Although pulsed dye laser (PDL) treatment of port-wine stain (PWS) has long been proven safe and effective, incomplete clearance of these vascular malformations can be problematic. In addition, advanced PWS with deeper coloration and tissue hypertrophy can be particularly difficult to treat because of the superficial dermal penetration of 585- to 595-nm light. The purpose of this study was to evaluate the safety and efficacy of a novel device that delivers sequential pulses of 595- and 1,064-nm wavelengths in the treatment of recalcitrant and hypertrophic PWS. Twenty-five children and adults (skin phototypes I-III) with recalcitrant or hypertrophic PWS showing incomplete clearance after 10 prior PDL treatments were included in the study. Successive treatments using a 595-nm PDL and a 1,064-nm neodymium-doped yttrium-aluminum-garnet (Nd:YAG) laser were delivered at 6- to 8-week intervals. Two masked assessors determined clinical improvement of treatment areas using independent evaluation of comparative photographs at baseline and 3 months after treatment using a standard quartile grading scale. The use of dual 595-/1,064-nm wavelengths provided continued improvement of PWS that were previously recalcitrant to ongoing PDL therapy. Side effects were limited to transient erythema, edema, and mild purpura. Rare vesicle formation was observed, with no subsequent scarring or undesirable pigmentary changes. The novel dual 595-nm PDL and 1,064-nm Nd:YAG laser is an effective treatment for PWS that are recalcitrant to PDL therapy alone. The authors have indicated no significant interest with commercial supporters.
