CT引导硬膜外皮质类固醇注射治疗腰椎椎管狭窄

CT-guided epidural steroid injections in lumbar spinal stenosis

目的 评价CT引导经神经孔硬膜外皮质类固醇注射治疗腰椎椎管狭窄的短期及长期疗效。方法 经CT证实存在腰椎椎管狭窄且保守治疗无效的36例患者,于CT引导下行硬膜外皮质类固醇注射治疗。通过患者治疗前、治疗后2周及治疗后1年的视觉模拟疼痛评分以评价其疗效。结果 对所有36例患者行治疗后2周及1年随访,1 9例(5 2 .8%)患者有较好短期疗效,其中1 5例(41 .6 %)患者有较好长期疗效。1 5例患者(41 .6 %)对此治疗短期疗效表示满意。1 2例(33.3%)患者对其长期疗效表示满意。结论 CT引导经神经孔硬膜外类固醇注射可以缓解部分腰椎椎管狭窄患者的疼痛症状并改善患者的生活质量。

Objective To identify the short and long-term therapeutic benefits of CT-guided transforaminal epidural steroid injections in lumbar spinal stenosis. Methods Thirty six patients with lumbar spinal stenosis shown by CT underwent CT-guided transforaminal epidural steroid injections because of irresponsible to conservative treatment. Patients were evaluated by visual analogue scale (VAS) before the initial injection, at 2 weeks and 1 year after the injection.Results All patients were followed up for 2 weeks and 1 year. 19 ( 52.8%) patients had successful short-term outcome, and 15 ( 41.6%) had long-term outcome. 15 ( 41.6%) patients satisfied with the short-term result and 12 (33.3%) were satisfactory with the long-term result.Conclusions CT-guided transforaminal epidural steroid injection may reduce the pain and improve the quality of life in some patients with lumbar spinal stenosis.
