目的 进一步探讨提高脊椎管内神经鞘瘤的早期诊断率及显微外科手术疗效。 方法 回顾 1990年 5月～ 2 0 0 0年 5月收治的脊椎管内神经鞘瘤 42例 ,其中颈段 8例 ,胸段 2 1例 ,腰段 13例。全部病例均经 X线、脊椎造影、CT或 MRI等影像学检查及病理切片诊断。 结果 早期确诊率仅 36% ,术前确诊率为 86%。36例肿瘤获得全部切除 ,6例肿瘤大部分切除。术后经 1～ 10年随访 ,优良率 91.6%。 结论 要提高手术治疗效果 ,关键在于早期诊断。显微外科手术切除脊椎管内神经鞘瘤 ,能有效地防止肿瘤的复发 ,提高了治疗的效果
Objective To further investigate the improvement of the early diagnosis of schwannoma in spinal canal and the efficacy of microsurgery. METHODS: We retrospectively reviewed 42 cases of spinal schwannomas treated between May 1990 and May 2000. Among them, there were 8 cases of cervical plexus, 21 cases of thoracic segment, and 13 cases of lumbar segment. All cases were diagnosed by X-ray, spinal radiography, CT or MRI and other imaging examinations and pathological sections. Results The early diagnosis rate was only 36% and the preoperative diagnosis rate was 86%. Thirty-six tumors were totally resected, and six tumors were mostly resected. After 1 to 10 years of follow-up, the excellent and good rate was 91.6%. Conclusion The key to improving the surgical treatment is early diagnosis. Microsurgical removal of spinal schwannomas can effectively prevent the recurrence of tumors and improve the efficacy of treatment.
