Three-dimensional analysis of 220 cadaveric hands to the submacroscopic level was done with clear stereoscopic arteriographs. The superficial palmar arch could be grouped into complete (96.4%) and incomplete (3.6%) arches. The complete arch was divided into four types on the basis of the terminal formation of the deep palmar arch. In the deep palmar arch, the complete arch was seen in 76.9% of the hands. This rate was smaller than that in other reports. The second dorsal metacarpal artery was seen in 92%. With regard to formation of the deep palmar arch, half of all the cases exhibited collateral pathways for the palmar side from the dorsum, sometimes the main arterial source of the deep palmar arch. The blood supply of the thumb comes mainly from the princeps pollicis artery, the terminal branch of the superficial palmar arch, and the first dorsal metacarpal artery, which originates from the radial artery or from different combinations of these arteries. The arteries of the thumb are classified by their anatomic course. The princeps pollicis artery (first palmar metacarpal artery) was absent in 2.4%.
使用清晰的立体动脉造影对220只尸体手进行了亚宏观层面的三维分析。掌浅弓可分为完整型（96.4%）和不完整型（3.6%）。完整型弓根据掌深弓的终末形态分为四种类型。在掌深弓中，76.9%的手可见完整型弓。该比例低于其他报告中的比例。92%的手可见第二掌背动脉。关于掌深弓的形成，所有病例中有一半表现出从手背至手掌侧的侧支途径，有时是掌深弓的主要动脉来源。拇指的血液供应主要来自掌浅弓的终末分支拇主要动脉以及起源于桡动脉的第一掌背动脉，或来自这些动脉的不同组合。拇指的动脉根据其解剖走行进行分类。2.4%的手缺如拇主要动脉（第一掌骨掌侧动脉）。
