The pathophysiology of cervical spondylotic myelopathy and syringomyelia is incompletely understood. Only 50-60% of the former group of patients and only 30-40% of the latter group of patients show long-term improvement. One possible cause for this might be continued anterior compression of the spinal cord in the former and incomplete drainage of the fluid-filled cavities in the latter. Intraoperative ultrasound imaging can be done in the operating room (4-6, 16-18) and can identify whether an adequate decompression has been done in patients with cervical spondylotic myelopathy and whether there has been complete drainage in shunting of patients with syringomyelia. Intraoperative ultrasound imaging aids the neurosurgeon in checking to see if he did what he set out to do. It is useful in operative procedures for cervical spondylotic myelopathy and syringomyelia.
脊髓型颈椎病和脊髓空洞症的病理生理学尚未完全明确。前一组患者中只有50% - 60%，后一组患者中只有30% - 40%显示出长期改善。造成这种情况的一个可能原因是，前者脊髓持续受到前方压迫，后者充满液体的空洞引流不完全。术中超声成像可在手术室进行（参考文献4 - 6、16 - 18），可确定脊髓型颈椎病患者是否已进行充分减压，以及脊髓空洞症患者分流时是否已完全引流。术中超声成像有助于神经外科医生检查其是否完成了预定操作。它在脊髓型颈椎病和脊髓空洞症的手术过程中很有用。
