Thirty adult upper extremities were used to study the blood vessels of the hand by angiography, cross-sectional measurement and operative microscopic dissection. The arteries in the middle segment of the palm are arranged in three planes, while in the upper or lower segment there are two planes only. The division of the territories of the radial and ulnar arteries are not same in the three different layers. There are three main anastomotic pathways between the radial and ulnar arteries in the radial-ulnar direction, while in the palmar-dorsal direction there are three anastomotic zones between the palmar and dorsal planes. According to the rate of appearance, sources, cross-sectional area, irrigation territories and anastomoses of the arteries in the three segments, the clinical significance in the reimplantation of the amputated hand through the palm has been discussed.
使用30个成人上肢通过血管造影、横断面测量和手术显微镜解剖来研究手部血管。手掌中段的动脉排列在三个平面，而在上段或下段仅有两个平面。桡动脉和尺动脉在三个不同层面的供血区域划分不同。桡动脉和尺动脉在桡尺方向有三条主要吻合途径，而在掌背方向掌侧和背侧平面之间有三个吻合区。根据三个节段动脉的出现率、来源、横截面积、供血区域和吻合情况，探讨了经手掌进行断手再植的临床意义。
