Perimedullary arteriovenous fistula (AVF) is a relatively rare spinal vascular malformation. Although it has traditionally been considered to be a congenital lesion, some cases identified in adults have suggested that the lesion may be acquired. The etiology and exact mechanism of these lesions are unknown. The authors present a case of a perimedullary AVF caused by a direct stabbing injury of the spinal cord and induced by subsequent kyphosis, and they discuss the pathogenesis and treatment strategy.
硬脊膜动静脉瘘（AVF）是一种相对罕见的脊髓血管畸形。尽管传统上认为它是一种先天性病变，但一些在成年人中发现的病例表明该病变可能是后天获得的。这些病变的病因和确切机制尚不清楚。作者报告了一例由脊髓直接刺伤引起、随后发生后凸畸形导致的硬脊膜动静脉瘘，并讨论了其发病机制和治疗策略。
