UNASSIGNED: OBJECT Approximately 10% of @entity1 with blunt traumatic @entity130 have a complete occlusion of the vertebral artery (VA). @entity385 due to embolization of @entity715 from an occluded VA following cervical spine surgery has been observed. The risk of @entity385 with cervical spine surgery in the presence of an occluded VA, however, has never been determined. METHODS A retrospective chart review of 52 @entity1 with a @entity432 following a @entity130 was performed. Clinical and radiographic characteristics were collected and analyzed. RESULTS Ten @entity1 (19.2%) suffered an @entity385 attributable to a traumatic @entity432 . Univariate analysis demonstrated that @entity1 with @entity385 were significantly older (p = 0.042) and had a lower rate of cervical spine surgery (p < 0.005). Multivariate analysis found cervical spine surgery to be protective against @entity385 (OR 0.049 [95% CI 0.014-0.167], p = 0.014); increasing age and bilateral @entity1317 (bilateral occlusion or unilateral occlusion with contralateral dissection) were risk factors for @entity385 (OR 1.05 [95% CI1.02-1.07], p = 0.065 and OR 13.2 [95% CI 2.98-58.9], p = 0.084, respectively). CONCLUSIONS Traumatic @entity432 is associated with a risk of @entity385 and mortality. Corrective cervical spine surgery potentially decreases the risk of @entity385 by stabilizing the spine and thereby reducing motion across the occluded segment of the VA and preventing embolization of @entity715 . While a high stoke risk may be @entity66 , novel therapies should be investigated.
