ABSTRACT
Thoracoabdominal aortic (TAA) aneurysms can be defined as aneurysms that involve the descending thoracic and abdominal aorta. Although less common than abdominal aortic aneurysms, TAA aneurysms appear to be associated with a worse prognosis.[1,14] In these reports, the 2-year survival rate of untreated patients with these extensive aneurysms was less than 30%, with about half of all deaths occurring as a result of aneurysm rupture.[2] The surgical repair of these complex aneurysms can improve this poor survival rate significantly.
