The blood supply patterns to the spinal cord were examined and compared in 15 dogs and 10 cats by use of dissection and radiographic visualization. The lowest percentages of radicular contributions and the smallest diameter vessels were found in the thoracic part of the spinal cord. The central arteries were fewest in number in the thoracic region and unilaterally or bilaterally supplied the gray matter. The percentage of bilaterally distributed central arteries increased from the cervical to the lumbar regions. The anastomotic plexus on the surface of the spinal cord was found to be most dense in the cervical and lumbar regions.
通过解剖和影像学可视化检查并比较了15只犬和10只猫脊髓的血液供应模式。脊髓胸段的神经根供血比例最低，血管直径最小。胸段脊髓的中央动脉数量最少，单侧或双侧供应灰质。双侧分布的中央动脉比例从颈部到腰部逐渐增加。脊髓表面的吻合丛在颈部和腰部最为密集。
