Vertebral artery peak systolic velocity (PSV) was assessed preoperatively and at 1, 3, 6, and 12 months postoperatively using duplex ultrasonography. Functional outcomes were measured with the Visual Analog Scale for neck and arm pain, the Neck Disability Index, and patient-reported dizziness. Radiographic fusion was confirmed at serial follow-up.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>\n                      PSV decreased significantly, indicating improved vertebral artery flow: right side from 48.85 \u00b1 12.71 to 39.0 \u00b1 7.45 and left side from 48.20 \u00b1 12.02 to 41.54 \u00b1 7.56 (both\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      &lt; 0.001).
