Under ultrasound guidance the light guide is positioned at v. epigastrica superficialis junction. Under ultrasound guidance tumescent anesthesia is produced around the GSV from puncture site up to the saphenofemoral junction. Laser coagulation (with radial light guide), linear energy density - 75 J/cm, automatic traction of the light guide at the speed 0.7 mm/sec. Varicose veins are resected through skin punctures using Varady hook 1-2 mm."
