Endovenous Radiofrequency Ablation (VNUS Closure®) Procedure

Catheter inserted in refluxing vein

Catheter positioned, electrodes deployed

RF energy heats and contracts vein wall

Catheter withdrawn, closing vein

Denuded vein is physically narrowed

VNUS Closure

The endovenous radiofrequency ablation (or VNUS Closure) procedure is a minimally-invasive vein treatment used to treat the great saphenous (GSV), small saphenous (SSV) and perforator veins. It uses a patented radiofrequency catheter inserted into the vein, which applies RF energy to heat the vein. This causes the vein to collapse and seal shut. The VNUS Closure procedure has been FDA-approved since 1999 and over 250,000 procedures have been performed worldwide. The VNUS Closure procedure is performed in an office, and under local anesthesia.

Steps of the endovenous radiofrequency ablation procedure are:

  • Physician uses ultrasound to map the course of vein
  • Radiofrequency (Closure) catheter is inserted (through a small puncture) into the vein
  • Local anesthetic solution is ‘infiltrated’ (infused) into the area around the vein
  • Radiofrequency energy is applied to heat the vein and collapse the vein shut
  • Patients usually are asked to walk immediately after the procedure. Walking is encouraged to stimulate reduced pressure on the veins and minimize the risk of complications.
  • Compression stockings are usually prescribed for one to two weeks following the procedure

The endovenous radiofrequency ablation procedure has shown success rates (reflux-free) of 90% with up to 2 year follow-up. Patients are walking after the procedure and generally resume normal activity the same day.

Possible side effects of the Closure procedure include bruising, swelling and numbness, but these are generally only temporary. Endovenous radiofrequency ablation (VNUS Closure) is usually covered by most insurers (e.g., Medicare and private insurers). Eligibility generally requires proof of medical necessity.
