METHODS Between January 1996 and December 2022, 120 patients underwent aortic arch reoperations after primary proximal aortic surgery. We retrospectively analysed perioperative data, as well as early and mid-term outcomes in these patients. RESULTS Indications for arch reintervention included new aortic aneurysm in 34 patients (28.3%), expanding post-dissection aneurysm in 36 (30.0%), aortic graft infection in 39 (32.5%) and new aortic dissection in 9 cases. Two patients underwent reoperation due to iatrogenic complications. Thirty-one patients (25.8%) had concomitant endocarditis. In-hospital and 30-day mortality rates were 11.7% and 15.0%, respectively. Stroke was observed in 11 (9.2%) and paraplegia in 1 patient. Prior surgery due to aneurysm [odds ratio 4.5; 95% confidence interval (CI) 1.4–17.3] and critical preoperative state (odds ratio 5.9; 95% CI 1.5–23.7) were independent predictors of 30-day mortality. Overall 1- and 5-year survival was 65.8 ± 8.8% and 51.2 ± 10.6%, respectively. Diabetes mellitus (hazard ratio 2.4; 95% CI 1.0–5.1) and peripheral arterial disease (hazard ratio 4.7; 95% CI 1.1–14.3) were independent predictors of late death. The cumulative incidence of reoperations was 12.6% (95% CI 6.7–20.4%) at 5 years. Accounting for mortality as a competing event, connective tissue disorders (subdistribution hazard ratio 4.5; 95% CI 1.6–15.7) and interval between primary and redo surgery (subdistribution hazard ratio 1.04; 95% CI 1.02–1.06) were independent predictors of reoperations after redo arch surgery. CONCLUSIONS Despite being technically demanding, aortic arch reoperations are feasible and can be performed with acceptable results. [ABSTRACT FROM AUTHOR]
