Varicose veins are more than just a cosmetic concern. For many people, they cause real discomfort, aching, swelling, fatigue, and skin discoloration, all of which can disrupt daily life. Millions of Americans live with chronic venous insufficiency, the underlying condition where blood pools in the legs due to malfunctioning valves in the veins.
The good news? We now have advanced, minimally invasive solutions to treat varicose veins effectively, without the scars or recovery of traditional vein stripping. Venous Laser Ablation (VLA) and Radiofrequency Ablation (RFA) are two leading procedures reshaping how we treat these conditions for long-term relief.
Venous Laser Ablation (VLA) is a high-precision procedure that uses laser energy to close off faulty veins. Under ultrasound guidance, a thin fiber is guided into the affected vein. Once it’s in position, laser light heats the vein wall, causing it to collapse and seal shut.
By stopping blood from flowing through the malfunctioning vein, the body naturally reroutes circulation through healthier vessels. Over time, the treated vein is absorbed into surrounding tissue, a safe and efficient process.
VLA is typically used for larger veins like the great or small saphenous veins that show significant reflux and symptomatic burden. It’s performed in an office or outpatient setting using local anesthesia.
Radiofrequency Ablation (RFA) operates on a similar principle but uses heat generated by radiofrequency waves instead of laser light. A catheter is inserted into the problematic vein under ultrasound guidance, and radiofrequency energy heats the vein walls, causing controlled thermal damage. This leads to vein closure and redirection of blood flow.
RFA has gained popularity for its consistent outcomes, ease of use, and comfort. Like VLA, it’s minimally invasive, performed under local anesthesia, and has a fast recovery profile.
Whether using light in VLA or radio waves in RFA, both procedures rely on the same underlying principle, thermal ablation. Here’s a simplified step-by-step overview:
Using duplex ultrasound, we assess the anatomy and determine which veins are affected and whether they show reflux (backward flow).
Local anesthesia is administered, and the target vein is accessed through a small puncture site, usually near the knee or ankle.
Either a laser fiber (VLA) or RFA catheter is inserted into the vein. As it’s activated, thermal energy heats the vein from the inside, causing it to collapse and seal.
After treatment, compression stockings are applied to help healing and minimize bruising. Most patients walk out of the procedure room and return to normal activities within 24–48 hours.
Ideal candidates are individuals who:
We often evaluate each patient with a detailed ultrasound mapping session to ensure we’re targeting the right veins in the right way.
Most patients are surprised at how straightforward and comfortable the procedures are. Here’s what a typical experience looks like:
Our team provides detailed post-procedural care instructions, including compression stocking wear duration (usually 7–14 days), walking regimens, and follow-up visits.
While generally safe, complications may include:
We minimize these risks through careful patient selection, precise technique, and close post-procedure follow-up.
Recent innovations have improved both VLA and RFA outcomes significantly. Laser wavelengths have evolved from 810 nm to 1470 nm, reducing heat dispersion and discomfort. Similarly, RFA catheters with temperature-controlled feedback systems improve precision and safety.
Clinical guidelines from respected organizations like the Society for Vascular Surgery and American College of Phlebology reinforce these advancements with strong recommendation levels.
Peer-reviewed studies consistently report long-term vein closure rates of over 90% with either modality.
After treatment, we see considerable improvement in symptoms such as leg fatigue, cramps, swelling, and discoloration. Most patients resume regular activity quickly, with some even reporting an immediate reduction in heaviness.
Follow-up ultrasound is typically performed within a week to confirm treatment success. In the long term, patients often experience durable results with symptom relief that can last years. Secondary treatments are rarely needed, but if required, they can be easily performed.
Maintaining leg health post-procedure involves regular walking, weight control, avoiding prolonged standing, and following through with compression wear if prescribed.
If you’re struggling with aching, unsightly, or swollen veins, don’t wait. Modern vein treatments like VLA and RFA offer safe, definitive solutions with minimal downtime. Our vascular specialists at South Florida Multispecialty Hospital are here to evaluate your symptoms, conduct a personalized vein assessment, and recommend the best treatment for lasting relief.

VLA involves inserting a laser fiber into a diseased vein. The laser heats and collapses the vein, which is then naturally absorbed by the body. Blood reroutes to healthier veins.
RFA uses radiofrequency energy instead of laser light. While both close faulty veins efficiently, RFA may be slightly more comfortable due to lower heat levels.
Patients with symptomatic varicose veins, confirmed saphenous vein reflux, and no significant health contraindications are usually excellent candidates.
Minor side effects include bruising, skin pigmentation, and numbness. Serious risks like DVT are rare when precautions are followed.
Most patients return to normal activity within a day or two. Compression stocking use for 1–2 weeks supports healing.
Yes, if medically necessary. Insurers often cover evaluation and treatment. Out-of-pocket costs vary depending on coverage.
We perform a duplex ultrasound to assess vein anatomy and reflux. This non-invasive test helps determine the best treatment approach.
Clinical studies show high long-term vein closure and symptom improvement. However, new vein issues can develop over time, requiring revaluation.
Yes, both RFA and VLA can be safely repeated if new problematic veins develop.
New laser wavelengths and improved catheters offer greater precision, less post-operative discomfort, and faster recovery.
