RFA is a clinically proven, minimally invasive office-based procedure that treats varicose veins and their underlying cause, venous reflux. RFA uses radiofrequency energy to close off leaky veins in order to eliminate varicose veins. This is a minimally invasive procedure in which a small thin catheter (or flexible tube) is inserted into the affected vein through a small incision. Around the end of the catheter that is inserted there is a small section that uses energy to heat the vein walls through contact. This energy causes collagen in the vein to change shape in order to close the vein. Thereby preventing the backwards flow, and pooling, of blood, which is the cause the varicose vein.
This procedure is completed in less than an hour with minimal or no discomfort. Patients usually return to work or normal activity the same day. Clinical studies have shown outstanding safety, efficacy, and patient satisfaction.
