Paper Abstract

Effective removal of Port Wine Stain vasculature requires two mechanisms: coagulation of the blood and denaturation of the vessel wall and the surrounding dermis. In this way recanalisation of the old vascular network is prevented and substitution by a normal vessel matrix can occur. A theoretical model was developed to calculate the optiirtuin laser parameters to achieve this. A Monte-Carlo based optical niodel describes the distribution of the laser energy after scattering processes. This distribution is then used by a twodimensional thernial model to predict the temperatures achieved both within the vessel and in the peri-vascular dernds. The predicted effects of various power densities and pulsewidths for 577nit and 585nm will be presented.
