To obtain the final result after endovenous laser obliteration it is necessary for the laser energy to reach the venous wall. Using a new in vivo model shows that there are several important mechanisms of effect of laser energy on vein, the most effective of which is its direct absorption by the venous wall in the absence of carbonation. Therefore, for optimum results of the venous ablation at endovenous laser obliteration are preferably used «water-absorbent» lasers (1470 nm) and radial fibers.

Key words: venous wall, laser energy, endovenous laser obliteration.
