    Vascular characteristics of port wine birthmarks as measured by dynamic optical coherence tomography

    Background: Port wine birthmarks (PWB) are congenital capillary malformations. Vessel characteristics, such as diameter and depth, may impact presentation and outcomes. They can be imaged using dynamic optical coherence tomography (D-OCT), a high-resolution, non-invasive imaging method. Purpose: We conducted a cross-sectional observational study to measure in-vivo vascular characteristics as a function of PWB color. Methods: Patients undergoing treatment for PWB were recruited from three sites. PWB were classified by color, and D-OCT images with calculations were obtained. Results: 108 patients were enrolled. Mean age correlated with PWB color, with younger patients having lighter and older patients having darker birthmarks (p ...
