Despite the perioperative mortality risk, the late outcome of endovascular arch repair presents a low rate of aorta-related deaths and reinterventions and acceptable midterm survival. Furthermore, more than one-third of the aneurysms' diameters decrease over 5 years as a measure of the long-term efficacy of treatment. Retrograde type A dissection remains a major concern in the perioperative period and careful arch approach is required.
Despite the older age and a higher comorbidity profile in patients with challenging aortic arch disease suitable and selected for endovascular arch repair, no significant differences were detected in perioperative and 4-year outcomes compared with the younger patients undergoing open arch total repair. An endovascular approach might also be a valid alternative to open surgery in average-risk patients with aortic arch diseases requiring 0 to 1 landing zones, when morphologically feasible. However, larger concurrent comparison and longer follow-up are needed to confirm this hypothesis.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
