%X BACKGROUND: A dural arteriovenous fistula (dAVF) involving the vertebral artery (VA) is a rare vascular pathology that can result from damage to the VA, most frequently following cervical spine trauma. In most traumatic cases, the dAVF develops and manifests shortly after trauma.
METHODS: A patient was admitted after a fall from the stairs causing neck pain. Computed tomography of the cervical spine revealed a Hangman's fracture, and angiography showed a left VA dissection. The patient was treated with a cervical brace and clopidogrel. Three weeks after trauma, the patient was admitted because of bilateral leg ataxia, dizziness, and neck pain. Repeat imaging revealed increased displacement of the cervical fracture and a dAVF from the left VA with retrograde filling of the dAVF from the right VA. Embolization of the dAVF using coils proximally and distally to the dAVF was performed prior to placing a halo brace. At 6 months, all symptoms had disappeared and union of the cervical spine fracture had occurred.
CONCLUSIONS: This case report emphasizes the need for follow-up angiography after traumatic VA injury resulting from cervical spine fracture and underlines important treatment considerations for successful obliteration of a dAVF of the VA.
