Radiofrequency Ablation Vein Treatment in Minneapolis, MN Area Radiofrequency ablation (RFA or Venefit) is a minimally-invasive procedure that uses heat to treat varicose veins. The heat from the radiofrequency catheter damages the vein walls, which closes the vein. Once the diseased vein is closed, blood is re-routed to other healthy veins. What to Expect RFA is a procedure performed in the clinic, in a sterile setting, under local anesthesia. You can go back to work the same day, with very little downtime. During this procedure, Dr. Afzal inserts a catheter into the vein through a small incision. Heat from the radiofrequency closes the vein as the catheter is slowly pulled out. After the procedure, it is common to experience some bruising or aching in the areas treated. Most patients have minimal discomfort and are able to continue with their daily activities. Less common side effects include local numbness from nerve damage and deep vein blood clots. In our practice the incidence is less than 0.1 percent, which is much lower than the national average.
