What Is Radiofrequency Ablation (RFA)?
Radiofrequency ablation is a minimally invasive procedure where:
- A thin catheter is inserted into the affected vein
- Radiofrequency energy (heat) is used to close the vein
- Blood flow is redirected to healthier veins
How Does RFA Work?
Step-by-Step Overview
1. Preparation
- Local anesthesia is administered
- Ultrasound is used to guide the procedure
2. Catheter Placement
- A small tube (catheter) is inserted into the vein
3. Heat Application
- Radiofrequency energy heats the vein walls
- The vein collapses and seals shut
4. Natural Healing
- The body gradually absorbs the closed vein
- Blood circulation improves through normal veins
Benefits of Radiofrequency Ablation
1. Minimally Invasive
- No major cuts or stitches
- Small puncture site
2. Less Pain and Discomfort
- Compared to traditional vein surgery
3. Quick Procedure
- Typically completed within 30–60 minutes
4. Faster Recovery
- Resume daily activities within a few days
5. High Success Rate
- Effective in relieving symptoms and improving appearance
