Radiofrequency ablation (or RFA) is a procedure used to reduce pain. An electrical current produced by a radio wave is used to heat up a small area of nerve tissue, thereby decreasing pain signals from that specific area.
Radiofrequency ablation is a minimally invasive treatment for varicose veins. (Ablation means a doctor uses heat to damage tissue, which makes scar tissue form. This scar tissue closes the vein.) This technique uses radiofrequency energy (instead of laser energy) to heat up and damage the wall inside a vein.
Benefits of RFA treatment.
RFA treats the underlying condition that causes varicose veins and not just the symptoms. And there are a few reasons to consider it:
– It’s safe, proven, does not require hospitalization
– The outpatient procedure time is usually less than an hour
– Recovery time is generally a matter of hours
– Some studies show that the RFA procedure may be associated with lower rates of pain, bruising and complications when compared to other treatment modalities
