1. What is the Radiofrequency Ablation of Varicose Vein?
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.
