| Popis: | Background All patients with type A aortic dissections, regardless of age, are recommended urgent aortic surgery. However, studies exploring long term outcomes in survivors are sparse, and especially, the significance of age on long-term outcomes remain unclear. Purpose We described and compared incidences across age groups of post-discharge readmission, repeated aortic surgery, and death in patients who survived surgery and hospitalization for type A aortic dissection. Methods Using data from Danish nationwide registries, we identified patients hospitalized with Stanford type A aortic dissections from 2006–2018. Survivors of hospitalization and surgery on the ascending aorta and/or aortic arch comprised the study population (Figure 1). Using cumulative incidence plots taking death into account as a competing risk and Cox regression analysis, we described long-term outcomes (rehospitalizations, repeated aortic surgery, and death) and compared different age groups. The diagnosis of type A aortic dissection in the registries used, was validated from 191 clinical records to have a positive predictive value of 94.8%. Results Of 606 initial survivors of surgery and hospitalization with type A aortic dissection, 236 (38.9%) were 69 years old (group III). Figure 2 shows cumulative incidences of outcomes according to age. During the first year, 62.5% were re-hospitalized (median number of days hospitalized was 2 days (IQR 1–8 days) and 1.4% underwent repeated aortic surgery with no significant differences across age groups (P=0.68 and P=0.39, respectively). Further, 5.9% died (group I: 3.0%, group II: 8.3%, group III: 7.4%, P=0.04). After 10 years of follow up, 8.0% had undergone repeated aortic surgery (group I: 11.5%, group II: 8.5%, group III: 1.6%, P=0.04) and 10.2% (group I), 17.0% (group II), and 22.2% (group III) had died (P=0.01). In adjusted analyses, no age differences were found in one-year outcomes, while age >69 years (group III) compared with age Conclusion Among survivors of type A aortic dissections, rehospitalizations the first year after discharge were common among all age groups, but survival was high. Repeated aortic surgery was rare, and significantly more common among younger than older patients. Evaluations of quality of life in survivors of type A aortic dissections are needed.
