摘　　要：目的:探讨胸腰椎区域硬脊膜动静脉瘘(Spinal dural arteriovenous fistula, SDAVF)的发病机制、临床表现和治疗。方法:回顾1例胸椎区域SDAVF患者的诊治过程并进行文献回顾。结果:患者为55岁男性,以腰痛伴左下肢麻木为首发症状,随后出现行走困难,脊柱MRI的T2加权序列中显示脊髓高信号和髓周空流血管影,脊髓血管造影术确诊胸椎区域硬脊膜动静脉瘘。结论:SDAVF较为罕见,误诊率较高,晚期诊断容易使患者预后恶化,因此,及早的诊断与干预变得尤为关键。Objective: To investigate the pathogenesis, clinical manifestations, and treatment of spinal dural arteriovenous fistula (SDAVF) in the thoracolumbar region. Method: A retrospective review of the diagnosis and treatment process of a patient with thoracic spinal dural arteriovenous fistula (SDAVF) and a literature review. Results: The patient, a 55-year-old male, presented with initial symptoms of lower back pain accompanied by numbness in the left lower limb, followed by walking difficulties. In the T2-weighted sequence of the spinal MRI, high signal intensity in the spinal cord and a vascular flow void around the spinal cord were observed. The diagnosis of spinal dural arteriovenous fistula in the thoracic region was confirmed by spinal cord vascular angiography. Conclusion: SDAVF is relatively rare, with a high misdiagnosis rate. Late diagnosis can easily lead to worsening prognosis for patients. Therefore, early diagnosis and intervention are particularly critical.
