A retrospective analysis of 440 port wine stains patients treated with 595 nm pulsed dye laser
Abstract：Objective To evaluate the efficacy of 595 nm pulsed dye laser(PDL) in the treatment of port wine stains(PWS),and to analyze the efficacy differences of PDL in different groups of PWS patients.Methods A retrospective analysis of 440 patients with PWS who had been treated by 595 nm PDL were carried out.The 440 patients were classified into different groups according to the age,type of lesion,area of lesion and times of treatment.Based on the evaluation of dermatologists before and after the treatment,the therapeutic effects were judged as recovery,excellence,effectiveness,and invalid.Then the influence of the aforementioned factors on the curative effect was analyzed by statistical methods,and the adverse reactions and complications were recorded.Results The total response rate was 83.41％ for all the patients.Clinical efficacy of the PDL was correlated with patients' age,lesion types,lesion areas and treatment times.The curative effect was better for the patients with smaller age and smaller lesion area,and the incidence of adverse reaction was lower.Conclusion The 595 nm PDL was safe for PWS patients and had satisfactory clinical effect.However,the rate of recovery was low,and a minority of patients showed resistance to PDL treatment.
