Paper Abstract

The cellular response of arterial wall to in vivo exposure to continuous wave argon and xenon chloride Excimer laser irradiation was examined. Acutely, argon irradiation created vaporization of atherosclerotic material with the formation of craters surrounded by zones of thermal and acoustic injury. Thermal and acoustic damage was not noted with the Excimer exposures. Over nine weeks, both types of laser burn demonstrated complete healing. Argon irradiation was associated with damage to normal surrounding tissue which could not be appreciated at the time of laser application.
