    ObjectiveTo evaluate the efficacy and safety of a zone 0 landing aortic stent graft with handmade fenestrations for the preservation of all supra-aortic branches in thoracic endovascular aortic repair (TEVAR).MethodsThis study included 13 consecutive patients who underwent TEVAR using zone 0 landing handmade fenestrated stent grafts to preserve all supra-aortic branches from July 2016 to April 2017. Technical success was defined as the resolution of the primary aortic pathology as well as the preservation of all supra-aortic branches through the accurate alignment of the fenestration. Outcomes including technical success, perioperative morbidity and mortality, requirement of secondary interventions, and graft patency were analyzed.ResultsIn this study, 11 patients presented with aortic dissection, 1 presented with thoracic aortic aneurysm with impending rupture, and 1 presented with penetrating aortic ulcer of the thoracic aorta. The technical success rate of the primary procedure was 100%. Over a mean follow-up of 20 months, secondary endovascular procedures were performed in 6 patients to resolve 3 cases of stent graft-induced new entry, 2 cases of type Ib endoleak, and 1 case of new false lumen formation. During the study period, no complication resulting from proximal landing and fenestration occurred.ConclusionsOur experience of using handmade fenestrated stent grafts revealed preliminary results of using the grafts to preserve all supra-aortic branches in TEVAR, and results demonstrated the feasibility of this technique for achieving total arch replacement endovascularly in selective patients. Further technical advancement is anticipated, and larger studies with long-term follow-up are required.Copyright © 2019 The American Association for Thoracic Surgery. Published by Elsevier Inc.
