Introduction to Surgery

Replace the diseased thoracic aortic segment with vascular graft, the operation method and postoperative curative effect vary with the anatomical part of the thoracic aorta. During the procedure, some technical support may be needed as well, such as cardiopulmonary bypass, deep hypothermia systemic circulation or selective cerebral perfusion. The surgical mortality rate is about 5% to 10%. Surgery complications may include bleeding, severe arrhythmia, insufficient coronary blood supply and complications of central nervous system. 1-year survival rate after surgery is 80% to 90%, and 5-year survival rate is 60% to 80%.

Thoracic Endovascular Aortic Repair(TEVAR)

Introduction to Surgery

Refers to a minimally invasive approach that involves placing a stent-graft in the thoracic or thoracoabdominal aorta for the treatment of a variety of thoracic aortic pathologies. TEVAR was initially used to provide treatment to patients who were not considered to be surgical candidates, and maintained much lower perioperative morbidity and mortality compared with traditional open surgery. With the development of endovascular devices, TEVAR can be also performed for some thoracic aortic pathologies involving branches of aortic arch, including using unibody single-branch endograft.
