Abstract
BACKGROUND The majority of port-wine stain (PWS) patients treated with the pulsed dye laser (PDL) do not achieve complete blanching. Safe administration of higher fluences has been proposed as a means of improving treatment efficacy. OBJECTIVE To determine the safety and efficacy of PWS treatment with the 1.5-msec PDL at high fluences in conjunction with cryogen spray cooling. METHODS Twenty PWS patients were treated with the PDL in combination with cryogen spray cooling utilizing a 7 or 10 mm spot size and fluences ranging from 6 to 15 J/cm2. Before and after treatment photographs were compared on a blinded basis. RESULTS No scarring or skin textural changes occurred. Blanching scores were as follows: 20% of patients achieved 75% or greater blanching after an average of 3.3 treatments, 30% achieved 50–74% blanching, 20% achieved 25–49% blanching, and 30% achieved less than 25% blanching. CONCLUSION In conjunction with cryogen spray cooling, the PDL can be safely used at high fluences. At this time it is not clear that the use of higher fluences improves treatment efficacy; however, as other aspects of PWS laser treatment are optimized, safe administration of higher fluences is likely to be advantageous.

Title Treatment of port-wine stain birthmarks using the 1.5-msec pulsed dye laser at high fluences in conjunction with cryogen spray cooling
All of the port-wine stain (PWS) were on the face, neck, Table 1
This study clearly demonstrates that treatment of PWS with pulsed dye laser (PDL) in conjunction with cryogen spray cooling is safe at high incident light doses

Treatment of Port-Wine Stain Birthmarks Using the 1.5-msec Pulsed Dye Laser at High Fluences in Conjunction with Cryogen Spray Cooling. PORT-WINE STAINS (PWSs) are congenital, vascular malformations of the skin found in approximately 0.3% of children.[1] PWSs may be located anywhere on the body, but are commonly found on the face and neck, where they may have serious psychological consequences.[2,3,4] Patients are often perceived by others as “marked,” which may adversely affect personality development Over time, these lesions may hypertrophy and patients may experience local bleeding. Patients and their families often seek treatment
