Background: Endovascular arch repair technology is driven in large part by the assumption that open arch operations are high-risk. We wanted to evaluate the clinical results of open arch reconstruction in the modern era in a large group practice. Methods: From October 2003 to June 2014, 567 patients underwent aortic arch operations: hemiarch repair was performed in 429 patients (75.7%; group A), total arch repair in 129 (22.7%; group B), and patch repair in the remaining 9 (1.6%). The procedure was an emergency in 88 patients (20.5%) in group A and in 41 patients (31%) in group B. Redo sternotomy after a previous aortic operation was performed in 35 patients (8.2%) in group A and in 28 patients (22%) in group B. Results: Permanent neurologic deficits were diagnosed in 12 patients (2.8%) in group A and in 3 patients (2.4%) in group B. No spinal cord injuries occurred. Mortality at 30 days was 4% (17 patients) in group A and 5.4% (7 patients) in group B. Patients in group A were younger than in group B (mean age, 61.3 vs 63.6 years; . p = 0.06). Older age (odds ratio, 1.05; 95% confidence interval, 1.01 to 1.09; . p = 0.0087) and extracorporeal circulation time (odds ratio, 1.01; 95% confidence interval, 1 to 1.01; . p < 0.001) were predictors of perioperative 30-day mortality. Age (odds ratio, 1.05; 95% confidence interval, 1.01 to 1.08; . p = 0.006) was the only predictor for neurologic dysfunction. Survival at 2, 6, and 8 years was 90%, 80%, and 69%, respectively, for group A, and 85%, 70% and 62%, respectively, for group B. Conclusions: These results set a standard against which endovascular technology needs to be compared.
