Brief Summary:
This retrospective cohort study aims to evaluate the efficacy of a Bilateral Modified Catheter Antegrade Cerebral Perfusion (Modified bACP) technique in acute Type A aortic dissection surgery. Medical records from January 1, 2021, through October 31, 2024, at China Medical University Hospital will be reviewed. The primary outcomes include in-hospital mortality and stroke rate, while secondary outcomes include ICU/hospital stay, mechanical ventilation duration, and other postoperative complications (e.g., acute kidney injury, sepsis, myocardial infarction).
Detailed Description:
Background and Rationale Acute Type A aortic dissection (ATAAD) is a life-threatening condition requiring urgent surgical repair. Prolonged circulatory arrest increases the risk of neurological complications. Bilateral antegrade cerebral perfusion (bACP) has shown potential to reduce ischemic injury. However, conventional bACP requires additional surgical access. This study examines a Modified bACP approach that may reduce surgical trauma while maintaining adequate cerebral perfusion.
Objectives This retrospective cohort study evaluates whether Modified bACP improves postoperative outcomes compared to conventional perfusion strategies in ATAAD surgery at China Medical University Hospital (2021/1/1-2024/10/31).
Methods We will collect and analyze medical records of adult patients who underwent ATAAD repair, comparing those who received Modified bACP to those managed with conventional perfusion.
Outcome Measures
Primary Outcomes:
In-hospital mortality 30-day mortality
Secondary Outcomes:
Hospital length of stay (day) ICU length of stay (day) Mechanical ventilation duration (hours) Need for tracheostomy Stroke Postoperative neurological deficit Paraplegia Coma Atrial fibrillation (Af) Myocardial infarction Acute kidney injury (AKI) Dialysis requirement Reoperation for bleeding Sepsis Significance This study aims to provide comprehensive data on the safety and efficacy of Modified bACP in ATAAD surgery, potentially improving neurological protection and reducing other major complications and resource utilization. The findings may guide clinical practice and inform future protocol developments.
