What is the difference between VNUS (Venefit Procedure) and EVLT ? Buffalo NY
Both can be used to ablate (or close) the great or lesser saphenous veins. VNUS Closure uses radiofrequency energy to ablate the saphenous vein whereas EVLT uses laser energy to accomplish the same goal. Both catheters are passed via puncture wounds toward the groin. As they are pulled back and out of the vein, they use radiofrequency energy (VNUS Closure) or laser energey (EVLT) to ablate the veins.
