The present investigation has shown that the anatomy of the spinal cord arteries in the rat and in man is closely related but not identical. The main differences are: (1) The poor supply of radicular arteries to the lower cervical and upper thoracic segments of the cord is more marked in the rat, (2) the great ventral radicular artery of Adamkiewicz is less subjected to variations in position in the rat, (3) penetrating branches from the pial arterial plexus are absent in the rat, (4) surface anastomoses between the ventral and the dorsal spinal arteries do not occur in the rat except occasionally at the lower end of the cord. Intramedullary arterial anastomoses in the lumbosacral cord of the rat seems to be species specific.
目前的研究表明，大鼠和人类脊髓动脉的解剖结构密切相关但并不相同。主要差异在于：（1）大鼠脊髓下颈段和上胸段的根动脉供血较差更为明显；（2）Adamkiewicz大前根动脉在大鼠中位置变化较小；（3）大鼠不存在软膜动脉丛的穿支；（4）大鼠脊髓腹侧和背侧动脉之间除偶尔在脊髓下端外不发生表面吻合。大鼠腰骶段脊髓内的动脉吻合似乎具有物种特异性。
