Frozen elephant trunk (FET) has gained popularity since its inception. Nevertheless, the optimal approach for managing aortic arch pathologies remains subject of debate. This meta-analysis compared outcomes between patients undergoing FET and those undergoing conventional aortic repair. Systematic searches were conducted up to February 2024.
