Current challenges in open versus endovascular repair of ruptured thoracic aortic aneurysm

Abstract A ruptured thoracic aortic aneurysm is considered a surgical emergency; it is often fatal if it is not identified and managed immediately. Since the recognition of this clinical entity, open surgical repair has been the "gold standard" method of management. However, open surgical repair is associated with high morbidity and mortality rates. Among high-risk patients and as an alternative, thoracic endovascular repairs have since transpired, aiming to reduce the morbidity and mortality rates associated with open repair in a number of patients. The results of both treatment options are debatable, yet there is not a full concurrence on the advantages of endovascular repair in comparison to open repair as the gold standard method of managing such emergency cases, particularly ruptures involving the ascending and aortic arch. This literature review aimed to examine current literature evidence for the use of open or endovascular repair in the emergency setting of a ruptured thoracic aortic aneurysm.
