目的 :探索胸椎椎管内肿瘤的诊断特点 ,评估显微外科切除疗效。方法 :对 35例胸椎椎管内肿瘤的临床特点、影像改变、显微外科切除的疗效进行分析。结果 :2 9例髓外肿瘤中 ,9例采用显微外科技术切除 ,未见任何手术合并症 ,受压症状解除快 ,疗效佳 ,优于普通手术切除的 2 0例 ;6例髓内肿瘤中 ,采用显微外科切除 4例 ,肿瘤切除率约 70 % ,普通手术切除 2例 ,切除率约 2 5 %。结论 :依据影像学特点 ,采用显微外科技术切除 ,具有解剖结构层次清晰 ,对正常脊髓及其周围组织损伤或刺激小 ,肿瘤切除较彻底等优点。
Objective: To explore the diagnostic features of thoracic spinal tumors and assess the effect of microsurgical resection. Methods: The clinical features, imaging changes and microsurgical resection of 35 cases of thoracic spinal canal tumors were analyzed. Results: Among 29 cases of extramedullary tumors, 9 cases were treated by microsurgical technique. There was no surgical complications, the symptoms of pressure relief were relieved quickly and the curative effect was better than that of common surgical resection. Six cases of intramedullary tumors , 4 cases were removed by microsurgery, the tumor resection rate was about 70%, 2 cases were removed by ordinary surgery, and the resection rate was about 25%. Conclusion: According to the characteristics of imaging, microsurgical technique is used to excise it. It has the advantages of clear anatomical structure, less damage or stimulation to the normal spinal cord and its surrounding tissues, and complete tumor resection.
