Objective: Although hybrid arch repair has gained widespread application as an alternative option for high-risk patients, concerns about its long-term durability remain an important issue. The aim of this study was to investigate late complications after hybrid arch repair. Methods: From January 2002 to December 2017, hybrid arch repair was performed in 65 patients with aortic arch disease (median age, 66.1 years; range, 41-86 years). Hybrid arch repair was defined as debranching involving at least one supra-aortic vessel bypass and simultaneous or staged endovascular thoracic stent grafting. We retrospectively analyzed late complications including reintervention, open conversion, and aortic-related death. The median follow-up period was 60.1 months (range, 1-170 months). Results: The in-hospital mortality rate was 6% (4/65). Except for early death (n = 4) and early open conversion (n = 2), late complications were observed in 25 patients (25/59 [42%]). The median time interval between the initial procedure and late complication was 36.6 months (range, 1-92 months). Late complications included delayed type I endoleak (n = 8), distal stent-induced new entry (n = 3), stent migration (n = 3), retrograde type A dissection (n = 2), aortopulmonary fistula (n = 2), aortoesophageal fistula (n = 1), stent fracture (n = 1), infection (n = 1), and sudden death (n = 4). Six of these patients (10%) underwent late open conversion. The overall survival rates at 3 years and 6 years were 71.1 ± 7.4% and 57.2 ± 11.3%, respectively. The aortic event-free rates at 3 years and 6 years were 52.1 ± 7.3% and 39.4 ± 10.3%, respectively. Conclusions: Late complications in hybrid arch repair occurred in a substantial proportion of patients during midterm follow-up. Regardless of zone type, the incidence of late complications was relatively high. This study suggests that timely reintervention and open conversion are important for rescuing patients, but repeated reinterventions and conservative strategies are not recommended. Aggressive management and life-long surveillance after hybrid arch repair are mandatory for better outcomes.
