Endovascular aneurysm repair has become a primary treatment modality for patients with abdominal aortic aneurysms due to its less invasive nature and improved peri-operative mortality rates compared with conventional open surgery. Long-term, endovascular aneurysm repair is hindered by the need for reintervention due to a variety of reasons. Device improvements are directed toward improving these long-term outcomes. The current manuscript highlights some of the details of the Terumo Aortic TREO abdominal aortic stent-graft, which was approved in 2020 for clinical use by the US FDA. A brief review of the available clinical outcomes from the US trial, as well as experience in the rest of the world, are provided demonstrating its excellent performance.
