Endovenous Radiofrequency Ablation (RFA)

Endovenous radiofrequency ablation (RFA) is a minimally invasive procedure used to treat varicose veins and chronic venous insufficiency. It works by delivering controlled radiofrequency energy through a thin catheter inside the affected vein. This heat closes off the faulty vein, rerouting blood into healthy veins.

How Will I Know if I Need RFA?

You may be a candidate for RFA if you experience:

  • Varicose veins
  • Swelling in the legs or ankles
  • Pain, cramping, or heaviness in the legs
  • Skin discoloration or irritation
  • Venous ulcers that are slow to heal

A vein specialist will evaluate your symptoms and use ultrasound imaging to confirm whether RFA is appropriate.

How does RFA Work?

RFA is performed in-office under local anesthesia and typically takes less than an hour. The procedure involves:

  • Using ultrasound guidance to place a thin catheter into the diseased vein
  • Delivering radiofrequency energy to heat and close the vein
  • Allowing blood flow to naturally reroute to healthier veins

After the procedure, patients are encouraged to walk and resume most normal activities the same day.

Which Treatment Option is Best for You?

Treatments such as radiofrequency ablation, VenaSeal, Varathena, or Sclerotherapy can close off damaged veins and redirect blood to healthier veins.

Surgical Options 

In more severe cases, ambulatory phlebectomies or other surgical procedures may be recommended.
