Popis: Much recent interest has been directed toward the application of laser energy in the vasculature for vaporization of atherosclerotic obstruction. The Nd:YAG and the argon lasers are the only ones applicable to currently available fiberoptic delivery systems, but the argon laser is ineffective in the Ablation of calcified atherosclerotic plaque. 1 The Nd:YAG laser, although effective in the ablation of calcified plaque, has been of limited value because of its high tissue penetration and consequent deep coagulation necrosis. 2 The introduction of a contact mode of delivery of 3 of Nd:YAG laser energy may minimize this problem; this investigation was undertaken to investigate the effect and healing of conventional non-contact delivery of Nd:YAG laser energy in the vasculature and to compare it to the new contact system.
