High-Fluence Modified Pulsed Dye Laser Photocoagulation With Dynamic Cooling of Port-wine Stains in Infancy

Arch Dermatol. 2000;136(7):942-943. doi:

Lightening or partial clearing of port-wine stains (PWS) in infants has been demonstrated through photocoagulation with the pulsed dye laser (PDL) (wavelength, 585 nm; pulse width, 0.45 milliseconds; spot size, 5-10 mm ; energy fluences, 4-8 J/cm2).1,2 It has been theorized that selective vascular injury could be further optimized by modifying the PDL to include a broader pulse width, a longer wavelength, and higher energy fluences through the use of dynamic cooling spray.35 In this pilot study we used a PDL with modified parameters in the treatment of infants with facial PWS to evaluate the safety and efficacy of this new device.
