【摘要】 目的总结儿童髓内肿瘤的病理特点、显微手术和治疗效果,并进行探讨。方法81例儿童脊髓内肿瘤均经手术切除和病理证实,对手术治疗的效果进行回顾性分析。结果儿童髓内肿瘤以星形细胞瘤24例(29.6%)、室管膜瘤13例(16.0%)和表皮样囊肿11例(13.6%)为多见,不同的病理类型的肿瘤,切除率不同。放疗用于高度恶性的肿瘤。椎板复位术可以有效地减少脊柱畸形的发生率。结论大多数的髓内肿瘤组织学上为低级别星形细胞瘤(Ⅰ~Ⅱ级)、室管膜瘤和胚胎残余组织肿瘤,积极手术切除能够获得满意的疗效。更多还原

【Abstract】 Objective To investigate the results of microsurgical treatment for intramedullary tumors in children.Methods Eight-one children with intramedullary tumors which were proved by histopathological examination underwent microsurgical treatment in this institute.The clinical data including the pathological types,treatment,and long term results were retrospectively analyzed.Results Astrocytomas((29.6%)),ependymomas((16.0%)),and epidermoids((13.6%)) were the most common pathological types in pediatric intramedullary tumors.Moreover,the pathological classification was related to resection rate.Radiotherapy was applied to the malignant tumors after operation.Thirty-nine patients were followed up for an average of 6 years,(74.3%) of these patients got the functional recovery of grade ⅠorⅡ according to McCormick grading system.The long-term follow-up showed that laminoplasty could effectively decrease the incidence of spinal deformities after operation.Conclusions Microsurgical treatment can obtain good results for children with intramedullary tumors.更多还原
