Radiofrequency ablation (RFA) is the process of using focused radiofrequency waves to remove living tissue with heat,  killing problematic cells in the process. Doctors use it to treat a wide range of medical conditions. Since the FDA approved Venefit (formerly known as VNUS Closure Procedure) in 1999, RFA has become a standard treatment for enlarged leg veins (such as varicose veins). The procedure usually takes between 45 minutes to an hour to perform, and your doctor can perform it in the office or an ambulatory surgery setting using localized anesthesia.

Before beginning your radiofrequency ablation procedure, your doctor will use ultrasound to map out the veins to be worked on. With clear direction from the ultrasound, your doctor will make a small incision or puncture near the knee and then thread a small catheter into the vein to be treated. Localized tumescent anesthesia (saline-infused anesthesia) will be injected into the vein to numb the area, firm up the area, and make it easier for the doctor to perform the ablation. When the entire vein to be treated has been canalized (fully threaded with the catheter), sound waves will be applied to heat and collapse the vein in segments, beginning from the top down as the catheter is pulled back and out of the vein through the incision. The collapsed vein will close (occlude) and scar up, and eventually it will be reabsorbed into the body. Your body will redirect the flow of blood away from the occluded vein and through healthier venous pathways.

Compression is vital to the healing process after any venous treatment. Compression reduces bruising, encourages circulation and reduces the risk of blood clots after a venous procedure. After your radiofrequency ablation procedure, your treated leg will be wrapped in compression bandages or stockings. Often your doctor will wrap your untreated leg as well. Your doctor will recommend that you wear compression stockings for a week or two following the procedure. You will be encouraged to walk immediately after the surgery, and you will be discouraged from bed rest and heavy lifting. You will most likely be able to resume normal daily activities within a day or two following the procedure. Be sure to schedule a follow-up appointment within three to seven days so your doctor can monitor your healing process and check for any complications.

Possible complications of radiofrequency ablation are temporary bruising, swelling and numbness. Skin burns are rare under the care of an experienced vein specialist. Sometimes patients are allergic to the anesthesia administered during the procedure. Patients report slightly less pain and bruising following radiofrequency ablation treatment than those who receive endovenous treatment. 

Many insurance companies cover radiofrequency ablation with the same stipulations they would for any surgical procedure. Eligibility for radiofrequency ablation is usually determined by the extent of your varicose veins and your medical need.
