Treating Veins With Radiofrequency Ablation

Most people with symptomatic varicose veins or chronic venous insufficiency are candidates for radiofrequency ablation. Exceptions include patients with active bleeding disorders, active infection at the treatment site, or certain pregnancy stages. Your vein specialist will review your medical history and perform a diagnostic ultrasound before recommending RFA as part of your personalized treatment plan.

During radiofrequency ablation, a thin catheter is inserted into the diseased vein under ultrasound guidance. Once positioned, the catheter delivers controlled thermal energy to heat the vein wall, sealing the vein permanently. Blood flow is naturally rerouted to healthier veins in the leg, and the treated vein is gradually reabsorbed by the body over several months, along with the appearance of the surface varicose veins it caused.

Radiofrequency ablation is generally described as mildly uncomfortable rather than painful. A local anesthetic is used to numb the treatment area, and a tumescent solution is delivered around the vein for additional numbing and to protect surrounding tissue. Most patients report only minor pressure or warmth during the procedure and can return to work the same day.

Both radiofrequency ablation and endovenous laser treatment (EVLT) are minimally invasive endovenous procedures that seal diseased veins from the inside. RFA uses radiofrequency energy, reaching a maximum temperature of about 120°C, while EVLT uses laser light, which can exceed 1,200°C at the fiber tip. RFA typically causes less bruising and post-procedure discomfort than EVLT, though both are highly effective. Your vein specialist will recommend the best option based on the size, location, and characteristics of your veins.

There is zero-downtime after radiofrequency ablation. Most patients return to work and normal daily activities the same day. You will be asked to wear medical-grade compression stockings for several days and to walk regularly to promote healthy circulation. Strenuous exercise, hot baths, and long-haul travel should be avoided for one to two weeks. Most patients see improvement in symptoms such as leg heaviness, swelling, and aching within a few weeks.

Radiofrequency ablation is covered by most major medical insurance plans when it is medically necessary — for example, to treat symptomatic varicose veins or chronic venous insufficiency. Our verifications team can confirm your coverage before your appointment.
