1.我们在41具成人尸体计82例的腰部交感干解剖中,发现腰交感节的数目变化在2—6个之间;其中拥有三个节者最多,共38例,占46.3％。其次为四个节,计22例,占26.8％。在各个节中,以第五腰节最恒定,其次为第二腰节。两干形态对称的在腰部很少见到。 2.腰部交感干节一般均位于同数椎骨与下位椎骨之间。 3.相邻的两个或三个节可相互合并成一个体积较大的节。左右两干合并节共有28 个,占总节数10.2％,其中以GL_(2-3)合并次数最多。 4.有时除交感于节以外,尚可见到在交通支或交感根上存有小的副节,共发现27个副节,其中有21个存在于下腰部。 5.腰交感干在不同腰椎平面可发生干分裂现象,在82例中有20干分裂为两条或两条以上。 6.自每个节发出的交通支可朝向上、下及水平方向。GL_1及GL_2的支以上下为多,GL_3的支以向下及横行为多,GL_4及GL_5的支多向下,每个节连接支的数目为0—6条。 7.每个腰神经接受的交通支为1—5条,其中以接受两支者为多见。 8.文中讨论了有关腰交感神经截除的解剖学问题。
1. In our study, we found that the number of lumbar sympathetic joints varies between 2-6 in 82 cases of adult lumbar sympathetic trunk dissection. Among them, 38 cases (46.3%) had the most three sections. Followed by four sections, accounting for 22 cases, accounting for 26.8%. In each section, the fifth is the most constant, followed by the second. Two dry shape symmetry rarely seen in the waist. 2 lumbar sympathetic joints are generally located in the same number of vertebrae and lower vertebra. 3. Adjacent two or three sections can be merged into one larger section. There are 28 merging sections, accounting for 10.2% of the total number of sections, of which GL_ (2-3) has the highest number of mergers. 4. In addition to the sympathetic section, sometimes there are still visible in the traffic branch or sympathetic root there are a small deputy section, a total of 27 deputy section found, of which 21 exist in the lower loins. 5 lumbar sympathetic dry lumbar spine plane can occur in the split phenomenon, in 82 cases of 20 stem split into two or more. 6. The traffic branch issuing from each section may face upward, downward and horizontally. The branches of GL_1 and GL_2 are mostly up and down, the branches of GL_3 are mostly downward and horizontal, the branches of GL_4 and GL_5 are downward and the number of branches of each branch is 0-6. 7. Each lumbar nerve transport branch is 1-5, which is more common to accept two. 8. Anatomy of the lumbar sympathectomy is discussed.
