Saline is then slowly infused into the vein from the tip of the catheter to further create a near-bloodless field inside the vein, allowing the catheter to preferentially heat the vein wall, rather than the blood. Noninvasive ultrasound is used to confirm the catheter tip position and the physician then activates the RF generator, causing the electrodes at the tip of the catheter to heat the vein wall to a target temperature of typically 85 degrees Centigrade or degrees Fahrenheit. As the vein wall is heated, the vein shrinks and the catheter is gradually withdrawn.
During catheter pullback, which typically occurs over 15 to 18 minutes, the RF generator regularly adjusts the power level to maintain target temperature to effectively shrink collagen in the vein wall and close the vein over an extended length. Confirm Closing of Vein. After treatment, ultrasound imaging is used to confirm closing of the vein. If a portion of the vein is not closed, the catheter can be reinserted and energy reapplied.
After the procedure, the narrowed vein gradually becomes fibrous, sealing the interior of the vein walls and naturally redirecting blood flow to healthy veins. Experienced physicians often complete the procedure in 45 to 60 minutes. Patients who undergo the Closure procedure typically resume normal activities within a day. Closure Procedure Highlights Relief of symptoms Outpatient procedure Resume activities typically within a day Good cosmetic outcome with minimal or no scarring, bruising, or swelling As with any medical intervention, potential risks and complications exist with the Closure procedure.

Varicose Veins more info. Heart Disease Treatment more info. Heart Attack more info. Venous reflux can cause blood to pool in your legs and lead to symptoms such as pain, swelling, itching, and varicose veins. The VNUS Closure procedure, an alternative treatment option to traditional vein stripping surgery, brings state-of-the-art technology to an age old disease. The procedure is an outpatient treatment. Local anesthesia is used to numb the treatment area.
You will receive pre-op pain medications and anti-anxiety drugs 30 minutes before the procedure. The vein is accessed percutaneously and a small incision is performed. The catheter delivers radiofrequency RF energy to the vein wall, causing it to heat, collapse and seal shut. Once the diseased vein is closed, other healthy veins take over and empty blood from your legs. As normal return flow is reestablished, your symptoms should improve considerably.
Following the procedure, the catheter is removed and a band-aid is placed over the insertion site. You should refrain from long periods of standing immediately following the procedure to help speed your recovery. Many patients resume normal activities within days. Patients who undergo VNUS Closure report feeling some pain and burning during the administration of the local anesthesia prior to the procedure.
After the local is given, during the Closure procedure, the patient may experience some heat. During the stripping procedure, the surgeon makes an incision in your groin and ties off the veins, 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. In the Closure procedure, there is no need for stripping; instead, the vein remains in place and is closed using a special Closure catheter inserted through a small incision.
This minimizes the bruising and pain often associated with vein stripping i. Vein stripping is usually performed in an operating room, under general anesthetic, while the Closure procedure is typically performed using local anesthesia. For a few weeks following the treatment, you should being a regular walking regimen and refrain from very strenuous activities heavy lifting, for example or prolonged periods of standing. Most patients report noticeable improvement in their symptoms in the weeks following the VNUS Closure procedure.
Patients report minimal scarring, bruising or swelling following the Closure procedure. Most of this is seen in the first weeks, if at all. Some numbness may be experienced at the groin level and medial thigh and knee. This usually resolves. It may take months.
