VNUS™ Closure®, also known as the ClosureFast™ Procedure, is an Endovenous Ablative procedure utilizing Radio-Frequency (RF) treatment.  Endovenous ablations can also be performed by Endovenous Lasers.  These laser devices are designed for vein ablations, they are not cosmetic lasers.  Ablative lasers operate in different wavelengths of light and power or wattage behind them.  The lower the wavelength, the more complications and pain occurs. The higher the wavelength, the less pain and black and blue bruising of the treated area occurs. So, it would be important for a laser patient to understand what the doctor uses before making a decision to be treated by that doctor. Center for Venous Disease (CVD) centers utilize the VNUS ClosureFast™ device.

Both technologies treat varicose veins of the Greater Saphenous Vein (GSV) and Small Saphenous Veins (SSV) and are FDA Cleared Medical Devices that are less painful and less invasive than the traditional, barbaric “vein stripping” of years past.  The results shown in several medical studies, as far back as 2002, were that RF technology was less painful, had less post-procedure bruising along the treated area, and did not require post-procedure narcotics.  As the name suggests, VNUS Closure® is a procedure that closes the diseased or damaged vein, usually the Greater or Small Saphenous Vein, so that healthy veins can take over the flow of the blood.  Often times, an Ambulatory Phlebectomy is used in conjunction to, or as an addition with, the VNUS ClosureFast™ procedure.

Several studies have been done to gauge the effectiveness of the VNUS ClosureFast™ procedure (most recent version – 4th generation) and the most recent published data suggests that in as little as two years post-treatment, those that received VNUS ClosureFast™ had a success rate of the treated vein remaining closed and disease free of 90%.3,4,5  

Below in image 1  is the actual VNUS Closure® generator that treats the vein.  The purpose is to treat the vein in segments of 7cm at a time under controlled heat while the generator’s computer monitors the effectiveness of the treatment.  Each 7cm segment of the vein is treated in 1-2, 20 second intervals and then the catheter tip is moved to the next untreated segment.  The entire procedure from beginning to end is roughly 45-60 minutes and is completed in one of CVD’s state-of-the art procedure rooms without the use of General Anesthesia.
