【摘要】：研究目的 在防腐成年人尸體標(biāo)本上對腰椎前的主動脈分又，髂總靜脈匯合點，骶正中動靜脈以及腰動靜脈的位置分布及變異進(jìn)行描述和統(tǒng)計分析。為腰椎間盤的人工椎間盤置換術(shù)提供解剖學(xué)依據(jù)，以提高手術(shù)的安全性和有效性。 材料與方法： 對30具標(biāo)本的腰椎及其前面的附屬結(jié)構(gòu)完整的尸體標(biāo)本進(jìn)行測量，測量的主要指標(biāo)有：(1) 主動脈分叉與髂總靜脈匯合點位置的定性描述和定量測量。(2) 骶正中動靜脈的發(fā)出點與走行，骶正中動靜脈的數(shù)量與缺失，，動靜脈之間的伴行情況。(3) 腰動靜脈的數(shù)量與缺失，各節(jié)段腰動靜脈發(fā)出點位置的定性描述，腰動靜脈左右共干與上下共干的概率以及腰動靜脈的其他變異。 結(jié)果： 主動脈分叉在L_(4，5)椎間盤水平最為集中。而在L_5椎體下分，L_5S_1椎間盤沒有分布。在L_(4，5)椎間盤水平以上的分布呈遞減趨勢。而髂總靜脈匯合點集中分布在L_5椎體上分，在L_4椎體中分及其以上沒有分布，靜脈的匯合點的位置總是低于主動脈分叉點的位置。聯(lián)合兩者考慮，分為三種類
[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
