When patients think about varicose vein treatment, "laser" is the first thing that comes to mind. But in modern vascular medicine, laser has a strong rival: radiofrequency ablation (RFA). Multiple studies show RFA achieves the same efficacy as laser with less post-procedure pain and fewer bruises.

What Is RFA for Varicose Veins?

RFA involves inserting a thin catheter inside the diseased vein, which delivers precisely controlled heat via radiofrequency energy (approximately 120°C). This heat causes the vein wall to shrink and seal shut progressively and uniformly along its length.

RFA vs. Laser (EVLA): What's the Difference?

  • Mechanism: RFA = uniform controlled heat / Laser = pulsed light energy
  • Post-procedure Pain: RFA is generally less painful in comparative studies
  • Bruising: RFA causes significantly fewer bruises
  • Efficacy: Nearly identical — both achieve 95%+ closure in Year 1
  • Return to Normal Activity: 1–2 days for both
  • Final Choice: Depends on vein anatomy and surgeon expertise

The RFA Procedure Step by Step

  1. Pre-procedural Duplex Mapping: Ultrasound mapping of the diseased vein
  2. Tumescent Anaesthesia: Injection of dilute local anaesthetic around the vein to protect surrounding tissue
  3. Catheter Insertion: Via a small puncture — no stitches required
  4. Gradual Ablation: The catheter is slowly withdrawn while delivering heat — 30–45 minutes total
  5. Immediate Confirmation: Duplex ultrasound confirms vein closure on the same day

⚠️ RFA Is Not for Every Varicose Vein

RFA is ideal for the great saphenous vein (GSV) and small saphenous vein (SSV). Highly tortuous veins or those with unsuitable diameters may require alternative techniques. The optimal method is determined by the surgeon after detailed duplex assessment.

Who Is a Good Candidate for RFA?

  • Patients with confirmed venous insufficiency on duplex ultrasound
  • Those wanting rapid recovery and same-day return to activity
  • Patients preferring to minimise bruising and post-procedure discomfort

✅ RFA Success Rates

According to European vascular surgery guidelines, RFA achieves closure rates exceeding 95% at one year and 90%+ at five years — matching laser (EVLA) precisely. Both significantly outperform traditional surgery in comfort and recovery time.
