Background
The aims of this study were to assess the peri-operative morbidity, mortality and long-term survival of octogenarians undergoing ATAAD repair, and to compare open and closed distal anastomosis techniques.
Methods
This was a single-centre retrospective study (2007-2021). Open versus closed distal anastomosis were compared. Uni and multi-variable logistic regression analyses were performed to identify independent predictors of in-hospital mortality. Kaplan-Meier and Cox proportional hazards methods were used to compare long-term survival.
Results
Fifty octogenarians patients were included (median age - 82 years, closed distal – 22, open distal - 28). Median CPB time was 187 minutes (open distal vs closed distal group; 219 minutes vs 115.5 minutes, p30 days or return to theatre; HR; 4.1, p=0.02) predicted adverse survival. Open distal anastomosis did no impact survival.
Conclusions –
ATAAD repair in selected octogenarians has favourable short and long-term survival. There is no significant difference between open versus closed distal anastomosis strategies.
