Several therapeutic approaches can be used, including staged carotid endarterectomy and CABG, simultaneous carotid endarterec- tomy and CABG, or similar variations that use endovascular stenting as the primary carotid intervention. At present, no prospective RCTs comparing neurological outcomes after these different treatment strategies in patients with coexisting carotid artery disease and CAD have been reported.865 The incidence of postoperative delirium after CABG is 10%, similar to that reported after noncardiac surgery.866 868 The risk factors for postoperative delirium are similar for cardiac and noncardiac surgery and include advanced age, preexisting cognitive impairment, and vascular disease.866,868,869 The burden of intraoperative cerebral microemboli does not pre- dict the presence or severity of postoperative delirium.870 The development of postoperative delirium has been linked to functional decline at 1 month, short-term cognitive decline,871 and risk of late mortality.867,872 5.2.1.3.
