分析和总结硬脊膜动静脉瘘的临床诊断及显微手术切除治疗经验。

回顾性分析2010年1月至2014年1月在平煤神马医疗集团总医院确诊并行显微手术切除治疗的硬脊膜动静脉瘘患者8例，并从临床症状、影像学资料及显微手术切除治疗效果总结了临床诊断及治疗的经验。

所有病例均经半椎板入路行动静脉瘘显微手术切除术，术后复查脊髓血管造影，均未发现异常的瘘口及迂曲扩张的引流静脉显影。随访24个月，其中痊愈5例，好转2例，有效率87.5%。

MRI是筛选硬脊膜动静脉瘘的无创手段，脊髓血管造影是确定诊断的金标准。显微手术方法简单，疗效确切，可作为治疗硬脊膜动静脉瘘的首选方法。

To analysis and summary Clinical diagnosis and microsurgical treatment of spinl dural arteriovenous fistula.

8 patients were diagnosed spinl dural arteriovenous fistula (SDAVF) and given microsurgery resection in our hospital from January 2010 to January 2014. we summarized the clinical experience of diagnosis and treatment from the clinical symptoms, imaging data and microsurgery resection treatment effect.

All patients with SDAVF were given arteriovenous fistula microsurgery resection by the approach of semi-lamina. Postoperative spinal angiography showed abnormal fistulas and shadows of gross draining veins disappeared. 24 months of follow-up, 5 cases recovered, 2 cases improved, the effective rate was 87.5%.

MRI is the noninvasive method for SDAVF, spinal angiography is the gold standard for definite diagnosis. The microsurgery method treatment is simple and effective, and it can be used as the preferred method for the treatment of SDAVF.
