【摘要】 目的 探讨退行性下胸椎管狭窄症的诊断和手术策略。方法 采用回顾性研究方法对退行性下胸椎管狭窄症的诊断和手术治疗结果进行分析。结果 平均随访26个月(6~58个月)，根据评定标准，优14例，良2例。结论 (1)下胸椎管狭窄症容易误诊的原因：主要是误诊为腰椎管狭窄、病情较轻者定位不明确、合并腰椎管狭窄症或脊髓型颈椎病；(2)手术策略和方式：根据具体情况来处理跳跃性黄韧带骨化症，以及合并腰椎管狭窄、脊髓型颈椎病。采用卷帘式(从下向上卷起椎板)和侧翻式(从侧方翻起椎板)两种方式进行胸椎管减压。

    【Abstract】 Objective To summarize the diagnosis and operative methods for degenerative lower thoracic spinal stenosis.Methods The dingnosis and operative methods of degenerative lower thoracic spinal stenosis was studied retrospectively.Results All cases was followed up for 6~58 months with an average of 26 months. According to the criterion, 14 cases had excellent results, and 2 had good results.Conclusion (1)The causes of the misdiagnosis of degenerative lower thoracic spinal stenosis are as follows: misdiagnosising as lumbar stenosis, no existing physical signal of location, coexisting lumbar or cervical stenosis. (2)The operative methods are selected according to clinical situation. ......
