目的研究螺旋CT诊断腰椎间盘 突出症并发椎管狭窄的临床价值，为临床 诊断提供参考和借鉴，提高对腰椎间盘突 出症并发椎管狭窄的诊断水平。方法 选 取2011年1月-2013年1月期间我院收治的 58例腰椎间盘突出症并发椎管狭窄的患者 为研究对象，根据其临床资料进行回顾性 分析和总结，评价螺旋CT对诊断腰椎间盘 突出症并发椎管狭窄的临床价值。结果 CT诊断出13例硬膜囊受损，19例椎间盘部 分脱出，9例韧带肥厚，8例侧隐窝狭窄， 7例椎间孔狭窄，诊断正确率为96.5%，与 手术结果相比，p＞0.05，差异没有统计 学意义。结论 螺旋CT对腰椎间盘突出症 并发椎管狭窄具有重要的诊断价值，能清 楚显示椎管狭窄、神经根受压程度及韧带 情况，诊断正确率高，能为患者的后续治 疗提供可靠的依据，值得临床广泛应用和 推广。

Objective This paper is to discuss the clinical value of spiral CT in the diagnosis of lumbar intervertebral disc protrusion concurrently with spinal canal stenosis, in order to provide the reference for clinical diagnosis in the future, and improve the diagnosis level on lumbar intervertebral disc protrusion concurrently with spinal canal stenosis. Methods Fifty eight patients with lumbar intervertebral disc protrusion concurrently with spinal canal stenosis admitted by this Hospital during the period from January, 2011 to January, 2013 were selected as research subjects. The clinical data were retrospectively analyzed and summarized, and evaluated the clinical value of spiral CT in the diagnosis of lumbar intervertebral disc protrusion concurrently with spinal canal stenosis. Results Thirteen patients were diagnosed as dural sac impairment, 19 patients suffered from lumbar intervertebral disc protrusion, 9 patients suffered from ligament hypertrophy, 8 patients suffered from lateral recess stenosis, and 7 patients suffered from intervertebral foramen stenosis, the correct diagnostic rate was 96.5%, the p value was greater than 0.05 when compared to the surgery, and the differences had no statistically significant. Conclusions Spiral CT delivers important clinical diagnostic value in the diagnosis of lumbar intervertebral disc protrusion concurrently with spinal canal stenosis, and it demonstrated the spinal canal, nerve root and the ligament clearly, and had high diagnostic accuracy rate, which can provide reliable basis for the follow-up treatment of patients, and being worthy of wide use and promotions in clinical practices.
