Venous reflux disease can cause discomfort, swelling and varicose veins in your legs, it's superficial, and approximately 25 million Americans suffer from venous reflux. There a procedure called VNUS Closure Fast that is minimally invasive and can treat venous reflux disease. VNUS Closure Fast Procedure This procedure utilizes heat to permanently close the problem vein. With VNUS Closure FAST a catheter is threaded into the vein near the knee, through a very small (2mm to 3 mm) incision. Ultrasound is then used to correctly position the catheter in the vein. Before the catheter is turned on, local anesthesia is injected around the vein.

The catheter heats up  6.5 centimeters of the vein for about 20 seconds, then it's moved along the length of the vein. The VNUS Closure FAST closes and scars the vein, which is then treated as waste by the body and is removed over time. Some parts of the treated varicose vein may remain in bulging sections and a few smaller veins may remain after treatment. These remaining veins can later be treated with sclerotherapy (injections which also close smaller veins) or laser treatment. Because this treatment is minimally invasive, and performed with only local anesthesia, patients are back on their feet the next day. Improvements will be noticed in about one week, with the body taking several months to remove the scarred vein.
