Radio Frequency Ablation (RFA) Treatment

ClosureFast™ Radio Frequency Ablation (RFA)

The ClosureFast™ procedure is a minimally invasive treatment that uses radio frequency (RF) energy to effectively treat patients with varicose veins or chronic venous insufficiency (CVI). The radio frequency energy provides consistent and controlled heat to contract the collagen in the vein walls, causing them to collapse and seal. Once a leg vein is closed, blood flow is redirected to healthy veins.

Who is an Ideal Candidate for RFA?

Many patients with chronic venous insufficiency can be treated with the ClosureFast™ RFA procedure. It is not designed to address spider veins or cosmetic issues. Your vein specialist will review your medical history and your condition to determine if you’re a candidate for this treatment.

The RFA Procedure

A catheter is inserted into the diseased vein through a tiny incision below the knee. Guided by ultrasound imaging, a vein specialist will treat the vein in 7 cm segments for 20 seconds each. The catheter delivers consistent and uniform heat to contract the collagen in the vein walls, causing them to collapse and close. After the vein is sealed shut, blood is then naturally redirected to healthy veins. The treated vein then becomes fibrous tissue and will gradually be absorbed into surrounding tissue.

Benefits of RFA

  • Minimally invasive
  • Safe and effective ultrasound guided procedure
  • Typically uses local anesthesia
  • Reduced recovery time
  • Quick return to normal activity, typically after a few days
  • Most patients report a noticeable improvement in their symptoms within 1-2 weeks
