    Samenvatting

    Endovenous Laser Ablation (EVLA) produces boiling bubbles emerging from pores within the hot fiber tip and traveling over a distal length of about 20 mm before condensing. This evaporation-condensation mechanism makes the vein to act like a heat pipe, where a very efficient heat transport maintains a constant temperature, the saturation temperature of 100 C, over the volume where these non-condensing bubbles exist. During EVLA the above mentioned observations indicate that a venous cylindrical volume with a length of about 20 mm is kept at 100 C. Pullback velocities of a few mm/s then cause at least the upper part of the treated vein wall to remain close to 100 C for a time sufficient to cause irreversible injury. In conclusion, we propose that the mechanism of action of boiling bubbles during EVLA is a heat pipe resembling efficient way of heating of the vein wall.
