Endovenous Radiofrequency Ablation

(VNUS Closure®, ClosureFast™, Venefit™)

What is Endovenous Radiofrequency Ablation?

The VNUS Closure® or RF closure (radiofrequency closure) is a minimally invasive alternative to traditional vein surgery, and is used to treat saphenous, superficial, and varicose veins. Unlike traditional vein surgery, RF closure is performed in our office under local anesthesia.

How does Endovenous Radiofrequency Ablation work?

When the one-way valves in blood vessels are weakened, blood can pool in the veins, enlarging them to the point of becoming varicose veins which can make you feel self-conscious and uncomfortable. These swollen and twisted blood vessels can cause your legs to throb, cramp, and become discolored.

Endovenous radiofrequency ablation uses radiofrequency energy to cauterize and close varicose veins. It is a safe and less invasive procedure than surgery, such as vein stripping, and leaves virtually no scarring. Endovenous radiofrequency ablation is image-guided and burns abnormal veins so they are no longer visible.

Benefits of endovenous radiofrequency ablation treatment include:

  • Less recovery time
  • Quick and convenient procedure
  • Little to no bruising or scarring
  • Minimal swelling post-treatment

During VNUS Closure®, a tiny radiofrequency catheter is inserted into the vein and delivers gentle Radiofrequency energy as it is withdrawn. This heats the vein wall, causing the collagen in the wall to shrink and the vein to close. Once the diseased vein is closed, blood is naturally re-routed to other, healthy veins. In time, the vein will gradually be fully reabsorbed into the surrounding tissue.

Virginia Vein Care is proud to offer the VNUS Closure® procedure for treating varicose veins.

The procedure begins when the diseased vein is accessed via a small puncture under local anesthesia. Next, the small radiofrequency catheter is placed into the vein and guided by ultrasound in the right position. A local anesthetic solution is then placed around the vein and heat is produced through the radiofrequency energy. The heat is applied to the lining of the vein for up to 3 minutes.

Finally, the catheter is removed and the puncture wound is dressed.

How long is the treatment?

Depending on the areas that need to be treated, Endovenous Radiofrequency Ablation closure takes approximately 45 to 60 minutes. The procedure offers a quick recovery and most patients resume normal activities the same day.

Recovering from Endovenous Radiofrequency Ablation

There may be some mild bruising or swelling in the affected area after the procedure. Acetaminophen or ibuprofen can be used for any discomfort. Regular activities can be resumed shortly after the treatment, although any strenuous activity should be avoided for a week.

Patients should wear compression stockings during the day for a week. Your vascular specialist will provide you with more specific post-operative details.

Side Effects

You may experience some post-procedure bruising, redness, swelling, and/or tenderness at the site of the injection. Infection can occur, but precautions are taken to mitigate the risk. There are some reports of thermal (heat) damage to nerves, however it is uncommon and generally goes away in a short period of time. Blood clots formed in the veins can travel to the lungs, but this is also extremely rare, occurring in less than 1% of patients.

Who is a candidate for VNUS Closure®?

The VNUS Closure® system is for anyone with endovascular coagulation of blood vessels in those patients with superficial venous reflux (the backward flow of blood in the veins). It is not recommended for those with a pacemaker or internal defibrillator and patients with a blood clot (a thrombus) in the vein segment which will be treated.
