摘要
目的 :探讨MRI在腰椎间盘突出症手术失败病例诊治过程中的应用价值。方法 :分析 83例腰椎间盘突出症再手术患者的MRI表现。其中男性 5 6例 ,女性 2 7例。年龄 2 7～ 71岁 ,平均 43 4岁。距初次手术时间 8个月～ 6年。结果 :椎间盘突出 2 4例 ,椎管狭窄 43例 ,假性脊膜突出 3例 ,硬膜纤维化及神经根周围瘢痕形成 11例 ,腰椎不稳 2例。结论 :MRI对于引起腰椎手术失败的多数病因均有诊断价值 ,尤其适用于未作内固定的病例。
Objectives:To evaluate the application value of MRI in diagnosis and treatment of patients with failed lumbar disc surgery.Methods:Eighty three patents who had lumbar disc surgery eight months to six years previously,and had required a second operative procedure,have been reviewed for MRI findings.There were 56 men and 27 women.Their age ranged 27 to 71 years with an average of 43.4 years.Results:Of these patients,24 patients were identified with disc herniation,43 with spinal stenosis,three with pseudomeningocele,11 with epidural fibrosis and perineural scarring,and two with lumbar spinal instability.Conclusions:MRI examination is valuable to diagnosis of most causes of failed back surgery and is especially indicated in the evaluation of noninstrumented postoperative patients.
