Endovascular versus conventional open surgical repair for thoracoabdominal aortic aneurysms.

Background: Thoracoabdominal aortic aneurysms (TAAAs) are a life-threatening condition which remain difficult to treat. Endovascular and open surgical repair (OSR) provide treatment options for patients, however, due to the lack of clinical trials comparing these, the optimum treatment option is unknown.

Objectives: To assess the effectiveness and safety of endovascular repair versus conventional OSR for the treatment of TAAAs.
