Abstract
Background: Angiogenesis has a crucial role in the pathogenesis and the maintenance of psoriasis. Dilated tortuous blood vessels can be acted upon by vascular lasers according to the principle of Anderson and Parrish.
Objective: The goal of this study was to evaluate the efficacy of the sequential application of pulsed dye laser (PDL) with Nd: YAG laser in the treatment of plaque psoriasis.
Design: This was a prospective clinical trial with a three-month follow-up.
Patients and Methods: Thirty three patients with chronic and stable plaque type psoriasis were included in this study. Patients received 7 sequential PDL + Nd: YAG laser treatments at two weeks intervals.
Intervention: Intervention included the application of seven sequential PDL and Nd: YAG laser treatments at two weeks intervals.
Outcome Assessment: Evaluation of clinical improvement by examination and photography.
Results: All patients showed a significant decrease in modified Psoriasis Area and Severity Index (m PASI) score.
Conclusion: Combined PDL + Nd: YAG presents a new therapeutic option for the treatment of plaque psoriasis.
