endovenous laser treatment

= EVLT
a minimally invasive procedure to treat varicose veins. A laser fibre (usually an 810-nm diode laser) contained within a sheath is fed up into the vein by ultrasound guidance and slowly withdrawn as it is fired, thereby delivering laser energy that causes irreversible destruction and eventual ablation of the vein.
