Background
Use of the Frozen Elephant Trunk (FET) device to manage complex surgical
pathologies of the aorta (such as acute Type A aortic dissection) has
gained popularity since its introduction in the early 2000s. Though the
distal anastomosis was traditionally performed at aortic Zone 3
(Z-3-FET), preference gradually shifted towards Zone 2 (Z-2-FET) in
favour of improved surgical access and clinical outcomes. This review
seeks to elucidate whether proximalisation of arch repair to Zone 0
(Z-0-FET) would further improve postoperative outcomes.
