颈椎前路手术常用于颈椎椎体病变。然而，颈椎前路手术路线沿线沿着的血管和神经组织结构复杂。目的：测量国人尸体颈长肌、颈交感干和颈交感干神经节的相关数据。共研究了32具成人尸体。我们描绘了CST的外科解剖结构。交感干的上级和下/颈胸神经节一致出现。28.1%的标本可见颈中神经节，其中2例为单侧双颈中神经节。25.0%的标本可见下神经节，其余标本可见颈胸神经节。颈长肌内侧缘间距自上而下逐渐变宽，颈长肌内侧缘间距自下而上逐渐变窄。双侧CST与椎体中线的夹角左侧为11.2°±1.8°，右侧为10.3°±1.4°。两侧颈长肌内侧缘夹角平均为11.1°±1.9°。当LC肌肉被横向切割或严重拖曳时，尤其是在C6和C7水平，CST处于高风险状态。了解CST的区域解剖结构有助于外科医生在颈椎前路手术中识别和保护CST。
Anterior cervical surgery is commonly used for cervical vertebral body lesions. However, the structure of blood vessels and nerve tissues along the route of anterior cervical surgery is complex. We aimed to measure the data of the longus colli, the sympathetic trunk and the cervical sympathetic trunk (CST) ganglia in Chinese cadaver specimens. A total of 32 adult cadavers were studied. We delineated the surgical anatomy of the CST. The superior and inferior/cervicothoracic ganglia of the sympathetic trunk consistently appeared. The middle ganglion was observed in 28.1% of the specimens and there were 2 cases of unilateral double middle cervical ganglia. The inferior ganglion was observed in 25.0% of the specimens and the cervicothoracic ganglion was observed in the remaining specimens. The distance between the CST gradually decreased from the top to the bottom, and the distance between the medial edges of the longus colli gradually broadened from the top down. The average angle between the bilateral CST and the midline of the vertebra was 11.2°±1.8° on the left side and 10.3°±1.4° on the right side. The average angle between the medial margins of longus colli of both sides was 11.1°±1.9°. The CST is at high risk when LC muscle is cut transversely or is dragged heavily, especially at the levels of C6 and C7. Awareness of the regional anatomy of the CST could help surgeons to identify and preserve it during anterior cervical surgeries.
