Radiofrequency Thermal Ablation (RF)-VNUS Closure


Typical Treatment Benefits

  • Reduction or elimination of leg pain, achiness and fatigue caused by venous reflux translates to renewed enjoyment of activities such as walking, running and bicycling — results will vary by patient
  • Improved healing of venous ulcers and skin changes related to venous reflux
  • Your legs will look better

This YouTube video describes superficial venous reflux disease and the VNUS Closure Procedure using Radiofrequency Thermal Ablation (RF)

Basic Patient Information About This Treatment
Radiofrequency Thermal Ablation (RF) is typically used to treat varicose veins, and not spider veins. This outpatient procedure has been in use for over 10 years, and has consistently seen excellent results. As with our other non-surgical procedures, most of our patients find themselves ready to resume normal activity almost immediately. Patients report feeling little if any pain during the procedure. Typically, patients receive a local or regional anesthetic to numb the treatment area.

What RF Does
Via a small, narrow tube (catheter), tiny bursts of energy are used to heat the diseased vein wall forcing its collapse. As a result basically two things happen:
1) The blood flow gets redirected to healthier veins;
2) Symptoms of venous reflux such as the blue, bulging varicose vein, leg pain, swelling and fatigue can be reduced or eliminated.

Considerations and Follow-up
The doctor will have you wear a compression stocking for a couple of weeks, and may suggest a regimen of regular exercise. Some patients may experience minor bruising that goes away quickly. By comparison to stripping and other surgical techniques, those possible side-effects are minimal. Results will vary by patient, and in some cases multiple treatments maybe needed to achieve the desired results. Dr. Forman carefully works with each patient to develop a plan best-suited to their specific needs. Visit the Expectations and Results Section to see example before-and-after photos.

The VNUS Closure procedure is a minimally invasive treatment alternative with less pain and less bruising when compared to traditional vein stripping surgery and laser treatment. Using the Closure system, physicians close the diseased veins by inserting the Closure catheter into a vein and heating the vein wall using temperature-controlled RF energy. Heating the vein wall causes collagen in the wall to shrink and the vein to close. After the vein is sealed shut, blood then naturally reroutes to healthy veins.

Frequently Asked Questions About Radiofrequency Ablation-Venous Closure Procedure

The Closure procedure is a minimally invasive treatment for superficial venous reflux. A thin catheter is inserted into the vein through a small opening. The catheter delivers radiofrequency (RF) energy to the vein wall, causing it to heat, collapse, and seal shut.

Since valves can't be repaired, the only alternative is to re-route blood flow through healthy veins. Traditionally, this has been done by surgically removing (stripping) the troublesome vein from your leg. The Closure procedure provides a less invasive alternative to vein stripping by simply closing the problem vein instead. Once the diseased vein is closed, other healthy veins take over and empty blood from your legs.

During a stripping procedure, the surgeon makes an incision in your groin and ties off the vein, after which a stripper tool is threaded through the saphenous vein and used to pull the vein out of your leg through a second incision just above your calf.

In the Closure procedure, there is no need for groin surgery. Instead, the vein remains in place and is closed using a special (Closure) catheter inserted through a small puncture. This may eliminate the bruising and pain often associated with vein stripping (i.e., that may result from the tearing of side branch veins while the saphenous vein is pulled out). Vein stripping is usually performed in an operating room, under a general anesthetic, while the Closure procedure is performed on an outpatient basis, typically using local or regional anesthesia.

Three randomized trials of the Closure procedure vs. vein stripping, including the most recent multi-center comparative trial, show very similar results. In the multi-center comparative trial, the Closure procedure was superior to vein stripping in every statistically significant outcome. In the study, 80.5% of patients treated with the Closure procedure returned to normal activities within one day, versus 46.9% of patients who underwent vein stripping. Also, Closure patients returned to work 7.7 days sooner than surgical patients. Patients treated with the Closure procedure had less postoperative pain, less bruising, faster recovery and fewer overall adverse events.1

The Closure procedure takes approximately 45-60 minutes, though patients normally spend 2-3 hours at the medical facility due to normal pre- and post-treatment procedures.

Patients report feeling little, if any, pain during the Closure procedure. Your physician will give you a local or regional anesthetic to numb the treatment area.

The Closure procedure can be performed under local, regional, or general anesthesia.

Many patients can resume normal activities immediately.2 For a few weeks following the treatment, your doctor may recommend a regular walking regimen and suggest you refrain from very strenuous activities (heavy lifting, for example) or prolonged periods of standing.

Most patients report a noticeable improvement in their symptoms within 1-2 weeks following the procedure.

Patients report minimal to no scarring, bruising, or swelling following the Closure procedure.

As with any medical intervention, potential risks and complications exist with the Closure procedure. All patients should consult their doctors to determine if their conditions present any special risks. Your physician will review potential complications of the Closure procedure at the consultation, and can be reviewed in the safety summary. Potential complications can include: vessel perforation, thrombosis, pulmonary embolism, phlebitis, hematoma, infection, paresthesia (numbness or tingling) and/or skin burn.

Only a physician call tell you if the Closure procedure is a viable option for your vein problem. Experience has shown that many patients with superficial venous reflux disease can be treated with the Closure procedure.
