Radiofrequency Ablation for Varicose Veins: Procedure, Recovery, and Outcomes

Radiofrequency ablation (RFA) is a minimally invasive, catheter-based treatment for symptomatic varicose veins caused by great or small saphenous vein reflux.

Procedure Steps

1. Preparation: Standing ultrasound mapping; local anesthesia (tumescent) along vein tract.
2. Access: Ultrasound-guided puncture, usually at knee/calf (GSV) or ankle (SSV).
3. Catheter placement: RFA catheter (e.g., ClosureFast) advanced to saphenofemoral/saphenopopliteal junction.
4. Ablation: 120°C thermal energy delivered in 7-cm segments (20 sec each) with pullback; tumescent fluid protects surrounding tissue.
5. Confirmation: Ultrasound verifies vein closure.
6. Compression: Gradient stocking (20–30 mmHg) for 1–2 weeks.

Outcomes & Recovery

• Technical success: >95% initial occlusion.
• 1-year closure: 90–97%.
• Symptom relief: Significant improvement in VCSS, AVVQ scores.
• Recovery: Outpatient; ambulate immediately; return to work 1–3 days; avoid strenuous exercise 1–2 weeks.
• Complications: EHIT (endovenous heat-induced thrombosis) <2%, paresthesia, skin burns, DVT <1%, phlebitis.

Comparison

RFA vs. EVLA (laser): similar efficacy; RFA may have less post-op pain/bruising. Both superior to stripping for QoL and recovery.
