Introduction
Thoracic-abdominal aortic aneurysm refers to aortic aneurysm lesions crossing the diaphragm, involving the thoracic aorta and the abdominal aorta. Therefore, the thoracic and abdominal aorta should be repaired. In recent years, despite the vigorous development of endovascular treatment, surgical repair technique is still an important method for successful treatment of thoracic-abdominal aortic aneurysms.
