摘　　要：目的:系统研究腰交感神经的局部解剖关系。方法:选用128侧腰部交感神经节完整无损的成年尸体,解剖并观察腰部交感神经及其毗邻结构的解剖关系。结果:腰交感神经节数目及位置变异较大,每侧1～6个不等;腰交感干可分裂为2～5支,分裂处多在干的下端,本组共发现12侧发生分裂;腰动脉均位于神经干的深面,腰静脉位于腰交感干浅面者占(68.42±4.35)%,以腰4、5静脉多见;生殖股神经穿出腰大肌平面多数与第2～4腰椎或椎间盘对齐,穿出点距腰大肌内侧缘(0.81±0.48)cm。结论:腰交感神经变异较大,毗邻结构关系复杂,腰交感神经节切除术成功的关键是熟悉腰交感神经的变异及其局部解剖关系。Objective： To study regional anatomy of lumbar sympathetic trunk. Methods： The lumbar sympathetic trunk and its neighboring structures in 128 sides of adult cadavers were observed. Results： The location, shape and number of the sympathetic ganglia were quite variable,and there was 1 to 6 in number unilaterally. Lumbar sympathetic trunk divided into 2 - 3 branches at the distal part were found in 12 sides. Lumbar arteries were all located under the lumbar sympathetic trunk and the lumbar veins, consisting （68. 42±4.35）% situated superficially to the trunk, mainly in L-5 and L-5 veins. Genitofemoral nerve pierced psoas muscle at the level of L2 - L1, or its intervertebral disc （0.81±0.48）cm away from the medial edge of psoas muscle. Conclusion： Because of great variation and complex neighboring anatomic relation of lumbar sympathetic trunk, the critical factor of successful lumbar sympathectomy is familiar with the anatomic relationship of retroperitoneal space.
