化学性腰交感神经节切除的应用解剖研究

APPLIED ANATOMIC STUDY FOR OPTIMAL SITE OF CHEMICAL LUMBAR SYMPATHECTOMY

在21具成人尸体标本中，解剖了腰交感神经节及其周边解剖结构，在腰2～3椎体范围内，应用“神经节记分”方法，测量了神经节大小、数量和分布情况．结果显示，双侧的第二腰交感节多在腰2椎体的下1／3跨过椎间盘至腰3椎体的上1／3．同时还测量了腰动脉与交感链的相交点，腰交感链与主动脉、下腔静脉的距离等．该组资料为施行化学性腰交感神经节切除的临床应用提供了解剖理论依据．

The Lumbar sympathetic ganglia and their surroundings were examined anatomicallyin 21 human cadavers. On the vertebral column at the level of the second and third lumbar vertebraltheies, the number, distribution and size of the lumbar sympathetic ganglia were observed and analyzed by using 'ganglia scoreff. The results revealed that the second lumbar sympathetic gangllon waslocated most frequently at the Iower third of the second lumbar vertebral fory, the level of L2-3, inter-space and the upper third of the third lumbar vertebral they on both right and left sides. The crossednts of lumbar sympathetic chains and lumbar arteries, the distances between the chains and aboominal aorta and vena cava, and between the chains and sidelines of the front face of vertebral taly werealso measured simultaneously. These results furnish a reliable basis for the clinical practice of chemicallumbar sympathectomy.
