星状神经节的应用解剖及其与Horner综合征关系的探讨

The applied anatomy of stellate ganglion and it's relationship with Horner's syndrome

目的:探讨星状神经节局部解剖及其损伤与Horner综合征的关系。方法:在31具成人尸体标本上,观测了60侧星状神经节的大小、形态、分支及其与肋骨的毗邻关系。结果:星状神经节长径(20.8±3.1)mm,宽径(8.5±1.9)mm,完全融合的出现率是60.0%(36/60)。神经节下缘低于第2肋骨上缘的出现率是33.3%(20/60),星状神经节与第1脊神经的交通纤维进出神经链的位置点均高于2肋上缘,两者距离为2.3～7.8mm。结论:第2肋骨上缘水平损伤交感神经链可能伤及部分星状神经节,但不会引起Horner综合征中的眼部症状。

Objective： To explore the local anatomy of stellate ganglion （SG） and relationship of its injury with the occurrence of Homer＇s syndrome. Methods： 31 adult cadavers with 60 sides SGs available were studied, The examine index included the size and the morphological characteristics of SG, including its relative position with the adjacent ribs. Results： Average size of SG was （20.8±3.1）mm×（8.5±1.9）mm. the fusion rate was 60.0% （36/60）. In 20 sides （ 33.3% ）, the lower border of SG was lower than the upper border of the second rib. Rami from T1 spine nerve entered SG above the upper border of the second rib in all cases, the average distance between the site where rami from T1 spine nerve entering SG and the upper border of the second rib was 2.3 7.8mm.Conclusions： Injury of the sympathetic trunk at the level of the upper border of the second rib will probably damage the lower portion of SG, but will not induce any optic symptoms comprised in Homer＇s syndrome.
