摘要目的 探讨脊髓髓内海绵状血管瘤(SIC)的临床特点与显微外科技巧.方法 回顾性分析2005年6月至2012年12月北京天坛医院和泰安市中心医院经病理学证实的21例SIC患者临床资料,患者年龄平均39岁.对所有患者进行显微外科手术治疗并进行随访.结果 根据病理生理过程本组病例起病方式为:(1)急性起病型:5例(23.8％);(2)反复发作型:9例(42.8％);(3)缓慢进展型:7例(33.4％).21例病灶全切20例,次全切1例.术后随访神经功能活动改善13例,无变化6例,加重2例.结论 SIC的不同临床特征与其病理生理学过程有关.不同类型SIC在MRI扫描中有特征性表现.正确的手术方法和熟练的显微手术技巧是提高SIC手术疗效的关键.

abstractsObjective To explore the clinical features and microsurgical treatment of spinal intramedullary cavernomas (SICs).Methods A total of 21 patients with pathologically confirmed SIC undergoing microsurgical resection of cavernomas at Beijing Tiantan Hospital and Taian Central Hospital from June 2005 to December 2012 were reviewed retrospectively.Results The postoperative neurological status improved (n=13) and remained unchanged (n =6) and aggravated (n =2).Conclusion The clinical features of SICs are related with their different pathological processes.Magnetic resonance imaging (MRI) is specific for the diagnosis of SICs.Appropriate strategies and refined microsurgical techniques are essential for improving the clinical efficacies of SICs.
