BackgroundManagement of acute type A aortic dissection (AADA) presenting with cardiopulmonary arrest (CPA) may require aggressive cardiopulmonary resuscitation (CPR), including extracorporeal CPR followed by aortic repair. This study evaluated the early and long-term outcomes of patients with preoperative CPA related to AADA.MethodsBetween September 2003 and August 2019, 474 patients with AADA were brought to our hospital, 157 (33.1%) presenting with CPA. Their mean age was 74.3 ± 11.3 years and prevalence of out-of-hospital CPA 90%, and causes of CPA were cardiac tamponade in 75%, hemothorax in 10%, and coronary malperfusion in 10% of cases. In the same time periods 2974 patients with CPA were transported, and AADA was 4.8% of all cause of CPA.ResultsReturn of spontaneous circulation was achieved in 26 patients (17%) and extracorporeal CPR was required in 31 (20%); 131 CPA patients (83%) died before surgery, 24 (15%) underwent aortic repair, and 2 (1%) received nonsurgical care. Hospital mortality was 90%, and none survived without aortic repair. Of patients achieving return of spontaneous circulation 17 underwent aortic repair, 13 survived, and 5 fully recovered. All patients with extracorporeal CPR died: 24 before surgery and 7 postoperatively. There were significant differences in hospital mortality between patients who did and did not undergo aortic repair (P < .01). Aortic repair was the only significant predictor of long-term survival (P < .01).ConclusionsAADA with CPA is associated with significantly high mortality; however aortic repair can be performed with a 30% likelihood of functional recovery, if return of spontaneous circulation is achieved. Preoperative extracorporeal membrane oxygenation is not recommended in this patient cohort.Copyright © 2021 The Society of Thoracic Surgeons. Published by Elsevier Inc. All rights reserved.
