【摘要】：研究目的在防腐成年人尸体标本上对腰椎前的主动脉分又，髂总静脉汇合点，骶正中动静脉以及腰动静脉的位置分布及变异进行描述和统计分析。为腰椎间盘的人工椎间盘置换术提供解剖学依据，以提高手术的安全性和有效性。材料与方法：对30具标本的腰椎及其前面的附属结构完整的尸体标本进行测量，测量的主要指标有：(1) 主动脉分叉与髂总静脉汇合点位置的定性描述和定量测量。(2) 骶正中动静脉的发出点与走行，骶正中动静脉的数量与缺失，，动静脉之间的伴行情况。(3) 腰动静脉的数量与缺失，各节段腰动静脉发出点位置的定性描述，腰动静脉左右共干与上下共干的概率以及腰动静脉的其他变异。结果：主动脉分叉在L_(4，5)椎间盘水平最为集中。而在L_5椎体下分，L_5S_1椎间盘没有分布。在L_(4，5)椎间盘水平以上的分布呈递减趋势。而髂总静脉汇合点集中分布在L_5椎体上分，在L_4椎体中分及其以上没有分布，静脉的汇合点的位置总是低于主动脉分叉点的位置。联合两者考虑，分为三种类
[Abstract]:Research purposeThe distribution and variation of anterior aorta, common iliac vein, middle sacral arteriovenous and lumbar arteriovenous were described and analyzed on the cadavers.To provide anatomical basis for artificial disc replacement of lumbar intervertebral disc, in order to improve the safety and effectiveness of the operation.Materials and methods:The lumbar vertebrae of 30 specimens and the cadaveric specimens with complete accessory structures in front of them were measured.The main measures were as follows: 1) qualitative description of the junction point between aortic bifurcation and common iliac vein, and quantitative measurement of the origin and movement of the median sacral arteriovenous, the number and absence of the median sacral arteriovenous, and the quantitative measurement of the position of the confluence point between the aortic bifurcation and the common iliac vein.The number and absence of lumbar arteriovenous, the qualitative description of the location of the origin of each segment of lumbar arteriovenous, the probability of common trunk and left and right trunk of lumbar arteriovenous, and other variations of lumbar arteriovenous.Results:The aortic bifurcation was most concentrated at the level of L _ S _ 4 ~ (5) intervertebral disc.And there is no distribution of intervertebral discs in L5 subvertebrae.The distribution above the disc level showed a decreasing trend.The common iliac vein confluence was distributed in the L5 vertebrae, but not in the L4 vertebrae or above, and the position of the venous confluence was always lower than that of the aortic bifurcation point.Combine the two into three categories
