A variable-pulse copper vapor laser at 578 nm application for the treatment of facial resistant Port wine stains: case report.

Abstract

Port wine stain (PWS) is presented as a vascular anomaly, light pink to purple in color with various grades of hypertrophy. Facial unilateral upper eyelid and hypertrophic PWS have been reported to be most resistant to pulsed dye laser treatment due to larger vessel diameter and vessel depth.Therefore, it highlights the need for testing new laser modalities for the management of resistant PWS.56-years-old adult II Fitzpatrick phototype female patient, presented with a resistant hypertrophic PWS on the forehead and upper eyelid on the left is presented. Patient was treated with dual-wavelength copper vapor laser (CVL) radiation at 578 nm wavelength. The average power was 0.7-0.8 W with an exposure time of 0.08 -0.2 s.The spot size was1 mm.Patient showed about 75 % lightning of PWS after 2 copper vapor laser treatments. No recurrences were observed during the follow-up period up to 7 years.The variable-pulse copper vapor laser radiation at 578 nm proved to be a minimally invasive, safe and effective treatment for resistant and hypertrophic PWS with a good cosmetic outcome, without side effects (erythema, scarring, depigmentation).
