CT检查参数对腰椎管狭窄症的诊断价值及与疗效、腰椎功能改善的相关性分析

The Diagnostic Value of CT Examination Parameters in Lumbar Spinal Stenosis and the Correlation Analysis with Curative Effect and Improvement of Lumbar Function

选取我院60例腰椎管狭窄症(LSS)患者作为研究组,同期健康者60例作为对照组,探究CT检查参数对LSS的诊断价值及与疗效、腰椎功能改善的相关性。结果显示,研究组椎管面积、硬膜囊面积、椎管矢径、椎管横径、侧隐窝矢径、侧隐窝角小于对照组(P<0.05);CT各参数联合诊断LSS的AUC值大于任一参数单独诊断;疗效优良患者术后3个月椎管面积、硬膜囊面积、椎管矢径、侧隐窝矢径、侧隐窝角大于治疗前及非优良患者(P<0.05);经偏相关性分析发现,CT检查参数与疗效显著相关(P<0.05)。说明LSS疗效、腰椎功能改善情况与椎管面积、硬膜囊面积、椎管矢径等关系密切,CT检查对指导临床完善手术方案有重要意义。

Sixty patients with lumbar spinal stenosis(LSS)were selected as the research group,and 60 healthy patients during the same period were selected as the control group.The diagnostic value of CT examination parameters in LSS and the correlation with the curative effect and the improvement of lumbar function were explored.The results showed that the spinal canal area,dural sac area,spinal sagittal diameter,spinal transverse diameter,lateral recess sagittal diameter,and lateral recess angle of the research group were smaller than those of the control group(P<0.05).The AUC value of CT parameters in the combined diagnosis of LSS was greater than that of any parameter alone.The spinal canal area,dural sac area,spinal sagittal diameter,lateral recess sagittal diameter and lateral recess angle of patients with excellent curative effect 3 months after the operation were larger than those before treatment and non-excellent patients(P<0.05).After partial correlation analysis,CT examination parameters were still significantly related to the efficacy(P<0.05).It shows that the efficacy of LSS and the improvement of lumbar spine function are closely related to the spinal canal area,dural sac area and spinal sagittal diameter.CT examination is of great significance in guiding the clinical improvement of the surgical plan.
