title: Treatment of port-wine stains with the flashlamp-pumped pulsed dye laser: extended clinical experience in children and adults.
abstract: Seventy-six patients (51 females, 25 males) with port-wine stains (PWS) were treated with the flashlamp-pumped pulsed dye laser (585 nm, 450 microseconds). The patients ranged in age from 1 month to 71 years (average, 14 yr). Forty-nine percent of all patients under study had a 90% or better (average, 94.6%) lightening response after an average of 9.0 (range, 4-15) laser treatment. Overall, there was a 79% clinical improvement seen after an average of 9.1 (range, 2-19) laser treatments. In contrast to previous studies, the number of treatments necessary to obtain PWS clearing in older children (9-15 yr) and adults (> 16 yr) was not significantly greater than the number required to treat PWS in infants (0-2 yr) and younger children (3-8 yr). In fact, PWS in children aged 3 to 8 years required the greatest number of laser treatments, which may be due to continued abnormal growth of the ectatic blood vessels comprising the lesion during the growth of the child. In addition, there did not appear to be a significant difference in the number of laser treatments necessary to obtain clearing of PWS in different body locations. While the 585 nm pulsed dye laser continues to be the treatment of choice for removal of PWS in children and adults, the number of treatments necessary to obtain lesional clearing in all age groups in greater than previously reported.
