摘要 目的 探讨自行研制的高能脉冲CO2 激光器的性能和心肌钻孔血运重建术 (TMLR)对缺血心肌组织血供改善的效果。方法 采用有机玻璃 ,离体猪心和羊急性心肌梗塞模型激光钻孔 ,通过测量孔径 ,孔深 ,病理检查孔道的形态学变化和心肌组织ATP含量的测定 ,分析其间的关系和作用。结果 有机玻璃和离体猪心的实验验证了激光器的汽化穿透效应 ,孔道口径及热损伤情况和仪器的稳定性。羊急性心肌梗塞模型 3组样品ATP含量的测定结果正常对照组 76 16 μmol/g ,TMLR组 6 6 70 1μmol/g ,心肌缺血组 2 9 5 9μmol/g,组间差异显著 (F =16 6 6 2 ,P <0 0 1) ,两组间比较有显著差异 (P <0 0 1,SUK法 )。结论 该仪器的各项技术指标和性能及稳定性符合实验要求。TMLR可以明显改善缺血心肌组织的血供情况。
