Ascending aorta pseudoaneurysm (AAP) is a rare but life-threatening complication of atherosclerosis, endocarditis, chest trauma, transcatheter or cardio-thoracic procedures. Since surgical repair is burdened by high morbidity and mortality, percutaneous closure is nowadays considered a valuable cost-effective therapeutic alternative. Due to unpredictability and complexity of local anatomy, no standardized technique and device are advised. In this setting, 3D printing technology could significantly help in planning trans-catheter approach. This article reports on a 3D printed model-guided percutaneous closure of a huge AAP using an Amplatzer Septal Occluder (Abbott, Plymouth MN) implanted by the recently commercialized Amplatzer Trevisio Intravascular Delivery System.

使用新型 Amplatzer Trevisio 血管内输送系统的 3D 模型引导的经导管闭合升主动脉假性动脉瘤

升主动脉假性动脉瘤 (AAP) 是动脉粥样硬化、心内膜炎、胸外伤、经导管或心胸手术的一种罕见但危及生命的并发症。由于手术修复的发病率和死亡率很高，因此经皮闭合现在被认为是一种有价值的具有成本效益的治疗选择。由于局部解剖结构的不可预测性和复杂性，不建议使用标准化的技术和设备。在这种情况下，3D 打印技术可以显着帮助规划经导管方法。本文报道了使用最近商业化的 Amplatzer Trevisio 血管内输送系统植入的 Amplatzer 隔膜封堵器（Abbott, Plymouth MN）对巨大 AAP 进行 3D 打印模型引导的经皮闭合。
