    【摘要】目的 探討三维(3D)打印技术在复杂主动脉疾病腔内治疗中的应用。方法 回顾性分析24例复杂主动脉疾病患者的资料，术前根据24例患者的CT血管造影(CTA)进行主动脉3D重建，将病变区域进行3D打印，选择中空透明材料制作3D打印模型并消毒，术中根据3D打印模型将支架“预开窗”并缝制铂金弹簧圈，重装支架后在体内完成主体支架的释放和分支支架的选择并释放。术后观察疗效、并发症和随访情况。结果 24例包括12例复杂腹主动脉瘤、11例胸主动脉夹层、1例胸腹主动脉瘤，均在术前完成病变段主动脉3D模型打印，根据模型数据辅助制定手术方案，手术均顺利。24例术前3D打印模型测量和术中造影各项数据比较差异均无统计学意义(P均> 0.05)。主动脉夹层患者术后真腔最大直径较术前增大、术后假腔最大直径较术前减小;主动脉瘤患者术后瘤体最大直径较术前减小(P均 0.05). For patients with aortic dissection， the maximum diameter of the true lumen was significantly increased， whereas that of the false lumen was considerably decreased after surgery (both P < 0.05). For aortic aneurysm patients， the maximum diameter of the aneurysm was significantly decreased after surgery (P < 0.05). No severe complications， such as bleeding or organ failure， occurred postoperatively. CTA at postoperative 3 months showed that the stents were located in proper position ......
