1、3D打印技术辅助颈椎高位多段脊索瘤手术临床应用万方数据马立敏①张余+周烨、D陈加荣①蓝国波①黄文汉D姚孟宇①摘要目的：探讨3D打印技术辅助颈椎高位多节段脊索瘤手术切除的临床价值。方法：两例颈椎高位脊索瘤患者，术前行64排双源螺旋CT扫描，进行三维重建，快速成型制作出与实体1：1大小的颈椎模型，对颈椎模型术前制定手术方案，手术规划和模拟手术，指导手术治疗。结果：术前模拟手术使手术时间缩短，减少术中失血量，手术中参照模型，达到术中精确置钉效果。结论：3D打印技术能全面、直观、精确地显示颈椎肿瘤各部位解剖结构

2、的空间关系，对于颈椎高位多节段脊索瘤治疗均有很强的临床指导作用，使手术更精确、更可靠、更方便，它在颈椎肿瘤的治疗中有着广阔前景。关键词脊索瘤颈椎3D打印Doi：lO．3969／j．issn．1673—7571．2014．06．024【中图分类号】R318．1【文献标识码】AEnblocResectionofaMultilevelHigh—cervicalChordomaInvolvingC一2andC一3Using3DPrinting／MALi—min，ZHANGYu，ZHOUYe，etal／／Chin
