目的　总结脊髓髓内肿瘤的显微手术经验 ,并对其并发症的处理及疗效进行评价。方法　对 48例髓内肿瘤采用显微外科手术。术中取侧卧位或半坐位 ,正中切口 ,尽量做到全切 ,并观察其术后的并发症及处理。结果　本组室管膜瘤、星形细胞瘤、脂肪瘤和血管网状细胞瘤分别占髓内肿瘤的 3 7.5 %、2 9.2 %、2 0 .8%、10 .4% ,其全切率分别为 88.9%、2 8.6%、10 .0 %、60 .0 % ;1例转移瘤全切。术后早期有感觉缺失 ,主要并发症有感染。 48例全部随访 ,平均 3 0 .4个月 ,大部分病人术后 1～ 3个月功能好转或无继续恶化 ,47例存活 ,1例死亡。结论　脊髓髓内肿瘤以良性及低恶性度肿瘤多见 ,手术效果较好 ,应尽早手术 Objective To summarize the experience of microsurgical operation of spinal intramedullary tumors and evaluate the treatment and efficacy of its complications. Methods 48 cases of intramedullary tumors using microsurgery. Take the lateral position or semi-sitting during surgery, the incision, try to be fully cut, and observe the postoperative complications and treatment. Results The group of ependymoma, astrocytoma, lipoma and vascular reticular cell tumors accounted for 3 7.5%, 2 9.2%, 20.8%, 10.4% respectively of intramedullary tumors, Respectively, 88.9%, 28.6%, 10.0%, 60.0%; 1 case of metastases resection. Early loss of sensory loss, the main complications of infection. All 48 cases were followed up for an average of 30.4 months. Most of the patients had functional improvement or no worsening 1 to 3 months after operation, 47 survived and 1 died. Conclusion Spinal intramedullary tumors with benign and low-grade tumors more common, the effect is better, as soon as possible surgery
