Treatment of telangiectasias with a 595-nm pulsed dye laser following hemangioma involution: a retrospective analysis

Telangiectasias are the most frequent type of sequelae of infantile hemangiomas after involution. Few studies have reported the treatment of telangiectasias with 595-nm pulsed dye lasers. Therefore, the objective of this study was to assess the efficacy and safety of a 595-nm pulsed dye laser for treating residual telangiectasias following hemangioma involution. This is a retrospective case series that analyzes the medical records and reviews the charts of 22 patients who had undergone 595-nm pulsed dye laser treatment for residual telangiectasias. Pre- and post-treatment digital images were independently assessed, and the changes were scored to ascertain the efficacy of the treatment (0 = no change, 4 = complete improvement). Of the 22 patients, 59.1% experienced complete resolution of telangiectasias following treatment. No serious complications or side effects were reported. The observations indicate that the 595-nm pulsed dye laser is effective and safe for treating residual telangiectasias following hemangioma involution.
