Laser treatment of vascular skin lesions is rapidly improving. Port wine stain (PWS) is one of the first lesions successfully treated with laser. The pulsed dye laser (PDL) has been developed on the concept of selective photothermolysis and has revolutionized PWS treatment. Even though the response is variable, substantial blanching can be obtained after several sessions. Greater selectivity and better response have been achieved by modifying PDL parameters such as longer pulse width, longer wavelength, or higher energy fluencies with cooling skin devices. It is known that thick, deep or raised lesions present poor response to conventional treatments. The aim of this study is to review the different lasers and other light sources which are developing for the treatment of PWS and other vascular lesions.

El tratamiento con láser de lesiones vasculares cutáneas está avanzando rápidamente en los últimos años. La mancha en vino de Oporto (Port wine stain [PWS]) es una de las primeras lesiones tratadas con láser con éxito. El láser de colorante pulsado (PDL) se ha desarrollado basándose en el concepto de la fototermólisis selectiva y ha supuesto una revolución en el tratamiento de PWS. Sin embargo, la respuesta obtenida es variable, alcanzándose un aclaramiento sustancial del color de la lesión tras varias sesiones. Diversos estudios demuestran que la modificación de parámetros del PDL como el aumento en la amplitud de pulso, mayor longitud de onda, o fluencias más altas asociadas a un sistema de enfriamiento, consiguen un aumento en la selectividad y mejoran la respuesta. Por otra parte, lesiones profundas, gruesas o sobreelevadas responden pobremente a los tratamientos convencionales. El objetivo de nuestro estudio es la revisión de los distintos tipos de láser así como otras fuentes de luz que se están desarrollando para el tratamiento de éstas y otras lesiones vasculares
