Radiofrequency ablation, or RFA, is a minimally invasive procedure that uses heat generated by radiofrequency to treat venous insufficiency.
During the procedure a small, specially designed tube (catheter) is inserted into the vein. Ultrasound is used to see inside the vein and carefully position the catheter tip. An electrical current passes painlessly through the catheter and heats the tip to about 120℃. This causes targeted damage to the surrounding vein which will scar and close, allowing the body to naturally redirect blood flow to nearby, healthy veins.
RFA can be performed in an outpatient setting under local anesthesia. Many people feel that it results in less pain and bruising than similar treatments using lasers.
There is no downtime for this procedure. However, you will be asked to wear compression stockings and take short, frequent walks for up to two weeks afterward to aid the healing process.
