This paper assesses the early outcomes of patients treated with a double inner-branched arch endograft in a single, tertiary-care institution.<h4>Methods</h4>All consecutive cases of elective endovascular arch repair from 2016 to 2022 were included in a prospective database. All procedures were performed using the custom-made Relay^® (Terumo Aortic-Bolton Medical Inc., Sunrise, FL, USA) double inner-branched endograft; an extra-anatomical bypass was associated in all cases to preserve the patency of supra-aortic trunks.
