- W873669088 abstract "目前临床用于心肌血运重建术的激光主要有CO2和Ho∶YAG激光,它们也有各自的优缺点,寻找新的能有效形成激光孔道且对周围组织损伤小的激光源是目前研究的一个方向,为此,我们比较国产KTP倍频Nd∶YAG激光和Ho∶YAG激光对离体猪心激光打孔的组织学效应,探讨KTP倍频Nd∶YAG激光用于激光心肌血运重建术的可能性.方法: 分别用 KTP倍频Nd∶YAG激光和Ho∶YAG激光以多种级别的工作参数对离体猪心左心室心内膜面进行照射,进行病理组织学检查,测量激光孔道直径、深度及坏死层厚度,比较两种激光心肌打孔的组织学变化.结果: KTP倍频Nd∶YAG激光和 Ho∶YAG激光均能有效形成激光孔道,随能量增加,孔道深度增加.KTP倍频Nd∶YAG激光具有孔道直、热损伤小的优点.结论:KTP倍频Nd∶YAG激光是激光心肌血运重建术可供选择的激光源.(OF2)" @default.
