How Does RFA Work?
During the procedure, the vein doctor administers local anesthesia and makes a small incision on the skin’s surface. The incision is an entry point for a hollow needle (catheter) that’s driven into the diseased vein under ultrasound guidance. Once lodged in place, the vein physician delivers tumescent anesthesia to insulate the surrounding tissues against the thermal energy, thus ensuring optimal comfort.
Finally, the vein doctor activates the catheter to generate thermal energy and collapse the diseased vein, rerouting the accumulated blood into healthier leg veins. This restores optimal blood circulation to the heart, and the diseased vein is eventually reabsorbed by the body. Radiofrequency ablation concludes within 30 minutes and involves no downtime.
The procedure has a 98% success rate, and it’s usually covered by medical insurance, especially if you have the signs and symptoms of vein disease.
