目的 :结合 3例硬脑膜动静脉瘘 (IDAVF)伴脊髓表面引流的影像学、临床表现、病程特点 ,探讨引起脊髓症状的原因。方法 :分析 3例IDAVF伴脊髓表面引流的影像学特点、临床表现、病程发展 ,结合文献加以分析和讨论。结果 :临床症状主要表现为颅内症状者 1例 ,脊髓症状者 2例。结论 :IDAVF伴脊髓表面引流的临床表现与脊髓根静脉的引流出路有关。硬脑膜动静脉瘘伴脊髓症状的诊断较困难 ,特别是仅有脊髓症状者。年轻人中慢性脊髓病变 ,急性加重时应注意颅内血管造影可做出诊断
OBJECTIVE: To investigate the imaging, clinical manifestations, and course of disease in 3 cases of dural arteriovenous fistula (IDAVF) with spinal drainage. Methods: The imaging features, clinical manifestation and course of development of three cases of IDAVF with spinal drainage were analyzed and discussed in combination with the literature. Results: Clinical symptoms mainly manifested as intracranial symptoms in 1 case, spinal cord symptoms in 2 cases. Conclusion: The clinical manifestations of IDAVF with spinal cord surface drainage are related to the drainage of the root canal of spinal cord. Dural arteriovenous fistula with the diagnosis of spinal cord more difficult, especially those who only spinal cord symptoms. Chronic spinal cord disease in young people, acute exacerbations should pay attention to intracranial angiography can make a diagnosis
