The lumbar sympathetic ganglia and their surroundings were examined anatomically in 19 human cadavers. The locations of the ganglia on the lumbar vertebral column at the level of the second and third lumbar vertebral bodies were analyzed statistically using a "ganglion score". The ganglia were most frequently found at the level of the lower third of the second lumbar vertebra, at the L2-3 interspace, and at the level of the upper third of the third lumbar vertebra on both the right and left sides. The points at which the sympathetic chain and the lumbar arteries crossed were at the middle third of the vertebral body in both the second and third lumbar vertebra. These results suggest that the most suitable point for placement of the tip of the needle used for chemical lumbar sympathectomy is not the midpoint of a vertebral body, but rather the lower third of the second vertebral body or the upper third of the third vertebral body.
对19具人类尸体的腰交感神经节及其周围组织进行了解剖学检查。使用“神经节评分”对第二和第三腰椎椎体水平的神经节在腰椎柱上的位置进行了统计分析。神经节最常出现在第二腰椎下三分之一水平、L2-3间隙以及第三腰椎上三分之一水平的左右两侧。交感神经链与腰动脉交叉的点在第二和第三腰椎椎体的中三分之一处。这些结果表明，用于化学性腰交感神经切除术的针尖端放置的最合适点不是椎体的中点，而是第二椎体的下三分之一或第三椎体的上三分之一。
