Abstract
Capillary malformations, so called port-wine stains (PWS), consist of dysfunctional dilated microvessels in normal dermis. In 1980s, flashlamp-pumped pulsed dye laser (PDL) was introduced to achieve the selective destruction of microvasculature, and PDL has become to be a golden standard method for PWS. Since late 1990s the specifications of PDL was improved and skin cooling devices were developed to avoid the epidermal injuries. In 1999 long-pulsed PDL with adjustable pulse duration (LPPDL) was introduced, and the therapeutic outcome was remarkably improved. However the complete removal of PWS has been challenging. Currently, for the treatment of refractory PWS, the various wavelength laser machines have been applied, and new irradiation techniques have been tried.
We report the laser treatment of PWS from the point of development of laser devices in this article.
