Single-center retrospective cohort at China Medical University Hospital (Taichung, Taiwan) using fully de-identified electronic health records. Consecutive adults who underwent emergency repair of acute type A aortic dissection between 2021-01-01 and 2025-04-30 were pooled into one cohort. The study measures the incidence and patterns of early postoperative neurological complications and evaluates their association with intensive care unit (ICU) resource use, focusing on prolonged ICU length of stay (LOS ≥ 10 days), ICU and hospital LOS, and duration of mechanical ventilation (MV). No new data collection or patient contact occurs. Institutional Review Board (IRB) approval: CMUH114-REC1-139.
