Spinal nerve roots often sustain compression injuries. We used a Wistar rat model of the cauda equina syndrome to investigate such injuries. Rapid transient compression of the cauda equina was produced using a balloon catheter. The results were assessed by daily neurological examination and somatosensory evoked potential (SEP) recording before surgery and ten weeks after decompression. Compression of the spinal nerves induced changes in the SEP which persisted for up to ten weeks after decompression, but it had no effect on the final neurological outcome. Our study shows the importance of early surgical decompression for cauda equina syndrome.
脊神经根常遭受压迫性损伤。我们使用马尾综合征的Wistar大鼠模型来研究此类损伤。采用球囊导管对马尾进行快速短暂压迫。通过术前及减压后十周每日的神经学检查和体感诱发电位（SEP）记录来评估结果。脊神经受压导致SEP发生变化，这种变化在减压后持续长达十周，但对最终的神经学结果没有影响。我们的研究表明早期手术减压对马尾综合征的重要性。
