We assessed the value of intraoperative power Doppler in spinal-cord surgery. Sixteen patients underwent spinal surgery in
which intraoperative power Doppler was used: 4 cases of cervical myelopathy, 3 cases of ossification of the spinal ligament, 5 cases of extramedullary spinal tumor, 3 cases of intramedullary spinal tumor, and 1 case of spinal arteriovenous malformation (AVM). Spinal surgery requires an atraumatic area that is free of bleeding. We used the real-time power Doppler method to
confirmed the anterior spinal artery, central artery, vessels of the subdural space, the feeding artery of spinal tumors, blood
flow around spinal tumors, and the drain of AVM, but the B-mode gray scale Doppler method was unable to confirm them.
Intraoperative power Doppler was found to be helpful, reliable, and safe in spinal surgery.
