摘要目的 开展单一切口下的腓浅神经与腓骨短肌联合活体组织检查,通过回顾相关病例的临床和病理资料,分析联合活体组织检查的诊断意义.方法 共15例患者,女性7例,男性8例,年龄14 ～72岁,其中亚急性6例、慢性9例,均患有周围神经病,3例临床上合并肌肉病.周围神经病的临床类型包括对称性感觉和运动性神经病7例、多发性单神经病5例、对称性感觉性神经病3例.在外踝前上方纵切口,取材腓浅神经与腓骨短肌.神经和肌肉病理结论的意义评价分为3级:(1)具有确诊意义；(2)对诊断有帮助:(3)对诊断无帮助.结果 活体组织检查病理结论有确诊意义者7例,包括血管炎5例、炎性脱髓鞘性周围神经病1例和淀粉样变性1例.有帮助者5例:病理改变分别为:慢性髓鞘性神经病伴洋葱球样肥大纤维；小血管病变伴轻度炎性反应；轻度间质炎性反应；脂褐素沉积等.无帮助者3例.最终12例通过活体组织检查得以确诊.结论 联合活体组织检查的诊断阳性率较高,血管炎周围神经病和淀粉样变性等适用联合活体组织检查.

abstractsObjective In an attempt to clarify the usefulness of combined nerve and muscle biopsy in the diagnosis of neuromuscular disease when compared with traditional sural nerve biopsy.Methods Fifteen biopsies of superficial peroneal nerve (SPN) and peroneus brevis muscle ( PBM ) by one incision performed within one neurological clinic were reviewed.All patients had peripheral neuropathy while 3 of them had myopathy clinically.The diagnostic significance of SPN and PBM biopsies were classified into 3 grade: essential,helpful,no value.Results Of 15 SPN and PBM biopsies,7 showed essential pathological findings which reached the etiological diagnosis, including 5 definite vasculitis, 1 inflammatory demyelinating polyneuropathy and 1 amyloid neuropathy.Five biopsies are helpful for etiological diagnosis,including demyelinating neuropathy,mild inflammation,and microvascular lesion,et al.Three biopsies are of no value for etiological diagnosis which only have nonspecific change such as type 2 fiber atrophy,neurogenic atrophy and axonal degeneration et al. Finally,SPN and PBM biopsies made the definite etiological diagnosis possible in 12 patients.Conclusions SPN and PBM biopsy improved the yield of specific pathological and etiological diagnosis of neuropathy and myopathy such as vasculitis and amyloidosis with minor trauma and side effect.Further clinical and pathological studies will be necessary for a better practice of combined nerve and muscle biopsy.
