Abstract

Background: Emergency surgery for acute type A aortic dissection (AAAD) was usually avoided or denied in octogenarians because of high surgical mortality. Refined surgical techniques and improved postoperative care have led to an improved in-hospital outcome. However, a significant number of operative survivors suffered from postoperative complications and had compromised quality of life. We sought to assess the clinical outcome of emergency surgery using a standard conservative approach in octogenarians with AAAD.

Methods: From 2004 to 2021, 123 patients underwent emergency surgery for AAAD by one surgeon using a standard conservative approach with right subclavian artery cannulation, no aortic cross-clamp, selective antegrade cerebral perfusion, moderate systemic hypothermia, reinforced sandwich technique, and a strategy of limited aortic resection. Hospital and late outcomes were assessed in patients with age >80 years.

Results: Eighteen patients (15%) were octogenarians with seven males (39%) and median age of 82 years (range, 80-89). Hypertension was present in six patients (33%). None had diabetes mellitus, Marfan, or bicuspid aortic valve. Dissection was intramural hematoma in six (33%) and DeBakey type I in 15 patients (83%). Cardiac tamponade with shock was present in seven patients (39%). Ascending aortic grafting was performed in 17 patients, and additional hemiarch replacement in one patient. The hospital mortality rate was 17% (3/18). Fourteen patients (82%) were alive and well at discharge.

Conclusions: Emergency surgery for AAAD using a standard conservative approach showed an improved outcome in octogenarians. The majority of patients could return home with an acceptable living.
