Objective:This single-center retrospective study evaluated postoperative outcomes in Stanford type A acute aortic dissection (AAAD) patients presenting with preoperative cardiopulmonary arrest (CPA) between January 2021 and May 2025.

Methods:Among 390 consecutive AAAD cases undergoing emergency surgery, 18 (4.6%) presented with CPA. We assessed 30-day mortality, return of spontaneous circulation (ROSC), and use of preoperative veno-arterial extracorporeal membrane oxygenation (VA-ECMO).

Results:The 30-day mortality was 72.2%. ROSC occurred in 4 cases (22.2%), and ROSC-positive patients had significantly lower mortality (p=0.022). Preoperative VA-ECMO was used in 7 cases (38.9%), none of whom survived (p=0.013).

Conclusions:AAAD with preoperative CPA carries extremely high mortality, but patients achieving ROSC may benefit from urgent surgical intervention. VA-ECMO appears to confer no survival advantage. Early survivors often achieve favorable long-term outcomes, in line with prior literature.
