Abstract
BACKGROUND: To explore evolving surgical techniques and outcomes for aortic arch surgery. METHODS: A total of 2435 consecutive patients underwent aortic arch repair with hypothermic circulatory arrest between 2008 and 2018 in 12 institutions across Canada. Trends in patient characteristics, surgical techniques, and in-hospital outcomes, including major morbidity or mortality, were examined. RESULTS: = 0.12). Outcomes remained the same over time for urgent or emergent cases. CONCLUSIONS: Outcomes have improved over the past decade in Canada for elective aortic arch surgery, in the context of operating on smaller aortas, and more frequent use of moderate hypothermia and antegrade cerebral perfusion. Further research is needed to improve stroke rates and outcomes in the emergency setting.
