For Patients

Thermal ablation of varicose veins

What is Radiofrequency therapy?

Radiofrequency (RF) therapy is a minimally invasive alternative to traditional vein stripping. It’s done by inserting a very small tube called a catheter into the vein and delivering radiofrequency energy to the vein wall. This causes the vein to shrink, collapse and seal shut. Once it’s sealed, healthy veins take over. The radiofrequency procedure can be performed under local anesthesia. Patients have reported little, if any, pain during the procedure, and most return to normal activity within a day. Some common side effects include temporary tenderness and numbness. You can expect a noticeable improvement within 1 to 2 weeks, with good cosmetic outcomes and little to no scarring.  The procedure is often supplemented by sclerotherapy to clear up any residual veins.
