为了减少在颈椎前路和前外侧入路交感神经链医源性损伤的风险，外科医生必须明确交感神经链的位置。我们分析了交感神经链及其神经节从C7到进入颅底的过程及其与颈长肌（LC）的关系。用福尔马林固定20具人体尸体，在手术显微镜下解剖。测量了神经节的尺寸，躯干到LC的距离，以及确定链的角度。所有标本均可见上、下颈/颈胸神经节，48%的标本可见颈中神经节。中间神经节由两个神经节组成，占解剖两侧的10%。40%的下颈/颈胸神经节位于C7水平，25%位于C7-Th1椎间盘水平，35%位于Th1水平。仅8%的标本检出椎神经节。交感神经干的路线向内侧收敛，从颈上水平下降到颈下水平。颈椎前路手术入路是一种常用的手术。虽然交感神经损伤引起的Horner综合征在颈椎手术中并不常见，但我们的研究结果支持了目前关于该主题的少数报道，并且对任何在颈椎区域进行手术的外科医生避免这种罕见并发症都是有用的。中国。vol . 22:324-330, 2009。(C) 2009 Wiley-Liss, Inc。
To reduce the risk of iatrogenic injury to sympathetic chain during anterior and anterolateral approaches to the cervical spine, its location has to be well defined and known by surgeons. We analyzed the course of sympathetic chain and its ganglia from C7 up to its entry into the cranial base and its relationship mainly with the longus colli (LC). Formalin fixed 20 human cadavers were dissected under operating microscope. Measurement of the dimensions of the ganglia, distance of the trunk to the LC, and the angles identifying the course of the chain were performed. Superior and inferior cervical/cervicothoracic ganglion were observed in all specimens, the middle cervical ganglion was observed in 48% of the specimens. The middle ganglion consisted of two ganglia in 10% of the dissected sides. Forty percent of the inferior cervical/cervicothoracic ganglion was at the C7 level, 25% was at C7-Th1 disc level, and 35% was at Th1 level. Vertebral ganglion was detected in only 8% of the specimens. The course of the sympathetic trunk converges medially descending from upper cervical levels to the lower levels. Anterior surgical approach to the cervical spine is a commonly used procedure. Although Horner syndrome due to sympathetic injury is not a common sequence of cervical operations, our findings support the current few reports on the subject and should be useful to any surgeon who operates in the cervical region to avoid this uncommon complication.
