Modeling Laser Treatment of Portwine Stains: Fact or Fiction?

摘要

AbstractModeling laser treatment of portwine stains (PWS) is shown to be possible (a) when information is available about the anatomy and physiology of the PWS vasculature, (b) when coagulation of a vessel can be defined in terms of physics, (c) when we know what size vessels at what dermal depths require coagulation, (d) when the optical properties of the skin constituents are known, and (e) when the light distribution following laser irradiation can be deduced from those optical properties. This report focuses on physical criteria for vessel coagulation, and relates the consequences of two criteria with recent experimental and clinical results.
