Implication
May warrant preoperative cerebrovascular risk stratification in cardiac surgery; leaves open optimal mitigation strategies pending prospective trials.
Key Points
- To review the mechanisms, predisposing factors, and clinical consequences of stroke and encephalopathy associated with cardiac surgery.
- Synthesized clinical evidence on postoperative neurological complications among cardiac surgery patients.
- Evaluated physiological mechanisms of brain injury and preoperative risk assessment tools.
- Preexisting cerebrovascular disease substantially increases the risk of stroke and encephalopathy, which drive longer hospital stays, elevated medical costs, and increased mortality.
- Intraoperative cerebral microemboli, systemic hypoperfusion, and new-onset postoperative atrial fibrillation serve as primary drivers of adverse neurological outcomes.

Preoperative evaluation of functionally significant vascular disease of the brain before cardiac surgery

Preoperative evaluation of cerebrovascular disease is essential to identify high-risk patients and mitigate neurological complications after cardiac surgery.
