Clinical Study for Evaluating the Safety and Efficacy of Total Endovascular Aortic Arch Repair

Aortic disease is a kind of cardiovascular diseases with very high mortality rate and high risk of surgical treatment. At present, the surgical and endovascular treatment for diseases in the ascending aorta, descending aorta and abdominal aorta are becoming more and more mature. However, due to the complexity of the aortic arch in anatomy, function and pathological changes, the optimal treatment strategy for diseases in the aortic arch has been controversial constantly. This research is a multi-center(four centers), prospective, controlled, large-scale (about 400 subjects) clinical study, using traditional thoracic surgery of aortic arch disease as a control to verify that new techniques for endovascular treatment is not inferior to traditional thoracic surgery in terms of efficiency and safety. Further more, the investigators plan to explore the indications of the application of these new techniques, develop a better diagnosis and treatment program, reduce the risk of such surgical treatment and the incidence of complications, improve clinical efficacy and the overall quality of the disease.
