RFA a minimally invasive treatment alternative to the traditional vein stripping surgery for varicose veins and gives better cosmetic results with less scarring. The principle is that by removing the abnormal vein by applying radiofrequency energy inside the vein (‘endovenous’) to destroy (‘ablate’) it.
2. How is RFA done?
The procedure is performed on an outpatient basis with the patient awake. The entire procedure is done under ultrasound visualisation. After a local anaesthetic is injected into the thigh area, the laser fibre is threaded into the vein through a small puncture hole. Then radiofrequency energy is released which heats up the wall of vein and causes it to collapse. Radiofrequency energy is released continuously as the fibre moves along the whole length of the diseased vein, resulting in the collapse and ablation of the varicose vein. Following the procedure, a bandage is placed over the entry site, and additional compression is applied. Patients are then encouraged to walk and resume all normal activities
3. How is RFA of varicose vein different from conventional surgery?
RFA does not require general anaesthesia and is a less invasive procedure than vein stripping. The recovery period is also shorter than surgery. Patients usually have less post-operative pain, less bruising, faster recovery, fewer overall complications and smaller scars.
