星状神经节毗邻关系的解剖学研究

目的：观察星状神经节形状、大小、位置及其与周围组织结构的毗邻关系，为临床进行星状神经节阻滞术提供确切的数据支持。方法：用新鲜成人尸体17具，逐层解剖星状神经节周围结构，暴露星状神经节，测量其大小及与周围结构的距离。结果：星状神经节长为（12．3±3．3）mm，宽为（3．9±1．1）mm，厚为（2．1±0．5）mm，神经节下缘距胸膜顶垂直距离为（55．1±1．5）mm，内侧缘距离颈正中线直线距离为（27．1±5．6）mm，星状神经节和椎动脉在冠状面上的最近距离为（7．6±4．8）mm，星状神经节和椎动脉在矢状面上的最近距离为（1．8±2．0）mm。结论：星状神经节周围组织结构复杂，星状神经节阻滞术易误伤周围结构产生并发症。

The Anatomical Study of Stellate Ganglion and Its Adjacency

Objective：To observe the form, size, position of the stellate ganglion （SG）and its surrounding structures, in order to provide accurate data for Clinical technique of the stellate ganglion block. Methods ：The distance from the SG to the surrounding structures were measured on 17 adult cadavers by exposing the SG. Results：Stellate ganglion＇ s length is （ 12.3±3.3）ram, width is （3.9 ± 1.1 ） mm, and thickness is （2.1 ± 0.5 ） ram. Vertical distance from the cupula pleuralis to the lower edge of the ganglion is （ 55.1 ± 1.5 ） mm. Straight distance from medial margin of ganglion to the midline of neck is （ 27.1± 5.6） mm. The shortest distance of stellate ganglion and the vertebral artery in the coronal plane is （7.6 ± 4.8） ram, The shortest distance of stellate ganglion and the vertebral artery in the sagital plane is （ 1.8 ± 2.0） mm. Conclusions ： There are complex structures surrounding the stellate ganglion. It is common to accidentally injure the surrounding structures in stcllate ganglion biock surgery.
