Vertebral artery injury (VAI) is most commonly associated with cervical spine fracture, and many guidelines advocate indiscriminate screening for all cervical spine fractures. The purpose of this study was to determine whether the addition of computed tomographic angiography (CTA) results in a change in management for patients with cervical spine fractures.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods:<\/jats:title>\n                    <jats:p>Adult patients treated for acute cervical spine fractures after blunt trauma during the period of 2000 to 2015 were retrospectively identified. Patients who sustained a penetrating trauma or who had a history of neoplasm or prior cervical spine surgery were excluded. The following variables were recorded: age, biologic sex, race, medical comorbidities, Injury Severity Score (ISS), mechanism of injury, whether CTA of the neck was obtained in addition to computed tomography (CT), cervical spine fracture characteristics and treatment, and the presence of VAI. Recommendation for a change in management with antithrombotic therapy was the primary outcome measure. Detection of stroke and of VAI were secondary outcomes. Propensity-score matching was performed to negate the significant differences in baseline demographic and clinical characteristics.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>A total of 3,943 patients were screened for eligibility, and 2,831 patients met the inclusion criteria. Propensity-score matching yielded 1 cohort who underwent CT + CTA and 1 cohort who underwent CT alone, both with 644 patients and equivalent demographic and clinical characteristics. CTA identified definite or indeterminate VAI in 113 patients, and for 62 patients, antithrombotic therapy was recommended. In the CT-alone cohort, VAI was identified in 11 patients incidentally through other imaging, and antithrombotic therapy was recommended for 8 patients. Two patients in the CT + CTA group had major adverse bleeding events as a result of the initiation of antithrombotic therapy. There were no preventable strokes in either group.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions:<\/jats:title>\n                    <jats:p>The addition of CTA increased detection of VAI and the recommendation for antithrombotic therapy. There were no preventable strokes in either cohort and 2 major adverse bleeding events attributable to the recommended pharmacologic antithrombotic therapy. Nonselective screening is not warranted and should be limited to a high-risk subset of patients.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Level of Evidence:<\/jats:title>\n                    <jats:p>\n                      Therapeutic\n                      <jats:underline>Level III<\/jats:underline>\n                      .
