A 67-year-old male patient was admitted with an enormous twisted thoracoabdominal aortic aneurysm (TAAA) with multiple branch arteries stenosis and occlusion. Three-dimensional (3D) printing technology combined with mechanics was used for developing a transparent model of lesion to simulate the segment of diseased aorta. A stent graft was deployed in the 3D model to make a physician-modified stent graft (PMSGs) on table. The locations of the opening of branches were marked twice during operation. The PMSG was successfully deployed during the surgery and repaired the TAAA, with no endoleak and all the branched arteries patency in follow-up. This technique could offer precision individualized therapy and could simplify the procedure process greatly.
一位 67 岁男性患者因巨大扭曲的胸腹主动脉瘤（TAAA）伴多发分支动脉狭窄和闭塞入院。采用三维（3D）打印技术结合力学原理，制作病变部位透明模型，模拟病变主动脉节段。在 3D 模型中置入支架移植物，在手术台上制作医师改良支架移植物（PMSG）。术中两次标记分支开口位置，成功在术中展开 PMSG，无内漏，所有分支动脉通畅。随访。该技术可为患者提供精准的个体化治疗，大大简化手术流程。
