The immediate effects of endovenous diode 808-nm laser in the greater saphenous vein: Morphologic study and clinical implications

Saphenous ablation using 808-nm laser by variable retraction speed, combined with saphenofemoral interruption, leads to sufficient vein wall injury to assure venous occlusion. Full thickness thermal injury or perforation is infrequent. Optimal results can be obtained in veins <10 mm in diameter.
