脊髓硬脊膜动静脉瘘1例并文献复习

Spinal dural arteriovenous fistula:A case report and literature review

目的探讨脊髓硬脊膜动静脉瘘(spinal dural arteriovenous fistulas,SDAVF)的临床表现、发病机制和影像学特点。方法回顾1例SDAVF患者的诊治过程,并复习相关文献。结果患者为61岁男性,以行走困难为首发症状,随后出现感觉及尿便障碍,脊柱磁共振成像可见条状T2长信号,脊髓血管造影显示L1节段可见脊髓动静脉瘘。结论SDAVF较为罕见,且临床表现不典型,脊髓血管造影是确诊的金标准,确诊后应尽快行手术治疗。

Objective To study the clinical manifestations,pathogenesis and imaging pattern of spinal dural arteriovenous fistula(SDAVF).Methods The diagnosis and treatment of a SDAVF patient was analyzed retrospectively,and the related literature was reviewed.Results The 61-year-old male patient presented mobility limitation as initial symptom,followed by urination and defecation dysfunction,with strip long T2 signal in magnetic resonance imaging and spinal arteriovenous fistula at L1 segment in spinal angiography.Conclusion Although SDAVF is very rare and clinically atypical,spinal angiography is the gold standard for confirmed diagnosis,and surgery should be performed as soon as possible after diagnosis.
