摘要:

 

端侧神经吻合将神经纤维吸引到受体神经中。在神经束中开窗增强轴突的吸引和髓鞘的形成。文中研究通过端侧吻合分析神经修复的特征,突出轴突萌生的已知机制和启动信号的不同假设(存在或不开窗,雪旺细胞的作用,远端干信号),还指出了实验和临床应用之间的差异。文章提出的观点源于最近的实验和临床经验。
新的技术和材料已经被提出作为端侧吻合的变体,并且期望关于新材料也可以用于导管和基因治疗。最近的研究为了解端侧吻合神经再生机制开辟了新的视角。在这项工作中,开发了用于端侧吻合神经缝合术,以验证轴突再生是否可以诱导来自无吻合部位任何创伤的受损神经生物诱剂。

文章正在进一步研究雪旺细胞的作用和吸引因素,以及刺激,基因转移,生物活性材料和包装保护吻合部位。

Abstract:

Nerve fibers are attracted by sutureless end-to-side nerve coaptation into the recipient nerve. Opening a window in the epineurium enhances axon attraction and myelination. The authors analyze the features of nerve repair by end-to-side coaptation. They highlight the known mechanisms of axon sprouting and different hypotheses of start up signals (presence or absence of an epineurial window, role of Schwann cells, signaling from the distal trunk). The clinical literature is also presented and differences between experimental and clinical applications are pointed out. The authors propose their point of view and perspectives deriving from recent experimental and clinical experiences.

Key words: peripheral nerve repair, nerve coaptation, end-to-side nerve repair, side-to-side nerve repair, epineurial window, Schwann cells, nerve regeneration, nerve babysitter procedures, nerve transfer, nerve graft, glues in nerve repair
