Endovenous laser ablation of the great saphenous vein comparing 1920-nm and 1470-nm diode laser.

Background: The aim of this study was to compare venous occlusion rates at a one-year follow-up comparing 1920-nm versus 1470-nm endolaser.

Methods: Randomized prospective study with consecutive patients with varicose veins associated to great saphenous reflux. The 1470-nm laser ablation was performed in continuous mode, with power of 10 W, while for the 1920-nm it was set in 5 W.
