Radiofrequency ablation is a minimally invasive procedure to treat varicose veins. The procedure involves inserting the catheter into the diseased vein through a very small incision and threading the device through the vessel up to the groin area. Energy from radio waves is used to heat the vessel and seal it to prevent blood from moving in the wrong direction. After the vein is sealed, blood naturally re-routes to healthy veins.
Veins are blood vessels that carry blood back to the heart, working against the force of gravity. Your calf muscles and a system of valves in the veins help move blood toward the heart. With varicose veins, the valves are missing or damaged and do not function properly. This allows blood to remain in the veins, causing them to swell or enlarge. The increased pressure from the blood can lead to pain (including heaviness, aching and burning), mild swelling of the ankles, skin discoloration and may eventually lead to venous ulcers.
