摘　　要：目的　探讨感觉障碍平面定位于胸段的压迫性颈部脊髓病变的临床特点、病因和发病机制。方法　回顾性分析我院 1 992～ 2 0 0 2年经治的 2 2例感觉障碍平面定位于胸段的颈部脊髓病变病人的临床特点。结果　病因为颈椎间盘突出和小脑扁桃体下疝。首发症状为下肢无力、麻木 ,呈慢性进行性进展并逐渐向上累及 ;感觉障碍平面比实际受压平面低 8～ 1 4个脊髓节段为其突出特征 ;有轻、中度肌力减退 ;踝阵挛阳性是另一有重要意义的体征。结论　可能的机理包括机械性压迫和血液供应张障碍。对于有上述临床特征而胸段MRI无异常的病人 。Objective To identify the clinical character, causes and mechanisms of compression cervical myeleterosis with sensory disturbance level locating at thoracic vertebrae. Methods 22 cases of compression cervical myeleterosis with sensory disturbance level locating at thoracic vertebrae were analyzed retrospectively from 1992 to 2002. Results All cases were caused by protrusion of intervertebral disc or cerebrallar tonsillar hernia. The initial symptoms were myasthenia and numbness in lower limbs, and it is a progressive course. The sensory disturbance levels are usually 8～14 spinal cord segments below the actual site of cord compression. There are mild and moderate myasthenia. The positive sign of ankle clonus is an another important sign. Conclusions The possible mechanisms are depressions and ischemia. To avoid errors of diagnosis, the cervical spinal cord MRI should be taken by the patients with clinical characters mentioned above without MRI abnormal in thoracic spinal cord segments.
