Fenestrated Stent Graft Repair for Thoracic Aortic Aneurysm

Total arch replacement and ascending aorta and arch replacement are the gold standard treatments for aortic arch aneurysm and are possible treatment strategies for chronic type A dissection, with good outcomes. However, because total arch replacement is alternative invasive, it can be difficult to perform in some patients. The thoracic endovascular aneurysm repair (TEVAR) landing on zone2 is a less invasive and suitable treatment for descending aortic aneurysm. We challenged to treat the more proximal region of aortic arch with TEVAR. The some type of fenestrated TEVAR were usefull technique for high risk patients. We present the various fenestrated TEVAR procedures. Especially, we designed an endovascular total arch repair procedure with use of in situ fenestration and commercially available devices, and we present our initial experience.
