目的：探讨单纯内镜下微血管减压术治疗原发性三叉神经痛的方法及临床价值。方法回顾性分析采用单纯神经内镜下微血管减压术治疗35例原发性三叉神经痛的临床资料，并对其疼痛缓解程度、手术时间和术后并发症发生率进行评估分析。结果术中35例均在内镜下发现责任血管，平均手术时间为85．6 min；术后疼痛完全消失33例，疼痛较术前明显缓解2例，并发症发生率为2．8％；随访期间，无死亡及复发病例。结论神经内镜能够单独完成三叉神经微血管减压术，可消除传统显微镜下手术的视野盲区，不易损伤血管、神经，明显减小对正常脑组织牵拉和损伤。故单纯内镜下微血管减压术可作为传统微血管减压术或神经内镜辅助微血管减压术的替代手术，有临床推广价值。“,”Objective To explore the operative technique and clinical value of simple endoscopic vascular decompres-sion (EVD)for trigeminal neuralgia.Methods Clinical data of 35 cases of primary trigeminal neuralgia treated with simple EVD during Nov.2013 and Sept.2014 were retrospectively reviewed.Pain relief,operation time and postopera-tive complications were analyzed.Results Of all patients,33 achieved immediate postoperative pain control and 2 obtained obvious pain relief.Mean operation time was 85.6 minutes and the complication rate was 2.8%.No death or recurrence were detected during follow-up.Conclusion Neuroendoscopy can complete trigeminal microvascular decompression alone,eliminate the blind area in traditional microscopic surgery,and significantly reduce the injury to blood vessels,nerves and brain tissues.Endoscopic vascular decompression is a safe and effective alternative for tradi-tional microvascular decompression or neuroendoscopy-assisted microvascular decompression.
