Abstract
Objective: To investigate the relationship between dermoscopic vascular pattern and laser efficacy in children with port wine stains. Methods: From January 2023 to December 2023, 43 children aged 3 to 18 years old with port wine stains in our hospital were selected. The Optimex dermoscopy (American Cynosure Company, Model: M393) was used to observe the vascular pattern and clinical efficacy. Results: There were 14 cases (31.11%) of linear blood vessels, 10 cases (22.22%) of dotted blood vessels, eight cases (17.78%) of reticular blood vessels, seven cases (15.56%) of short rod-shaped blood vessels, three cases (6.67%) of mixed-type blood vessels, and three cases (6.67%) of uniform red background pattern. According to the results of dermoscopy, the effective rates of six types of blood vessels, linear blood vessels, dotted blood vessels, reticular blood vessels, short rod-shaped blood vessels, mixed-type blood vessels, and uniform red background pattern were 71.43%, 100%, 62.50%, 100%, 66.67%, and 33.33%, respectively. The difference was statistically significant (P < 0.05). Conclusion: The treatment efficacy of pulsed dye laser on port wine stains varies with different vascular patterns, and the effects on dotted, short rod-shaped, and linear blood vessels are better.
