Objective: This study aimed to evaluate the results of emergency operations for acute type A aortic dissection, especially in octogenarians. Our surgical approach for octogenarians aims to conclude with the least invasive procedure possible, with Hemiarch replacement being the primary choice whenever feasible.
Methods: From March 2012 to November 2023, 449 consecutive patients underwent surgical repair for acute type A aortic dissection at our institution. 113 patients aged 80 years or older were included in this retrospective study. The primary endpoint was early mortality, and the secondary endpoint was long-term mortality. The mean age of the cohort was 84.8 years.
Results: Of the 113 octogenarians with AAD (A), isolated Hemiarch replacement was performed in 105 (93%), total arch replacement in 5 (4.4%), and Bentall procedure in 3 (2.7%). Five patients (4.4%) died within 30 days, and 12 (10.6) died in the hospital more than 30 days after surgery. Ten (8.8%) had a new stroke and 7 (6.2%) had mediastinitis. The overall postoperative survival was 76%, 74%, and 50% at 1, 3, and 5 years, respectively.
Conclusions: The results of emergency surgery for octogenarians were acceptable. Octogenarians should not be refused this life-saving emergency operation.
