popliteal vein in another. Proebstle and colleagues published results for EVLT in 41 limbs with SSV reflux, and found initial success in 95% and no subsequent recanalization in any limb determined by ultrasound surveillance at a median six-month follow-up.25 The single complication reported was a popliteal vein thrombosis that resolved. These results persuade us to favor EVLT for SSV reflux where the vein has been shown to be straight and of diameter greater than an arbitrary 5 mm.
There have been no published reports documenting results after treatment by radiofrequency closure for SSV reflux. It is understood that there was an unacceptable risk of transient sural neuralgia in the early stages and that this has been reduced but not eliminated by perivenous anesthesia.
