对 146 具尸体的上肢和下肢动脉模式进行了研究。主动脉的直径、沿母干的重要分支的起源点、分叉的水平以及任何“异常”或变化都被记录下来。同时记录每个受试者的右侧和左侧，特别注意单侧的变化，而不是双边出现的变化。对上肢和下肢动脉模式的变化进行了一般性调查。主要变异的百分比频率在本系列中确定，并与解剖学文献中给出的百分比频率进行比较。调查结果呈现在两个表格中，其中列出了主要变化，并指出了它们仅在右侧或左侧或在个别受试者的两侧出现的频率。在整个变化范围内，单侧发生频率大约是双侧发生频率的两倍。一般来说，除了大约三分之一的情况外，动脉变异可能不会出现在两侧。成人的动脉肢体模式在胎儿早期就已经建立。作者认为，模式的变化必须被视为基因突变。尽管这些突变在左右两侧独立地表现出来，但它们偶尔在两侧出现的频率比纯粹偶然发生的要高。
The arterial patterns of the upper and lower limbs have been investigated in 146 cadavers. The diameters of the main arteries, the points of origin of the important branches along the parent trunks, the levels of the bifurcations, and any "abnormalities" or variations were noted. In each subject the right and left sides, were recorded simultaneously, special attention being paid to the unilateral as against the bilateral appearance of the variations. A general survey is given of the variations of arterial patterns in the upper and lower limbs. The percentage frequency of the main variations was determined in the present series, and was compared with the percentage frequency as given in the anatomical literature. The results of the investigation are presented in two tables where the main variations are listed, and their frequency occurrence on the right or left side only, or on both sides in individual subjects is indicated. Over the whole range of variations the unilateral frequency occurrence was about double that of bilateral occurrence. In general, an arterial variation may not be expected to be present on both sides, except in approximately 1 out of 3 cases. The adult arterial limb patterns are already established during early fetal existence. In the author''s opinion, variations in patterns must be considered as genetic mutations. Although these mutations manifest themselves independently on the right and left sides, their occasional bilateral appearance is more frequent than can be accounted for as a purely fortuitous occurrence.
