In this experimental study, application of endovenous laser shows to be dominated by carbonization at the fibre tip. Although intraluminal laser-induced heat was heterogeneously distributed, with laser tip temperatures up to 1200 degrees C, heat dissipation was minimal. Continuous exposure of laser light appears to be better suited in EVLA than intermittent.

In this study, no significant difference was demonstrated in late outcome after EVLA or cryostripping in patients with great saphenous varicose veins.

EVLT is a feasible, safe, and fast procedure for eliminating GSV reflux and has excellent cosmetic results. Despite the learning curve, we believe that the treatment results are promising. When successful treatment is achieved by EVLT, a prospective follow-up of 2 years demonstrates durable results.
