中文摘要:

  目的：了解脊髓型颈椎病颈椎管扩大成型术后，颈椎间盘突出自行消失的原因并由此提出脊髓型颈椎病新的致病学说。方法：自１９９４年６月～１９９８年５月对脊髓型颈椎病行后路单开门椎管扩大成型术患者行临床及ＭＲＩ检查。结果：８例患者，术后４～１３个月，平均５．８个月复查时，颈椎ＭＲＩ检查发现，其术前ＭＲＩ显示的颈椎间盘突出影像消失，相应部位硬膜、脊髓无压迫。结论：（１）颈椎间盘退变突出后，出现颈椎节段性不稳定，刺激突出间盘周围组织，产生炎症性反应；（２）颈椎间盘突出、颈椎退变或颈椎管狭窄，致硬膜外腔压力增高，导致硬膜外静脉回流障碍，出现硬膜外静脉瘀滞、怒张。上述为脊髓型颈椎病发病的又一可能因素
