Surgical Strategy for Aortic Arch Aneurysms in Octogenarians

BACKGROUNDS The purpose of this study was to evaluate the short- and mid-term outcomes of open aortic arch surgery and debranching thoracic endovascular aortic repair( TEVAR) in octogenarians. METHODS Between 2011 and 2019, 26 patients with atherosclerotic aortic arch aneurysms underwent surgery at our institution [open aortic arch surgery( group O):10 patients, debranching TEVAR(group D):16 patients]. RESULTS There was no operative death in either group. The mean length of hospitalization and intensive care unit stay were 49 and 13 days in group O and 12 and 2 days in group O, respectively. Kaplan-Meier analyses of overall survival (1/6/12/24/36/48 months) showed mortality rates of 100/100/88/88/70/70% in group O and 100/100/87/61/43/26% in group D, respectively. CONCLUSIONS The acceptable outcomes was demonstrated in octogenarians underwent both open aortic arch surgery and debranching TEVAR. Because of early postoperative recovery, debranching TEVER is considered to be a feasible alternative to conventional open aortic arch surgery in octogenarians.
