title: Treatment of port wine stains using the pulsed-dye laser at 585 nm with the dynamic cooling device.
abstract: Port wine stains (PWS) are common vascular malformations appearing more frequently on the face and neck. One of the most prevalent treatment modalities for PWS is the pulsed-dye laser (PDL). The first generation PDL was limited to a 450 microseconds pulse width which was inadequate for the treatment of larger caliber vessels. Second generation PDLs have pulsed widths approximately three times longer (1.5 ms). This, along with the dynamic cooling device (DCD), which allows the safe use of higher fluences, should result in more clinical improvement in the treatment of PWS that were previously resistant or minimally responsive to first generation PDL treatment. We report a case of a 29-year-old white male with extensive PWS on the left face, left neck, and back, which displayed only mild changes with the first generation PDL. However, the use of the 1.5 ms PDL at 585 nm at high fluences in conjunction with the DCD resulted in marked improvement of the patient's PWS.
