This method for treating the deeper varicose veins of the legs (the saphenous veins) is one of the state-of-the-art breakthroughs in vein medicine. This has replaced surgery for the vast majority of patients with severe varicose veins. This technique is minimally invasive and can be done in a doctor's office.
The doctor puts a very small tube called a catheter into the vein. Once inside, the catheter sends out radiofrequency energy that shrinks and seals the vein wall. Healthy veins around the closed vein restore the normal flow of blood. As this happens, symptoms from the varicose vein improve. Veins on the surface of the skin that are connected to the treated varicose vein will also usually shrink after treatment. When needed, these connected varicose veins can be treated with sclerotherapy or other techniques.
