The principle of the Radiofrequency technique is to burn and retract the varicose vein using an alternating electric current. The technique requires the use of a specific generator to which is connected a dedicated and single-use endovascular probe to apply the current in contact with the varicose wall. The probe, or catheter, is introduced into the vein to the saphenofemoral junction (in the groin). The probe delivers thermal energy at 120 ° which causes a retraction of the walls of the veins. The procedure is performed on an outpatient basis, under local anesthesia. The entire procedure is carried out under echo-guidance. Tumescence anesthesia is also used for this technique.
Post-operative follow-up is usually accompanied by little or no pain. The patient can walk again right after the procedure. A compression by band is put in place at the level of the treated leg and the wearing of stockings is then strongly recommended for 15 days. A postoperative visit is scheduled 7 to 10 days after the procedure.
