Open aortic arch surgery: 10 years' single-center experience.

Introduction: Open aortic arch surgery is a complex cardiac surgical procedure.

Aim: We reviewed the 10-year outcomes of elective aortic arch aneurysm surgery in a single cardiac surgical center.

Material And Methods: The analysis includes all patients who underwent elective aortic arch surgery at our institution between January 2010 and December 2020. The study population was divided into group A consisting of patients operated on during the first 5 years, and group B, including patients operated on during the subsequent 5 years. The groups were compared with regard to baseline characteristics, scope of the surgery, operative and postoperative data as well as morbidity and mortality.

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

Conclusions: After completion of the learning curve, open aortic arch surgery is associated with acceptable early mortality, low incidence of stroke, and a high 5-year survival rate.
