In 2000, Mark Whiteley and Judy Holdstock of The Whiteley Clinic wanted to get away from treating perforating veins by using a 2 cm incision under general anaesthetic and putting clips on the perforating veins via a special endoscope - a technique called SEPS (Sub-Fascial Endoscopic Perforating vein Surgery). Although this was considered very modern at that time, it was keyhole surgery rather than the new pinhole surgery that we were wanting to achieve.
Mark Whiteley and Judy Holdstock found that, by using the ultrasound, they were able to get needles into the perforating veins with great accuracy. They started pushing VNUS Closure® catheters into the perforating veins and using the same electrodes to heat the wall and permanently close the perforating veins - in effect, a mini VNUS Closure® of these veins.
They called their new technique TRLOP, Trans-Luminal Occlusion of Perforators.
After several years, the success of this technique was the same as the previous keyhole technique and so the VNUS Company produced a special catheter called the RFS (radio-frequency stilette) catheter, specifically for this purpose.
The Whiteley Clinic are currently producing their five year results, showing that closure of perforators using the RFS device is equivalent in success to the other available techniques, using general anaesthetic or more invasive techniques.
