目的 探讨髓内动静脉畸形的治疗方法的选择及对其疗效的评价。方法 回顾性地分析病人的临床资料， 血管影像结构及治疗方法和随访结果。结果 ６４ 例病人中５７ 例接受过栓塞治疗，以微粒栓塞为主（８４％ ）， 其中１０ 例在栓塞后手术， ７ 例单纯手术。治疗后有１４ 例恢复（２１％ ）， ４７例改善（７３％ ）， ８ 例无变化（１２％ ）。５ 例在栓塞后出现并发症， 其中永久性并发症１ 例， 一过性并发症４ 例。结论 髓内ＡＶＭ 的治疗以微粒栓塞为主， 微粒栓塞可使大多数病人的神经功能障碍得以恢复和改善； 其缺点是再通率高。手术治疗可使病人获得解剖治愈， 对于能手术的病人应尽量手术。另外术前栓塞有助于手术操作
Objective To explore the treatment of intramedullary arteriovenous malformations and evaluate its efficacy. Methods Retrospective analysis of the patient’s clinical data, vascular image structure and treatment methods and follow-up results. Results Of the 64 patients, 57 had embolization and were predominantly particulate embolism (84%), of which 10 were performed after embolization and 7 were operated surgically. After treatment 14 cases recovered (21%), 47 cases improved (73%) and 8 cases unchanged (12%). Five cases had complications after embolization, including 1 permanent complication and 4 transient complication. Conclusion The treatment of intramedullary AVM is mainly based on particle embolization. Particle embolization can restore and improve the neurological dysfunction in most patients. The disadvantage is the high recanalization rate. Surgical treatment can make patients get anatomical cure, for surgery patients should be as far as possible surgery. Preoperative embolization also helps with surgical procedures
