This is an abbreviation for RadioFrequency Ablation. It is a common method used for treating varicose veins. As with laser, the saphenous veins are targeted with RFA which are usually the main veins from which varicose veins arise. The procedure is performed usually under local anaesthetic on an operating table. The varicose veins themselves usually require a separate procedure, either to pull them out through separate cuts in the skin or by injecting them with foam. As with laser, RFA works by heating the vein to destruction, but the temperatures are much lower.
