摘要
目的探讨螺旋CT对腰椎间盘突出症并发椎管狭窄的诊断价值。方法对2008年1月～2009年3月期间CT诊断为腰椎盘突出症并发椎管狭窄的45例患者的CT资料进行回顾性分析。结果 5例硬膜囊脂肪层消失或不对称,硬膜囊受压变形,神经根被推压移位;4例腰椎间盘后缘弧形突出,位于椎体后缘的中央;13例并发黄韧带肥厚(6～8mm),5例黄韧带肥厚且伴有钙化,18例均见增厚的黄韧带压迫硬膜囊或神经根使之变形或移位;侧隐窝狭窄9例;椎间孔狭窄者4例。结论螺旋CT可准确显示腰椎小关节突增生肥大、椎间盘突出及椎管狭窄,窗宽、宽位的调整对提高CT诊断准确率具有重要意义。
Objective To evaluate spiral CT of the lumbar disc herniation complicated with spinal stenosis diagnosis. Methods The CT diagnosis data of 45 patients lumbar disc herniation complicated with spinal stenosis from January 2008 to March 2009 were retrospectively analyzed Results The five cases of dural fat layer disappears, or asymmetric, dural compression deformation, displacement of nerve root compression pushed; four cases of posterior lumbar disc arc prominent in the posterior margin of the Central; 13 cases of concurrent yellow ligament hypertrophy （6-8mm）, 5 cases yellow ligament hypertrophy and calcification, were seen in 18 cases of thickening of the yellow ligament sac or nerve root compression so that deformation or displacement; lateral recess stenosis 9 cases; vertebral 4 cases among the narrow hole. Conclusion Spiral CT can clearly demonstrate the lumbar facet hypertrophy, disc hemiation and spinal stenosis; adjustment of window width wide bit is important to improve the diagnostic accuracy of CT.
