Pulsed Dye Laser at Subpurpuric Settings for the Treatment of Pulsed Dye Laser-Induced Ecchymoses in Patients With Port-Wine Stains.
Dermatologic Surgery : Official Publication for American Society for Dermatologic Surgery [et Al.] 2018 Februrary
BACKGROUND: Post-procedure purpura is a major complaint of patients with port-wine stains (PWSs) treated with pulsed dye laser (PDL).
OBJECTIVE: To assess the safety and efficacy of using PDL at nonpurpuric settings to treat ecchymoses that develop within PWSs after treatment with PDL.
MATERIALS AND METHODS: Prospective, randomized, controlled study using 595-nm PDL for treatment of PWSs and laser-induced ecchymoses. Port-wine stains were treated in entirety at baseline. Two days later, ecchymoses on randomly selected half of the lesion were re-treated with PDL at subpurpuric settings. Treatment series was repeated 4 to 8 weeks later, and follow-up was at 1 month. Reduction in bruising and PWS clearance were assessed. Three masked evaluators graded clinical improvement using a 4-point scale (1 = 1%-25% improvement, 2 = 26%-50% improvement, 3 = 51%-75% improvement, and 4 = 76%-100% improvement).
RESULTS: Twenty adults with 21 PWSs on the head, trunk, and extremities were treated. After first treatment, reduction of bruising was graded a mean value of 2.43 for the treatment side, compared with 1.93 for the control side (p = .012); after the second treatment, 2.83 compared with 2.40 (p = .021). No significant adverse events occurred.
CONCLUSION: Pulsed dye laser can be used safely and effectively to reduce treatment-induced purpura in patients with PWSs.
