Radiofrequency Vein Ablation in Seomyeon, Busan
Radiofrequency vein ablation (RFA) (고주파 정맥 폐쇄술) uses a catheter that delivers controlled radiofrequency heat in short segments to seal a refluxing leg vein from the inside. In Seomyeon, Busan, it is performed under ultrasound guidance and local tumescent anesthesia in about 30–60 minutes per leg. Patients walk immediately, and most resume normal daily activities within a few days.

What is radiofrequency vein ablation?
RFA treats venous reflux by heating the vein wall, causing collagen to contract and the vein to close. Unlike a laser fibre, which emits energy at the tip, many RF catheters heat a fixed length of vein (for example, 7 cm) in timed cycles at a controlled temperature, then are pulled back segment by segment. This controlled heating is associated with relatively mild post-procedure discomfort and bruising.
Who is it for?
- People with symptomatic varicose veins and saphenous reflux confirmed on duplex ultrasound
- Those with swelling, skin discoloration or healed ulcers from venous insufficiency
- Patients preferring a minimally invasive, office-based procedure
It may be unsuitable for very tortuous veins, veins with prior thrombosis that block catheter passage, current DVT, pregnancy or significant arterial disease. Very superficial veins may be better treated with other methods.
What happens at the clinic
- Mapping: duplex ultrasound marks the vein and junctions.
- Access: a small needle puncture is made under local anesthesia, usually near the knee.
- Catheter positioning: the RF catheter is advanced to a safe distance from the deep vein junction.
- Tumescent anesthesia: fluid is injected around the vein for comfort and protection.
- Ablation cycles: each segment is heated for a short cycle, then the catheter is withdrawn.
- Completion: compression is applied; you walk before leaving.
Recovery and aftercare
Walk regularly from day one. Mild tenderness, bruising or a cord-like feeling along the treated vein is common and fades over weeks. Wear compression stockings if advised, avoid long flights or prolonged sitting in the first days when possible, and skip saunas and heavy workouts for about two weeks. Attend the follow-up ultrasound to confirm closure.
Risks and side effects
- Bruising, tenderness and superficial phlebitis
- Temporary numbness or tingling from nearby nerve irritation
- Skin pigmentation along the vein
- Thrombus extension into the deep vein or DVT, uncommon
- Incomplete closure or recurrence needing further treatment
Choosing a clinic for radiofrequency ablation in Seomyeon
- Choose a surgeon who performs and interprets duplex ultrasound for venous disease.
- Ask whether RF, laser or glue is better for your vein anatomy.
- Ask how branch veins will be managed.
- Confirm clot-risk assessment and follow-up imaging.
- Ask about coverage criteria and documentation.
Convenient follow-up
A post-procedure ultrasound within days is common, so a central location helps. Seomyeon is easy to reach on Line 1 or Line 2.
Key facts
- Treats: great and small saphenous vein reflux, some perforator and accessory veins
- Device: RF catheter heating vein segments to a set temperature (e.g., ClosureFast-type systems)
- Anesthesia: local tumescent
- Procedure time: about 30–60 minutes per leg
- Downtime: walking same day; normal activities in a few days
- Aftercare: compression as advised; follow-up duplex ultrasound
- Typical NHI coverage: may apply with documented reflux and symptoms
Frequently asked questions
How does radiofrequency ablation close a vein?
The catheter heats the vein wall to a controlled temperature, causing the wall to shrink and seal. Blood is rerouted through healthy veins, and the closed vein is gradually absorbed by the body.
Is radiofrequency ablation painful?
Local tumescent anesthesia keeps the procedure comfortable for most people. Afterward, mild tenderness and bruising along the vein are common and usually settle within one to two weeks.
How soon can I walk after RFA?
Immediately. Walking is encouraged right after the procedure and throughout recovery to support circulation and reduce clot risk.
Radiofrequency or VenaSeal: which should I choose?
RFA uses heat and requires tumescent anesthesia, often with compression afterward. VenaSeal uses medical glue without heat and often without compression stockings. Both are effective; anatomy, allergy history and coverage influence the choice.
Can varicose veins return after radiofrequency ablation?
The treated vein usually remains closed, but new varicose veins can form over time from other veins. Regular activity, weight management and compression during long periods of standing help.
