Time interval between pulse dye laser treatments of port-wine stains: 30 years of experience

ABSTRACT

Port-wine stains (PWS) are frequently refractory to laser treatments. The aim of this study is to evaluate the role of treatment interval time. From 1990, 216 patients underwent Pulsed Dye Laser sessions. The laser sessions were scheduled at a minimum interval of 4 weeks to a maximum of 48 weeks. Clinical outcomes were assessed 8 weeks after the last laser session. Better results were obtained with 8 weeks interval time between therapy session, and high efficacies were also found for intervals of 4, 6 and 10 weeks. For greater interval instead, the effectiveness is significantly lower.
