The distribution of flow divider offset, branch angle, and angular asymmetry in a collection of 70 human aortic bifurcations are reported. A computer algorithm was used to determine these parameters objectively. The mean values with standard deviations and ranges are: 1) magnitude of flow divider offset = 1.4 +/- 1.4 mm (range = 0.04 to 8.1 mm); 2) branch angle = 35.0 degrees +/- 11.1 degrees (range = 10.4 degrees to 61.3 degrees); and 3) angular asymmetry = 15.3 degrees +/- 12.9 degrees (range 0.2 degrees to 56.1 degrees). Since these parameters have been shown to have a significant influence on hemodynamic shear, their variability suggests a corresponding variability in the fluid dynamic stresses to which the bifurcations were exposed in life.
报告了70例人体主动脉分叉中分流器偏移、分支角度和角度不对称性的分布情况。使用计算机算法客观地确定这些参数。均值及标准差和范围如下：1）分流器偏移量大小=1.4±1.4毫米（范围=0.04至8.1毫米）；2）分支角度=35.0度±11.1度（范围=10.4度至61.3度）；3）角度不对称性=15.3度±12.9度（范围0.2度至56.1度）。由于这些参数已被证明对血流动力学剪切力有显著影响，它们的变异性表明分叉在生命过程中所承受的流体动力应力存在相应的变异性。
