Edinburgh Aortic Summit 2025

The Scottish dedicated aortic service was established in 2018.We present medium term survival outcomes for patients who have undergone a total aortic arch replacement procedure followed by either an open or endovascular second stage procedure to treat complex arch and thoracoabdominal aortic disease.Thirty-three consecutive patients who underwent either elective or emergency total arch replacement followed by a second stage procedure between 2018 and 2022 were included.These data were analysed using the R programming software.Survival analysis was performed through generation of Kaplan Meier curves, with censoring at either death or date of last follow-up.Taking the date of total arch replacement as day zero, open second stage repair had a one year survival of 93% and two year survival of 81%.Endovascular second stage repair had a one year survival of 87% and a 2 year survival of 80%.Median time between first and second stage repair was 203 days (IQR 72:311).In this cohort there is no evidence of a medium term survival difference between open and endovascular second stage procedure following total arch replacement p = 0.83.This small observational cohort has limitations, and significant confounding exists since surgical options were often influenced by underlying patient factors.These data add to an understanding of survival outcomes in a complex surgical domain.
