关于本病的病因,有人强调颈椎管狭窄致使颈髓受压,但常缺乏受压的证据;有时见缺血性颈髓病而又没有血管病的显著组织学证据。还有人提出:伴有神经根外膜纤维化的颈髓侧动脉痉挛可能是颈髓缺血的基本病理变化。作者用外科减压治疗1例患者获得良好效果。 On the etiology of this disease, it was emphasized that spinal cord stenosis caused compression of the cervical spinal cord, but often lack of evidence of compression; sometimes see ischemic cervical disease without significant histological evidence of vascular disease. It was also suggested: accompanied by nerve root adventitial fibrosis of the cervical spinal artery spasm may be the basic pathological changes of cervical ischemia. The authors treated with surgical decompression in 1 patient achieved good results.
