What Is Radiofrequency Ablation?
If your doctor has mentioned radiofrequency ablation — or RFA — you may be wondering exactly what happens during the procedure and what it means for you. In plain terms, RFA is a minimally invasive treatment that uses controlled heat energy to close off diseased veins from the inside. There are no large incisions, no general anesthesia, and no hospital stay required. At Coastal Vascular Center, the entire procedure is performed right in our office.
Here is how it works. Dr. Ayar inserts a thin, flexible catheter — essentially a small tube — through a tiny puncture in the skin and into the diseased vein. Once the catheter is in place, it delivers radiofrequency energy that gently heats the vein wall. The heat causes the wall to contract and seal shut. Over the following weeks, your body naturally absorbs the closed vein. Blood that previously traveled through that diseased vessel simply reroutes through healthier veins nearby — which is exactly what healthy circulation looks like.
For patients who used to face vein stripping surgery — a procedure that involved physically pulling veins out of the leg through incisions — RFA represents a significant step forward. It achieves the same outcome through a far less invasive path.

What Conditions Does RFA Treat at Coastal Vascular Center?
At Coastal Vascular Center, radiofrequency ablation is used exclusively to treat vein disease in the legs. Dr. Ayar uses RFA for the following conditions:
Varicose Veins
Varicose veins are the twisted, rope-like, often bluish or purple veins that bulge visibly beneath the skin. They develop when the small valves inside a vein stop working correctly. Healthy valves act like one-way doors, keeping blood moving toward the heart. When those valves fail, blood pools in the vein, causing it to stretch and distort. Beyond the appearance, varicose veins often cause aching, heaviness, throbbing, and swelling, especially after prolonged standing.
Chronic Venous Insufficiency (CVI)
Chronic venous insufficiency is the underlying condition that most commonly causes varicose veins. When the venous valves fail, and blood cannot flow efficiently back to the heart, pressure builds in the legs. Over time, that pressure leads to persistent swelling, a heavy or fatigued feeling in the legs, skin discoloration, and, in more advanced cases, venous ulcers. RFA treats the specific veins responsible for that reflux.
Great Saphenous Vein Reflux
The great saphenous vein runs along the inner surface of the leg from the ankle up to the groin. It is the most commonly treated vessel with radiofrequency ablation, and for good reason — when this vein develops reflux, it is often the source of widespread varicose veins and venous insufficiency symptoms throughout the leg.
A Note on Spider Veins
Spider veins — the small, superficial web-like clusters of red or purple veins — are generally too small for RFA. For these, sclerotherapy is often the more appropriate treatment. Coastal Vascular Center offers both RFA and sclerotherapy, and Dr. Ayar may recommend one or both depending on what your evaluation reveals.
How the Procedure Works
Many patients feel more at ease once they understand what to expect during the appointment. Here is a step-by-step look at what happens during a radiofrequency ablation procedure at Coastal Vascular Center.
First, the leg is cleansed, and a small area of skin is numbed with a local anesthetic. You are fully awake throughout the procedure — there is no sedation required.
Using real-time ultrasound imaging as a guide, Dr. Ayar inserts the thin catheter through a tiny puncture in the skin and advances it into the diseased vein. Ultrasound guidance allows him to see exactly where the catheter is at every point during the procedure.
Next, a dilute numbing solution — called tumescent anesthesia — is injected along the length of the vein. This serves two purposes: it protects the surrounding tissue from heat, and it compresses the vein tightly around the catheter to improve contact with the vein wall.
The catheter then delivers radiofrequency energy at a controlled, precise temperature. As the vein wall heats, it contracts and seals shut. Dr. Ayar slowly withdraws the catheter, treating the full length of the vein from the bottom up.
Once the procedure is complete, the treated vein is permanently closed. Over the next several weeks, your body absorbs it. Blood circulation naturally shifts to neighboring healthy veins — an adjustment your body handles on its own.
The entire appointment typically takes 45 to 60 minutes. When it is over, you walk out of the office.
What to Expect: Before, During, and After
Before Your Procedure
Every RFA procedure at Coastal Vascular Center begins with a thorough consultation and a duplex ultrasound — an imaging exam that maps the veins in your legs and identifies exactly where reflux is occurring. This step is not optional. Dr. Ayar will not recommend a procedure without first understanding the full picture of your venous anatomy.
On the day of your procedure, wear comfortable, loose-fitting clothing. Avoid applying lotions or moisturizers to the leg being treated.
During the Procedure
Most patients describe the experience as mild pressure or occasional warmth. Tumescent anesthesia effectively minimizes discomfort. You remain awake and can communicate with Dr. Ayar throughout — if anything feels uncomfortable, say so.
After the Procedure
You will leave the office wearing compression stockings, which you will need to wear consistently for 1 to 2 weeks following the procedure. Compression supports healing and helps the body process the treated vein.
You can walk immediately after the procedure. Most patients return to their normal daily activities within a day or two. For a short period, Dr. Ayar will ask you to avoid strenuous exercise and prolonged sitting or standing in one position.
A follow-up ultrasound is scheduled after the procedure to confirm that the treated vein has closed properly.
As for results, treated veins typically fade and become invisible over several weeks to a few months. Many patients notice relief from symptoms — the heaviness, aching, and swelling — within just a few days of the procedure.
The Benefits of RFA at Coastal Vascular Center
Radiofrequency ablation has become the preferred approach for treating venous reflux disease for a straightforward reason: it works well, and the recovery is brief.
Because the procedure requires only a small puncture rather than surgical incisions, patients avoid the risks and recovery time that come with traditional vein stripping surgery. There is no general anesthesia, no hospital admission, and no overnight stay. You schedule an appointment, have the procedure done, and go home the same morning.
The clinical track record is strong. Studies consistently show a 90 to 98 percent vein closure rate at two years. Most patients are back to their regular routine the following day. Long-term results are favorable, particularly when combined with the compression and lifestyle guidance Dr. Ayar provides as part of your follow-up care.
The use of real-time duplex ultrasound throughout the procedure adds an important layer of precision and safety — Dr. Ayar can see exactly what he is doing at every step, thereby reducing risk and improving accuracy.

Is RFA Right for You?
Not every patient with varicose veins or leg symptoms is automatically a candidate for RFA, and Dr. Ayar does not approach it that way. Every patient at Coastal Vascular Center undergoes an individual evaluation, a thorough consultation paired with a duplex ultrasound, before any treatment is recommended.
Good candidates for RFA are typically patients with symptomatic varicose veins, venous insufficiency with reflux confirmed by ultrasound, or leg heaviness, aching, or swelling that interferes with their daily comfort and quality of life.
Some patients have vein patterns that warrant sclerotherapy instead of, or in addition to, RFA, depending on the size and location of the affected veins. Dr. Ayar will discuss all of this with you at your consultation.
If you have been living with varicose veins or unexplained leg symptoms and have never had a vascular evaluation, the most important step is simply to come in. Many patients are surprised to learn their symptoms have a treatable cause.
