Risk analysis for early mortality in emergency acute type A aortic dissection surgery: experience of Tokyo Acute Aortic Super-network

Abstract OBJECTIVES We investigated the various pre- and postoperative complications related to early (30-day) mortality after open surgery for acute type A aortic dissection. METHODS Data from the Tokyo Acute Aortic Super-network database spanning January 2015 to December 2017 were retrospectively reviewed. Pre- and postoperative factors related to early postoperative mortality were assessed in 1504 of 2058 (73.0%) consecutive patients [age: 66.6 (SD: 13.5) years, male: 52.9%] who underwent acute type A aortic dissection repair. RESULTS The early mortality rate following surgical repair was 8.9%. According to multivariable analysis, male sex [odds ratio (OR) 1.670, 95% confidence interval (CI) 1.063–2.624, P = 0.026], use of percutaneous circulatory assist devices (n = 116, 7.7%) including extracorporeal membrane oxygenators or intra-aortic balloon pumps (OR 4.857, 95% CI 2.867–8.228, P
