Radio-frequency ablation is a technique for shutting down a vein with venous reflux. Venous reflux leads to the development of varicose veins (learn more about ablations here).
RFA uses microwave energy to heat the vein wall, causing the vein to shut down. The procedure takes about 30-40 minutes, depending on whether a microphlebectomy is performed.
The procedure is completely outpatient. You walk in, have the procedure done, walk out, and you are back to your normal activities that day. There are no incisions, stitches, or scarring. You will need to wear a compression stocking for about a week, and you will need some Motrin or Advil for a few days afterwards.
