延颈髓肿瘤12例显微外科治疗

目的：探讨不同病理类型的延颈髓肿瘤临床特征和影像学诊断，及手术时机和技巧。方法：回顾性分析12例延颈髓肿瘤的病理类型、临床表现、辅助检查、手术切除程度及临床疗效。结果：12例延颈髓肿瘤中全切除11例，占91．67％，1例纤维坏死组织近全切除，无手术死亡率，全组病例临床表现均得到改善。结论：延颈髓肿瘤可通过MRI检查作出正确诊断，对绝大多数肿瘤可通过显微外科手术切除，对恶性肿瘤应辅以放射治疗。

Surgical treatment of medulla oblongata and intramedullary spinal cord tumors

Objective To discuss the clinical features and neuroimage of various kinds of medulla oblongata and intramedullary spinal cord tumors,the optimal operation time,and the surgical skills of these tumors.Methods In twelve case of medulla oblongata and in-tramedullary spinal cord tumors,The tumor histological types,clinical manifestations,adjuvant examinations,the extent of tumor resection and operative outcome were analysed retrospectively.Results Eleven of12tumors were totally resected(91.6%),one case of fibronecrotic tissue was subtotally resected,there was no operative mortality,clinical manifestation of all cases improved.Conclusion Medulla oblongata and intramedullary spinal cord tumors can be diagnosed by MRI scan,most of them can be total resected.It is necessary to perform radio therapy.[
