ adhesive closure is another heat-free alternative we offer in the same office.
"Varithena earns its place in my practice on the difficult cases — the twisted, branching veins a catheter can't follow. Watching the foam trace the whole vein on ultrasound is exactly the precision I want."— Dr. Satish Tadepalli, MD, MPH, DABVLM
