Comparison of the results of endovenous laser coagulation (EVLC) using 2-μm radiation and various types of fiber

The results of in-vivo experiments on endovenous laser coagulation (EVLC) using 2-μm radiation and various types of fiber are presented. It was found that the use of a radial fiber with a cylindrical diffuser leads to deeper and irreversible damage to the vein compared to a radial fiber with a circular scattering diagram.
