Intraoperative CEUS perfusion patterns and arterial resistance predict recovery after cervical myelopathy surgery

Intraoperative contrast-enhanced ultrasound predicted 12-month recovery after laminoplasty for degenerative cervical myelopathy: a visible central spinal artery pattern predicted better recovery than sparse enhancement (P=0.01), and higher arterial resistance index correlated wi…

• Thirty adults with multilevel degenerative cervical myelopathy underwent French-door laminoplasty; mean 12-month recovery rate was 65.81±29.45%.
• Type I perfusion (visible central spinal artery) differed significantly from Type III (diffuse sparse enhancement) for recovery (P=0.01); Type I vs II and II vs III did not reach significance.
• Central spinal artery resistance index was measurable in 21 of 30 patients and was negatively correlated with postoperative modified Japanese Orthopaedic Association score (P=0.03).
