Abstract [eng] The problem of postoperative neuropsychological disorders is widely addressed in contemporary medical literature; nevertheless the incidence and risk factors of these complications remain controversial. The aim of our study was to detect cognitive decline after on pump coronary artery bypass grafting and identify risk factors associated with this complication. Postoperative cognitive decline (POCD) can be detected in 46% of patients after on pump coronary artery bypass grafting. Age more than 65 years, asymptomatic hemodynamicaly relevant carotid artery stenosis and preoperative depression are independent preoperative predictors of POCD. Low cardiac output syndrome detected postoperatively for more than 48 hours, was three fold increasing the risk of POCD. Patients experiencing POCD were treated in ICU for a significantly longer period of time, even in the absence of cardiovascular complications. ICU time more than 24 hours, was independent risk factor for POCD (OR 3,46). Asymptomatic carotid artery stenosis is the strongest predictor of postoperative neuropsychological complications tremendously increasing the likelihood for developing cognitive abnormalities. Routine screening for craniocervical disease in patients undergoing CABG could help in identification of patients at risk for neurocognitive damage and further prevention of this complication.
