Based on analysis of arteriography in 300 subjects of different age and sex, as well as 4 human fetuses, we demonstrated that in the course of an individual's life aortal bifurcation moves caudally. In a fetus, bifurcation is located at the level of L3, while in an adult it moves to the level of L4. After the age of 50, the position of bifurcation moves gradually caudally and can reach--in the advanced age--as far as the level of L5/S1 disc. The changes of position during a lifetime are statistically significant. A shift in the position of the bifurcation of abdominal aorta can be of significance for surgical interventions on the abdominal aorta.
基于对300名不同年龄和性别的受试者以及4例人类胎儿的动脉造影分析，我们证明在个体生命过程中主动脉分叉会向尾侧移动。在胎儿中，分叉位于L3水平，而在成年人中它移至L4水平。50岁以后，分叉的位置逐渐向尾侧移动，在高龄时可到达L5/S1椎间盘水平。一生中位置的变化具有统计学意义。腹主动脉分叉位置的改变对于腹主动脉的外科手术可能具有重要意义。
