Radiofrequency Ablation (RFA) is a minimally invasive procedure used to treat chronic venous insufficiency and symptomatic varicose veins. It is considered a gold-standard treatment for venous reflux, a condition in which faulty vein valves allow blood to flow backward and pool in the legs. This pooling increases venous pressure and can lead to leg swelling, heaviness, aching, skin discoloration, and even venous ulcers.
RFA works by using controlled thermal (heat) energy to close diseased veins. Once the abnormal vein is sealed, blood is naturally redirected to healthy veins, improving circulation and relieving symptoms.
RFA is performed in the office setting under local anesthesia and typically takes less than one hour.
Radiofrequency Ablation Procedure
Radiofrequency Ablation is performed under ultrasound guidance with local anesthesia.
The procedure begins with a small needle insertion into the affected vein, commonly the great saphenous vein (GSV) or small saphenous vein (SSV). A thin catheter is then advanced through the vein using real-time ultrasound imaging.
Once the catheter is positioned properly, a special anesthetic solution (tumescent anesthesia) is placed around the vein. This serves multiple purposes: it numbs the area, protects surrounding tissues, and allows the vein to collapse around the catheter.
The radiofrequency catheter then delivers controlled heat energy along the length of the diseased vein. The heat causes the vein walls to collapse and seal shut. Over time, the body naturally absorbs the closed vein.
After treatment, blood flow is redirected to healthy veins, reducing venous pressure and improving symptoms.
Conditions Treated with RFA
Radiofrequency Ablation is commonly recommended for patients with:
-
Chronic venous insufficiency
-
Symptomatic varicose veins
-
Venous reflux confirmed by duplex ultrasound
-
Leg heaviness or fatigue
-
Persistent leg swelling
-
Skin discoloration around the ankles
-
Venous stasis dermatitis
-
Venous ulcers
Benefits of Radiofrequency Ablation
-
Minimally invasive procedure
-
No hospital stay required
-
Performed under local anesthesia
-
Minimal scarring
-
Quick recovery time
-
High success rates
-
Significant symptom relief
Compared to traditional vein stripping surgery, RFA offers less discomfort and a faster return to normal activities.
What to Expect After the Procedure
Patients are encouraged to walk immediately after the procedure to promote healthy circulation. Compression stockings are typically worn for a period of time to aid healing and optimize results.
Most patients return to normal daily activities within 24 hours. Mild bruising, tightness, or tenderness along the treated vein is common and temporary.
Follow-up ultrasound is performed to confirm successful closure of the treated vein.
When is RFA Recommended?
Your vascular specialist may recommend Radiofrequency Ablation if you experience:
-
Persistent leg swelling
-
Aching or heaviness that worsens throughout the day
-
Visible varicose veins
-
Skin changes near the ankles
-
Non-healing venous ulcers
-
Symptoms that do not improve with compression stockings
Early treatment can prevent progression of chronic venous insufficiency and reduce the risk of long-term complications.
