Radiofrequency Ablation Endovenous Radiofrequency Ablation (RFA) is FDA approved, clinically proven, minimally invasive, non-surgical procedure that treats varicose veins on an outpatient basis with minimal discomfort. It is done by inserting a very small tube called a catheter into the vein and delivering RF energy to the vein wall. This causes the vein to shrink, collapse and seal shut. Once it is sealed, healthy veins take over and redirect blood flow back toward the heart. The procedure is endovenous because a varicose vein is thermally ablated from within the vein.The RF procedure can be preformed under local anesthesia and in our office. Most patients return to normal activity within a day.This is a minimally invasive and a gentle alternative procedure to painful vein stripping surgery for varicose veins and superficial venous reflux disease therapy.Insurance eligibility of reimbursement is based on medical necessity, as defined by presence of symptoms. This procedure has one of the broadest and most complete coverage available by insurance.
