ELANA, excimer laser-assisted nonocclusive anastomosis, is a technique using an excimer laser/catheter system for intracranial bypass surgery of the brain. The technique has been developed over the past 12 years by Tulleken and colleagues at UMC Utrecht in The Netherlands for treatment of primarily untreatable giant aneurysms. We review here the emergence of transplanted conduit bypass as a valuable technique for managing these lesions and the subsequent development of ELANA bypass. The ELANA technique allows the operating surgeon to perform an extracranial-to-intracranial or intracranial-to-intracranial bypass using a transplanted large caliber conduit without occlusion of the recipient artery, thus eliminating intraoperative ischemic insult related to temporary occlusion time. We describe the ELANA technique, illustrate it with intraoperative photos, and review the relevant literature. ELANA is shown to be safe; we discuss its advantages over conventional techniques.
ELANA，即准分子激光辅助非闭塞性吻合术，是一种使用准分子激光/导管系统进行脑部颅内搭桥手术的技术。该技术由荷兰乌得勒支大学医学中心的图勒肯及其同事在过去12年中研发，主要用于治疗原本无法治疗的巨大动脉瘤。我们在此回顾移植管道搭桥术作为一种治疗这些病变的有价值技术的出现，以及随后ELANA搭桥术的发展。ELANA技术使手术医生能够使用移植的大口径管道进行颅外至颅内或颅内至颅内的搭桥，而无需闭塞受体动脉，从而消除了与临时闭塞时间相关的术中缺血性损伤。我们描述ELANA技术，用术中照片进行说明，并回顾相关文献。结果表明ELANA是安全的；我们还讨论了它相对于传统技术的优势。
