Paper Abstract

The presently most promising treatment modality for port wine stains is selective photothermolysis. This technique is based on exposure of the lesion to yellow laser light of high energy density and long pulse-length, typically 5 - 10 J/cm2 and 0.5 ms, respectively. Although promising clinical results have been reported, only a small percentage of the patients obtains full fading of their lesions. This might in part be due to the fact that most clinicians treat port wine stains with rather standardized settings of the laser parameters. However, clinical response can, hopefully, be improved if these setting are adjusted to each individual lesion. This paper gives a brief discussion of the importance of parameters such as depth, diameter and vessel wall thickness, together with a presentation of non-invasive methods for determination of these values.
