Radiofrequency Ablation
Radiofrequency Ablation (RFA) is a minimally invasive medical procedure used to treat varicose veins. It involves the use of heat generated by radiofrequency energy to close off faulty veins, primarily those in the legs. During the procedure, a thin catheter is inserted into the affected vein through a small incision. The catheter emits radiofrequency energy, which heats the vein walls, causing them to collapse and seal shut. This redirects blood flow to healthier veins, improving circulation. The treated vein is eventually absorbed by the body over time.
- Radiofrequency ablation (RFA) is a less invasive way of treating varicose veins compared to stripping and is associated with fewer complications.
- There are no long cuts in the legs, which allows for a quick recovery and an early return to work.
- RFA is well tolerated by patients, and produces good cosmetic results.
- RFA is done under local anaesthetic.
- You can walk following treatment and recovery is typically short.
- Complications from the procedure are rare but may include minor skin irritation, a feeling of numbness or prickling in the treated area or tender lumpy areas where the vein is healing. This is usually temporary and resolves within weeks.
Radiofrequency Ablation Process:
- The catheter is inserted into the vein using local anaesthetic, under ultrasound control.
- The catheter is surrounded in more local (tumescent) anaesthesia.
- The catheter is activated, sequentially heating (cauterising) and sealing the vein.
