ObjectiveVertebral artery injury(VAI)associated with cervical spine trauma has the potential to cause catastrophic vertebrobasilar stroke. However, there are no well-defined treatment recommendations for VAI. The purpose of this study was to identify an effective treatment strategy for VAI following cervical spine trauma.MethodsNinety-seven patients with blunt cervical spine trauma were treated at Hyogo Prefectural Kakogawa Medical Center between January 2013 and September 2017. Of these patients, 49 underwent computed tomographic angiography or magnetic resonance angiography for evaluation of the vertebral artery. Eighteen patients(36.7%)had a diagnosis of VAI. We retrospectively analyzed the clinical features, treatment, and outcomes in these 18 patients.ResultsSeven patients(38.9%)had bilateral VAI, 16(88.9%)had cervical dislocation, and 2(11.1%)had transverse process fractures extending into the transverse foramen. Surgical reduction was performed in 14 patients. Five patients with either bilateral or unilateral occlusion underwent parent artery occlusion before reduction. There were no complications after this procedure. Two patients with bilateral VAI had a stroke before treatment. There were no infarctions in the distribution of the vertebrobasilar artery after intervention. The perioperative stroke rate was relatively good, and almost all Glasgow Outcome Scale scores were related to the degree of spinal cord injury.ConclusionsAggressive screening for VAI is important in patients with cervical spine trauma in order to ensure adequate treatment. Although the treatment strategy described here could yield good results, it may require modification according to the needs of the individual patient.
