The unfavorable vessel anatomy is still a major challenge in the endovascular aneurysm repair,with usually insufficient or even no proximal/distal landing zone for the stent-graft.During recent years,several articles have been published concerning the new approach of multiple stents to the treatment of aneurysm by reducing the stent porosity to encourage laminar flow,preserving branch patency,and promoting thrombus formation in the aneurysm.1,2 We herein report the use of multiple overlapping stents in the treatment of thoracoabdominal aortic aneurysms.
