[Determinants of long-term outcome for operative survivors of acute aortic dissection].
Predictability of aorta-related complications and survival was examined in 79 operative survivors of acute aortic dissection. Follow-up was 94.9% complete and totaled 458 patient-years. Actuarial survival was 93 +/- 3% (+/- S.E.) (n = 43) at 5 years, and 74 +/- 8% (n = 13) at 10 years. Survival was significantly lower in patients having neurological complication. Freedom from aorta-related complications was 82 +/- 5% (n = 37) at 5 years, and 67 +/- 8% (n = 11) at 10 years. Multivariate Cox regression analysis identified residual entry and leak on anastomotic site as independent predictors of aorta-related complications. We conclude that in the treatment of acute aortic dissections, reducing the incidence of residual entry and leak on anastomotic site improves long-term outcome.
