Abstract

We report histological changes in port-wine stains treated with illumination times of 3.3 ms (5 W) and 17 - 26 ms (2 W). A copper vapor laser is used and the spot diameter is 0.4 mm. The results show that using an illumination time of 3.3 ms there is more damage to the endothelial cells of the vessel walls and less damage to non vascular tissue. This is in agreement with the predictions of theoretical calculations.
