INTRODUCTION: @entity16 are, at the present time, considered among the most important causes of morbidity and mortality after heart surgery. We evaluated their importance and risk factors. @entity1 AND METHODS: We retrospectively reviewed 2, 528 consecutive @entity1 who underwent cardiopulmonary bypass in a single center. In each one, we attended to previous vascular risk factors, such as surgical and postoperative events. We considered four categories of neurologic outcome: (1) persistent @entity51 , (2) stupor or @entity772 , (3) @entity51 , and (4) seizures. We carried out univariant and multivariant statistical analysis, looking for predictors of adverse neurologic events. RESULTS: @entity16 occurred in 76 @entity1 (3%); 36 of them (47%) had persistent @entity51 , 18 (24%) stupor or @entity772 , 18 (24%) @entity51 , and 27 (36%) @entity410 . Twenty-two @entity1 with cerebral adverse outcomes died (29%), the overall mortality among the 2,528 cases being 5%. Predictors of risk were @entity449 and aortic valve surgery, advanced age, female sex, and the use of intra-aortic balloon pump. A longer hospitalization time was noticed among @entity1 with neurological side effects. DISCUSSION: @entity16 are common and serious after heart surgery, as we have noticed with this series, the largest up to now, according to our review of the literature. They increase perioperative mortality and hospitalization time. @entity16 and risk factors in our study are similar to those previously published.
