lu-august-editors-choiceWausau, WI (August 7, 2019) – Although lasers are the treatment of choice for port wine stains (PWS), some PWS are laser-resistant. PWS blood vessels that have high blood flow, large diameters, and are located deeply in the skin are difficult to treat with lasers. To guide a tailored laser protocol, this study used in vivo reflectance confocal microscopy (RCM) to characterize the general morphological features of laser-resistant PWS blood vessels, e.g. blood flow, density, diameter, and depth.

The clinical report of this study, published in Lasers in Surgery and Medicine (LSM), the official journal of the American Society for Laser Medicine and Surgery, Inc. (ASLMS), was selected as the August 2019 Editor’s Choice.

The study, led by Jianyun Lu, MD, PhD is titled “Characterization of LaserResistant Port Wine Stain Blood Vessels Using In Vivo Reflectance Confocal Microscopy.”  

“This study aims to investigate the morphological features of laser-resistant port wine stain blood vessels using non-invasive reflectance confocal microscopy, which will guide a tailored laser protocol to target these blood vessels,” said Lu.

The study concluded RCM can be a valuable tool for a prognostic evaluation on laser‐resistant lesions before treatment, thus guiding tailored laser treatment protocols to improve therapeutic outcomes.
