Spinal dural arteriovenous malformations (SDAVMs) were first described in 1977. They present with a progressive paraparesis, principally in men aged 60 years and over. They are usually dorsolumbar in situation and are thought to be acquired lesions which produce symptoms by obstructing the venous drainage of the spinal cord. There are no pathognomonic clinical features and diagnosis depends on a high level of clinical suspicion and myelography extended into the dorsal region. The condition is probably underdiagnosed and may be quite a common cause of progressive leg weakness in elderly people. Surgical treatment is relatively simple, safe, and if carried at an early stage can lead to dramatic neurological recovery. This paper reports nine cases seen over a period of 7 years. All the patients showed marked neurological improvement after surgery.
脊髓硬脊膜动静脉畸形（SDAVMs）于1977年首次被描述。其主要表现为进行性双下肢轻瘫，多见于60岁及以上男性。病变通常位于背腰部，被认为是后天性病变，通过阻塞脊髓静脉引流而产生症状。本病无特征性临床症状，诊断依赖于高度的临床怀疑以及延伸至背部区域的脊髓造影。这种疾病可能诊断不足，可能是老年人进行性腿部无力的常见原因。手术治疗相对简单、安全，若早期进行可使神经功能显著恢复。本文报告了7年间收治的9例病例。所有患者术后神经功能均有明显改善。
