Radio Frequency Ablation

What is Radiofrequency Ablation (RFA)?

Radiofrequency ablation (RFA) is a minimally invasive outpatient procedure used to treat varicose veins caused by venous reflux — a condition where the valves in your veins fail to close properly, allowing blood to flow backward and pool in the legs. RFA uses controlled radiofrequency energy to heat the inside of the affected vein, causing it to collapse and seal shut. Once closed, blood is naturally rerouted to healthy veins, restoring normal circulation.

RFA is one of the most widely used and effective treatments for venous insufficiency and varicose veins, offering a safe alternative to traditional vein stripping surgery with significantly less pain and faster recovery.

How Does Radiofrequency Ablation Work?

RFA targets the great saphenous vein (GSV) — the long vein running from the ankle to the groin along the inner thigh. Reflux in the GSV is the most common cause of varicose veins in the legs. When this vein’s valves fail, blood pools in the branch veins below, causing them to twist, bulge, and become varicose.

The Procedure

1. Preparation: The procedure is performed in our office under local anesthesia. Your physician uses duplex ultrasound to map the affected vein and plan the treatment.
2. Access: After numbing the skin, a thin catheter (about the size of a strand of spaghetti) is inserted into the vein through a tiny puncture, typically near the knee.
3. Positioning: Using ultrasound guidance, the catheter is gently advanced up the great saphenous vein to the treatment area in the thigh.
4. Tumescent anesthesia: A dilute local anesthetic solution is injected around the vein to numb the area, protect surrounding tissue, and compress the vein against the catheter for optimal contact.
5. Treatment: Radiofrequency energy is delivered through the catheter tip, heating the vein wall to a precise temperature. As the catheter is slowly withdrawn, the vein collapses and seals shut segment by segment.
6. Completion: The catheter is removed and a small bandage is placed at the insertion site. No stitches are needed.

The entire procedure typically takes 30-60 minutes.

What Happens After the Vein is Closed?

Once the great saphenous vein is sealed, the twisted and bulging branch veins below it lose their source of excess blood flow. Over the following weeks and months, these varicose veins gradually shrink and improve in appearance. Blood that previously flowed through the diseased vein is naturally rerouted to other healthy veins in the leg, restoring normal circulation.

The body gradually absorbs the treated vein over time, so there is no “dead vein” left in your leg.

Who is a Candidate for RFA?

Radiofrequency ablation may be recommended if you have:

• Varicose veins caused by saphenous vein reflux, confirmed by duplex ultrasound
• Symptoms of venous insufficiency, including leg pain, heaviness, swelling, or fatigue
• Failed to find relief with conservative treatments such as compression stockings, leg elevation, and exercise
• Skin changes or ulcers related to chronic venous insufficiency
• Cosmetic concerns about visible varicose veins

RFA is suitable for most patients with saphenous vein reflux. Your vascular specialist will perform an ultrasound evaluation to determine whether RFA is the right treatment for your specific condition.

Benefits of Radiofrequency Ablation

• Minimally invasive: No surgical incision — just a tiny needle puncture
• Local anesthesia only: No general anesthesia or sedation required
• Outpatient procedure: Performed in our office; you go home the same day
• Quick procedure: Typically completed in 30-60 minutes
• Rapid recovery: Most patients return to normal activities the same day or next day
• High success rate: Studies show closure rates above 95% at five years [1]
• Less pain: Significantly less discomfort than traditional vein stripping surgery
• Excellent cosmetic results: No visible surgical scars

What to Expect During Recovery

Recovery from radiofrequency ablation is typically fast and straightforward:

• Day of procedure: You can walk immediately after treatment and are encouraged to do so. Light activities can be resumed the same day.
• First 1-2 weeks: Wear compression stockings as directed (typically during waking hours). Mild bruising, tenderness, or a “pulling” sensation along the treated vein is normal.
• Activity: Walking is encouraged daily. Avoid prolonged standing, heavy lifting, and strenuous exercise for about two weeks.
• Follow-up: A duplex ultrasound is typically performed within the first week to confirm successful vein closure and check for any complications.
• Long-term: Improvement in varicose vein appearance and symptoms continues over several weeks to months.

Potential Risks and Side Effects

RFA is considered very safe with a low complication rate. Possible side effects include:

• Mild bruising and tenderness along the treated vein (common and temporary)
• Temporary numbness or tingling near the treated area
• Sensation of tightness or pulling in the thigh
• Mild skin discoloration (usually temporary)
• Rarely, deep vein thrombosis (DVT) or skin burn

Your physician will discuss all potential risks and answer your questions before the procedure.

RFA vs. Traditional Vein Stripping

Radiofrequency ablation has largely replaced traditional vein stripping surgery as the preferred treatment for saphenous vein reflux. Here’s how they compare:
