Endovenous laser treatment: is there a clinical difference between using a 1500 nm and a 980 nm diode laser? A multicenter randomised clinical trial.

Aim: We compared the use of two different laser wavelengths in the treatment of great saphenous vein (GSV) reflux: the 1500 nm versus the 980 nm diode laser. We studied the occlusion rates and noted possible side-effects.

Methods: In three centers 180 great saphenous veins were treated with endovenous laser ablation (EVLA).
