摘要
目的探讨基于3D打印技术建立急性A型主动脉夹层根部模型对主动脉根部病变诊治的临床意义。方法根据急性A型主动脉夹层累及主动脉根部的病理解剖情况进行系统分类,归纳总结出7种急性A型主动脉夹层根部模型分型,依次将各分型的256CT增强扫描主动脉断层影像数据导入3D slicer软件进行图像优化、分割及三维重建,经过FreeCAD软件的简化、Blender软件的细节调整及上色预览等步骤,完成7种模型的三维数据重建,最后通过Stratasys Objet J750打印机进行3D模型打印。结果通过3D打印技术成功重建出7种急性A型主动脉夹层根部模型。模型具有可重复使用、辨识度高、耐久等特点,能够清晰、多维角度展现急性A型主动脉夹层累及主动脉根部的解剖特点及病理改变。结论3D打印技术可有效重建急性A型主动脉夹层根部模型,为急性A型主动脉夹层根部处理策略及方法提供有力支持。
Objective To explore the clinical significance in the diagnosis and treatment of aortic root disease by reconstructing acute type A aortic dissection root model based on 3D printing technology.Methods According to the pathological anatomy of aortic root involved by acute type A aortic dissection,systematically classifying seven types of acute type A aortic dissection root models.Scanning the tomographic image of aortic root by using 256 CT and importing the scanned data into 3D slicer software for image optimization,segmentation and three-dimensional reconstruction.Then using FreeCAD and Blender software for image simplification,adjustment and color preview.Finally printing the 3D model with Stratasys Objet J750 printer.Results Seven types of acute type A aortic dissection root models were successfully reconstructed through 3D printing technology.With the characteristics of reusability,easy manipulation,and durability,these models can present the anatomical features and pathological changes of acute type A aortic dissection involving aortic root clearly and multi-angle.Conclusion 3D printing technology can effectively reconstruct acute type A aortic dissection root models,which provides strong support for the treatment strategy and method of acute type A aortic dissection root.
