Descending thoracic aortic aneurysm management has gained momentum and became a topic of many debates at international levels since the evolution of endovascular repair. Ruptured descending thoracic aortic aneurysm is a clinical emergency which is associated with high mortality and morbidity rates if not managed properly. Prior to thoracic endovascular aortic repair (TEVAR), open repair (OR) was the gold standard management, however since the evolution of TEVAR, this has changed. Several centers have reported many of their experiences and published that TEVAR can provide equal or even better perioperative outcomes when compared to OR, although the evidences can be of only short term and could be biased at different levels at the time of publication. This review article is aimed to examine current literature evidences behind the use of TEVAR vs. OR and the reported comparative clinical outcomes.
