Long-pulsed 1,064-nm high-energy dye laser improves resistant port wine stains: 20 report cases

Excerpt

Port wine stain (PWS) is one of the vascular birthmarks, which is commonly seen in the clinic. It is present at birth of the patients and grows commensurately [1]. The pulsed dynamic laser (PDL), which is based on selective photothermolysis, is now regarded as the first-line treatment for PWS [2]. The concept of selective photothermolysis with the 585- and 595-nm PDL revolutionized the treatment of PWS, and most of PWS can be significantly lightened with the 595-nm PDL [3‐5]. However, few PWS obtained complete recovery and nearly 20 to 30 % of them hardly lighten at all with PDL treatment [6]. In our cosmetic dermatology center, 595-nm PDL-resistant PWS were documented since the last 6 years. In order to improve the treatment efficacy of the resistant PWS, we employed a new promising modality, long-pulsed yttrium–aluminum–garnet (YAG) 1,064-nm PDL, for the treatment of 595-nm PDL-resistant PWS. The aim of this study was to assess the role of the long-pulsed, 1,064-nm high-energy PDL in the treatment of resistant PWS. …
