ABSTRACT
The stent-graft is a device constructed from a stent and vascular graft and is inserted by means of an interventional procedure under imaging guidance. In 1986, Balko et al.1 reported the first stentgraft experiment, in which a Z stent covered with polyurethane was inserted into an animal aorta. In the early 1990s, Parodi et al.2 reported clinical introduction of the stent-graft for abdominal aortic aneurysm. In comparison to the abdominal aortic stent-graft, the thoracic stent-graft has several disadvantages, including difficulties associated with the aortic arch curvature and the relatively large caliber of the stent-graft, and the risk of central nervous system or spinal complication. However, the thoracic stentgraft is advantageous because of minimal procedural invasiveness in comparison to surgical graft replacement. In 1994, Dake et al.3 reported transluminal placement of an endovascular stent-graft for thoracic aortic aneurysm, and Kato et al.4 reported use of a stent-graft for aortic dissection and suggested that the stent-graft could be considered an alternative to surgical treatment.
