A 48-year-old man suffered from intractable neck pain irradiating to his right arm. Magnetic resonance imaging (MRI) of the cervical spine was unremarkable. A right-sided diagnostic C6-nerve root blockade was performed. Immediately following this seemingly uneventful procedure he developed a MRI-proven fatal cervical spinal cord infarction. We describe the blood supply of the cervical spinal cord and suggest that this infarction resulted from an impaired perfusion of the major feeding anterior radicular artery of the spinal cord, after local injection of iotrolan, bupivacaine, and triamcinolon-hexacetonide around the C6-nerve root on the right side.
一名48岁男性患有顽固性颈部疼痛，并向右臂放射。颈椎磁共振成像（MRI）未见明显异常。进行了右侧C6神经根诊断性阻滞。在这个看似顺利的操作后，他立即出现了经MRI证实的致命性颈段脊髓梗死。我们描述了颈段脊髓的血液供应，并认为这种梗死是由于在右侧C6神经根周围局部注射碘海醇、布比卡因和曲安奈德-己酸酯后，脊髓主要供血前根动脉灌注受损所致。
