VNUS Closure or radiofrequency ablation is a fairly new type of procedure that is mainly used in the treatment of varicose veins. During VNUS Closure, the doctor inserts a catheter in the affected vein and inserts a liquid anesthetic. Then the heat from the radiofrequency that’s then applied to the damaged vein causes the collagen in the wall of the vein to shrink. This causes the vein to collapse. When this happens, blood is simply shunted to another, healthy vein. The treatment takes around 45 minutes and the patient is made to walk right away to lower the risk of complications like blood clots.
However, the procedure isn’t without its risks. Some patients who have had the VNUS closure performed on them complain that they still have their varicose veins. Other patients complain of bruising, swelling and pain that lingers even days or even weeks after the procedure even when they wear compression stockings. Some patients also feel numbness. Unpleasant side effects are often the result of the doctor who performed the procedure not being properly trained. A patient who wants the treatment should turn to a certified phlebologist (vein specialist) to do it. A phlebologist not only knows how to do the radiofrequency ablation for varicose veins but can use the treatment for other vein problems as well.
The benefits of radiofrequency ablation are the same as traditional vein stripping but with much less risk. Among the benefits are a greatly decreased recovery time. Some patients claim they can go back to work after only a few days of rest, which is quite a difference from traditional vein stripping.
