The progress in percutaneous transluminal laser angioplasty (PTLA) over the past two years is presented. The technical development includes the application of new equipments to laser sources, delivery systems and monitors. We review new experimental research in rapidly establishing animal models and human postmortem specimens, as well as efforts to select adequate wave length and irradiation time for laser energy with suitable infusion media. A summary of clinical trials is given on expanding usage, complication rates and long-term patency of PTLA. The current trends in PTLA respecting guide wire assisted balloon angioplasty and other recanalization methods are described.
本文介绍了经皮腔内激光血管成形术（PTLA）在过去两年中的进展。技术发展包括将新设备应用于激光源、输送系统和监测器。我们回顾了在快速建立动物模型和人类尸检标本方面的新实验研究，以及为选择合适的波长、照射时间以及合适的输注介质来输送激光能量所做的努力。文中给出了关于PTLA扩大应用、并发症发生率和长期通畅率的临床试验总结。还描述了PTLA相对于导丝辅助球囊血管成形术和其他再通方法的当前趋势。
