Abstract Neurologic complications following cardiac surgery result in increased morbidity and mortality. The incidence of stroke is 2\% to 4\%, but is substantially higher in patients with a prior history of stroke. The success of off-pump techniques in altering this risk is controversial. The efficacy and safety of simultaneous carotid endarterectomy and coronary artery bypass surgery are still debated. Mechanical clot retrievers may offer new opportunity to treat postoperative large, middle cerebral artery strokes. The risk of cognitive deficits is debatable but may be due to factors other than the use of bypass and may not differ from similar deficits after noncardiac surgery. Short-term cognitive deficits usually resolve by 1 to 3 months. Long-term risks are not clearly established. Novel approaches may decrease the incidence of neurocognitive dysfunction. Postoperative seizures may result from global or focal cerebral ischemia due to hypoperfusion, particulate or air emboli, or metabolic causes. Newer anticonvulsant drugs may offer additional management opportunities.
