摘要
目的探讨64排螺旋CT及肌电图联合应用诊断椎间孔型腰椎管狭窄症的临床价值。方法回顾性分析507例手术证实腰椎管狭窄症患者,其中29例术前普通CT、MRI扫描检查均未发现明确椎管狭窄情况,经肌电图联合64排螺旋CT薄层扫描初步定位,再进行手术探查性治疗。结果 29例经手术证实均为特殊类型腰椎间孔狭窄,术后参照改良Macanab[2]分级标准进行疗效评价,优19例,良7例,可3例,差0例,优良率89.7%。术前及术后疗效差异有明显统计学意义。结论 64排螺旋CT薄层扫描联合肌电图能够更加准确定位腰椎管狭窄部位,从而提高手术的治疗效果。
Objective To explore the clinical value of the combination of 64 slice spiral CT and EMG to diagnose the lumbar foraminal stenosis. Methods 507 cases with lumbar spinal stenosis confirmed by surgery in patients,were retrospectively analyzed. 29 of whom were not found the lumbar spinal canal stenosis exactly before ordinary CT and MRI scans. Initial positioning by EMG combined with 64-slice spinal CT scanning,then surgical exploration treat- ment. Results 29 cases confirmed by surgery were all special types of lumbar spinal stenosis. Effect of surgery were excellent in 19 cases ,good in 7 cases ,fair in 3cases and poor in 0 cases. Preoperative and poetoperative efficacy differ- ences were statistically significant. Conclusion The lumbar spinal stenosis site can be positioned more exactly by 64 slice spinal CT combined with EMG. Thus the surgical treatment can be improved.
