Eighty-six elective aortic arch surgeries were performed during the analyzed period, including 25 patients (29%) in group A and 61 patients in group B (71%). The hemiarch procedure was more frequently performed in group A (17 patients, 68%) in comparison to group B (21 patients, 34%) (P =0.008). More procedures on the descending aorta were performed in group B (27 patients, 44%) than in group A (6 patients, 24%) (P =0.09). Stroke was recorded in 6 patients (20%) from group A and 5 patients (8.2%) from group B (P =0.002). Five-year survival was 60±9.8% for group A, and 81±6.2% for group B (log-rank test, P =0.003).
