Abstrakt: Whereas the operative results for thoracic aortic aneurysms (TAA) have improved in recent years, the results for distal arch aneurysms (DAA) remain unsatisfactory. We report herein the initial results of open stent grafting (OSG) applied using an improved endotracheal tube for surgical treatment of high-risk DAA. OSG was used to treat DAA in five men aged 69–80 years (mean, 77 years). Four cases involved chronic obstructive pulmonary disease, and the remaining case involved both ischemic heart disease and chronic renal failure. Previous surgical repairs of an abdominal aortic aneurysm had been performed in four patients, and thoracoplasty and reconstruction of the lower extremities had been performed in the remaining patient. Under selective cerebral perfusion, OSG with revascularization of two cerebral branches was performed in two patients, whereas OSG with total arch replacement was performed in three patients. The procedure was successful in all cases. There were no complications related to cerebrospinal disorders, and complete thrombosis of the aneurismal sac was achieved in all cases. The new deployment method using an endotracheal tube offers numerous advantages, including reduced aortic wall injury and accurate placement of the stent graft in the operative field. These initial results suggest that this specific approach makes OSG a useful surgical procedure in the treatment of high-risk DAA. [ABSTRACT FROM AUTHOR]
