Objective To describe a novel approach, 3D printing guiding stent graft fenestration, for fenestration during endovascular aneurysm repair for juxtarenal abdominal aortic aneurysm. Methods A 69-year-old male with juxtarenal abdominal aortic aneurysm underwent endovascular aneurysm repair with "off the label" fenestrated stent graft. To precisely locate the fenestration position, we reconstructed a 3D digital abdominal aortic aneurysm model and created a skin template covering this abdominal aortic aneurysm model. Then the skin template was physically printed and the position of the visceral vessel was hollowed out, thereby helping in locating the fenestration on stent graft. Results and conclusions With the help of this 3D printed skin template, we fenestrated the stent graft accurately and rebuilt the bilateral renal artery successfully. This is the first clinical case that used 3D printing guiding stent graft fenestration, which is a novel approach for precise fenestration on stent graft on the table during endovascular aneurysm repair.
目的 描述一种用于肾周腹主动脉瘤血管内修复术开窗的新方法——3D打印引导支架移植物开窗术。方法 一名69岁肾周腹主动脉瘤男性患者接受了“超适应证使用”的开窗支架移植物血管内动脉瘤修复术。为精确确定开窗位置，我们重建了一个3D数字腹主动脉瘤模型，并创建了一个覆盖该腹主动脉瘤模型的皮肤模板。然后将皮肤模板进行实体打印，并将内脏血管的位置镂空，从而有助于在支架移植物上定位开窗位置。结果与结论 在这个3D打印皮肤模板的帮助下，我们准确地对支架移植物进行了开窗，并成功重建了双侧肾动脉。这是首例使用3D打印引导支架移植物开窗术的临床病例，该方法是血管内动脉瘤修复术中在手术台上对支架移植物进行精确开窗的新方法。
