显微手术治疗颈胸段原发性椎管内肿瘤

Microsurgery for Primary Intraspinal Tumor in Cervicothoracic Canal

目的探讨应用显微手术方法治疗颈胸段原发性椎管内肿瘤的效果。方法36例颈、胸段椎管内肿瘤患者,均在显微镜下进行肿瘤切除手术,其中5例采用侧后方入路,31例采用后正中入路。结果肿瘤完全切除29例,大部分切除7例。随访31例,平均14.3（1-35）个月。症状消失19例,减轻9例,无改善3例,无加重及死亡病例。复发5例,再手术4例。结论采用显微手术治疗能最大限度减少肿瘤残留,同时保存脊髓及神经的功能。

Objective To discuss the effect of microsurgery in treatment of intraspinal tumor originated from cervicothoracic spinal canal. Method 36 patients suffered from intraspinal tumor were performed microsurgery via the posterior-lateral approach in 5 and posterior midline approach in 31 cases. Results Tumor total removal was achieved in 29 cases and subtotal removal in 7 cases. Thirty-one cases were followed up for 1 to 35 months （average 14.3 months）. The symptoms disappeared in 19, relieved in 9, and stable in 3. No aggravation or death occurred. Five cases recurred and four received reoperations. Conclusion Microsurgery can furthest reduce the chance of residual tumor and reserve the spinal cord function.
