VenaSeal vs. Radiofrequency Ablation (RFA)
Both close the same leaking veins. RFA uses radiofrequency heat and numbing fluid placed along the vein; VenaSeal uses a medical adhesive and no heat. Both are done in the office under ultrasound guidance, and most patients go back to normal activities the same day. The ultrasound, and your own preferences, decide which one fits.

How they compare
| RFA (ClosureFast) | VenaSeal | |
|---|---|---|
| How it closes the vein | Radiofrequency energy delivered through the catheter heats the vein wall, and the vein collapses and seals shut. | A small amount of medical adhesive is delivered into the vein, and light pressure is applied on the skin to seal the vein walls together. |
| Numbing | Local anesthetic plus tumescent anesthesia, a numbing solution placed around the vein. | Local anesthetic only. Typically, only one needle stick is needed for the whole procedure. |
| Sedation | Available if you want it. | Available if you want it, but rarely requested. |
| Procedure time | Typically 30–60 minutes per leg. | Usually about 20–30 minutes per leg. |
| Time in the office | About 60–90 minutes in total. | About an hour in total. |
| Back to normal activities | Most patients the same day. | Most patients the same day. |
| Strenuous exercise | Usually after 1–2 weeks. | Usually after about a week. |
| Compression stockings | Day and night for the first 24–48 hours, then during the day, for 1–2 weeks. | During the day for about one week. |
| Follow-up ultrasound | Within the first week. | Within the first week. |
| Insurance | Covered by most plans when ultrasound confirms venous insufficiency, often after a trial of compression stockings. | Coverage varies more from plan to plan than coverage for RFA. |
How Dr. Elbaridi chooses
Dr. Elbaridi may choose VenaSeal when you would rather avoid heat and the numbing injections along the vein, or when the vein runs close to a nerve, lower in the leg, where heat could irritate it. RFA is often chosen when your insurance covers it more readily, and Varithena suits veins that twist or are hard to reach with a catheter.
Dr. Elbaridi performs RFA, VenaSeal and Varithena, so the choice comes from your ultrasound, your insurance and your preferences, and he talks it through with you.
Who can have which
Most patients with a leaking saphenous vein can have either one. An allergy to the adhesive rules out VenaSeal, and vein anatomy that isn’t suited to a catheter may point to Varithena instead of either.
What both have in common
- Every visit starts with a venous duplex ultrasound, so treatment is matched to what is actually happening in your veins.
- Dr. Nidal Elbaridi performs every procedure in the office at our South Loop and Streeterville locations.
- No general anesthesia is required.
- A follow-up duplex ultrasound within the first week confirms the treated vein has closed and that the deep veins are healthy and free of blood clots.
- A vein that has been successfully closed usually stays closed. However, new varicose veins can develop over time if the underlying tendency toward venous insufficiency continues.
In Dr. Elbaridi’s experience, both close the vein well when they are matched to the right vein; the choice is about comfort, recovery and coverage rather than which works better.
Insurance
Medical vein treatment is covered by most insurance when ultrasound confirms venous insufficiency. We verify benefits and pre-authorize before your procedure, so there are no surprise bills afterward.
Coverage for VenaSeal varies more from plan to plan than coverage for RFA: some insurers cover it the same way, and others don’t cover it yet. We check your plan before you choose, and if VenaSeal isn’t covered, RFA or another covered option can usually close the same vein.

VenaSeal or RFA: questions, answered
Which one is less uncomfortable?
Both are done with local anesthetic, and most patients tolerate either well. VenaSeal usually needs only one needle stick, while RFA uses several small numbing injections along the vein.
Which one has the faster recovery?
Most patients return to normal activities the same day after either one. VenaSeal usually means a shorter stretch in compression stockings and a slightly earlier return to strenuous exercise.
Do I get to choose, or do you decide?
Both. Dr. Elbaridi tells you which options fit your ultrasound and your insurance, and when more than one fits, your preference decides.
Can you use both on the same leg?
Sometimes. Different veins in the same leg can be treated with different methods, and Varithena, sclerotherapy or microphlebectomy may be added for the branches.
Is VenaSeal glue safe to leave in my body?
VenaSeal uses a medical-grade adhesive made for use inside veins. Only a small amount is used, and it stays inside the closed vein, which is replaced by scar tissue over time. If you have had a reaction to an adhesive before, tell Dr. Elbaridi at your evaluation.
Are both covered by insurance?
Coverage for VenaSeal varies more from plan to plan than coverage for RFA: some insurers cover it the same way, and others don’t cover it yet. We check your plan before you choose.
