The arterial supply of the spinal cord of the rat in the thoracolumbar region was studied in 26 Wistar albino rats. Contrary to the situation in man, and in variance with earlier reports for the rat, we did not observe a single large artery at the thoracolumbar level supplying a large part of the spinal cord. The anterior spinal artery at this level seemed to be adequately supplied by three to five principal arteries. A considerable variation in the distribution and size of these feeding arteries was observed. It is concluded that the equivalent of the artery of Adamkiewicz is not invariably present in the rat and it would appear that the vascular anatomy of the rat spinal cord is not as similar to that of man as has previously been reported.
在26只Wistar白化大鼠中研究了胸腰段大鼠脊髓的动脉供应。与人类的情况相反,并且与之前关于大鼠的报道不同,我们在胸腰段未观察到单一的大动脉供应脊髓的大部分区域。该水平的脊髓前动脉似乎由三到五条主要动脉充分供血。观察到这些供血动脉的分布和大小存在相当大的差异。得出的结论是,大鼠并非总是存在与Adamkiewicz动脉相当的动脉,并且大鼠脊髓的血管解剖结构似乎并不像之前报道的那样与人类相似。
