It treats the underlying source for varicose veins. After the vein is sealed, blood naturally re-routes to healthy veins.
The Medtronic-Covidien ClosureFast Procedure (previously VNUS™ procedure) is a minimally invasive treatment for varicose veins and Chronic Venous Insufficiency (CVI) in which our vein specialist inserts a Covidien ClosureFast™ endovenous radiofrequency ablation (RFA) catheter to collapse and close enlarged incompetent truncal leg veins. The ClosureFast™ catheter is inserted into the truncal vein through a tiny puncture around the knee. Guided by ultrasound imaging vein cold tumescent local anesthesia is installed around the vein After that the physician treats a 7 cm segment of vein with a 20-second burst of radiofrequency coil heating, causing the vessel to shrink around the catheter. The physician withdraws the catheter, treating each segment until the entire length of the vein has been sealed. An average 45 cm length vein can be treated in this manner in just three to five minutes. Total procedure time is around 15 - 30 minutes per leg. Sedation is usually not needed except in anxious patients on request
The catheter delivers uniform, consistent heat to each segment and temperatures do not exceed 120° C. As a result, the VNUS™ ClosureFast Procedure causes minimal bruising and allows for rapid patient relief and almost painless recovery. The procedure performed in an out-patient setting. You leave the clinic within 15-30 minutes after the procedure. Compression stockings are described for 24-48 hours.
The long term results (> 95 % success) are well confirmed
