周围神经静脉桥接─—神经断端留有间隙临床应用初步观察

Small gap repair of transected peripheral nerve using venous bridge

我们在动物实验获得成功的研究基础上，在临床上应用了小间隙（２～３ｍｍ）静脉桥接，修复了４２例前臂及腕部神经断裂的病例，２３条正中神经、１９条尺神经。通过术后１５月随访，神经恢复优良率为９３％。术后因肌腱松解第２次手术中证实，在神经小间隙部位神经生长与正常神经外径相同，神经束排列连续性与规律性与正常部位相同。我们认为，根据神经再生过程中的趋向性，为防止神经吻合后神经再生过程中神经束的错对及遗漏，此方法是可行的。同时也为周围神经修复提出了一个新的概念。

AbstractBased on the success in animal experimentation,the authors used venous bridge with small gap of 2～3mm forthe repoir of transected poripherai nerve.In 42 cases oftransectd nerves at the forearm and the wrist,23 weremedian nerves and 20 were ulnar nerves. The follow upporied extended up to 15 months after surgery; excellentrate of functional restoration was93% and the diameter,the continuity of the reconstructed nerve had the same ap-pearance with the normal ones , when observed at a secondoperation for tendolysis.
