Predictors of neurological morbidity after coronary artery bypass surgery

Abstract

Peripheral vascular atherosclerosis, neurological pathology, aorta-pathology, the occurrence of a perioperative myocardial infarction and the time cohort 1993-1995 are identified as independent risk factors for neurological complications.

Early and delayed stroke after coronary surgery — an analysis of risk factors and the impact on short- and long-term survival

“…Several demographic risk factors behind stroke have been suggested in previous studies [3,16]. CPB exposure has also been addressed, in relation to potential OPCAB benefits [4].…”

“…However, it can be speculated that many of these risk factors depend on how the stroke variable was defined and handled. In the majority of previous studies, including large cohort analyses, stroke was not subdivided into early and delayed form [4,16].…”

Pulsatile extracorporeal circulation during on-pump cardiac surgery enhances aortic wall shear stress

“…The clinical relevance of plaque rupture and mobilization is evident, since neurological complications after ECC in cardiosurgical patients range from 1% to 10% (Bucerius et al, 2003;Janssen et al, 1999), dependent on the type of surgery, and have been reported to reach up to 16% in high risk patients (Wolman et al, 1999). Arteriosclerotic embolism is a major cause of operative stroke, and therefore the influence of different perfusion techniques should be considered.…”

Neurological Damage Related to Cardiac Surgery

“…Incidence of neurologic side effects related to cardiac surgery has been reported to be 1.4% to 6% [1][2][3][4] and can reach up to 9% in patients aged over 75 years, 5,6 or up to 16% when high preoperative risk factors are present. 7,8 In addition, neuropsychological dysfunction may occur in up to 50% of patients.…”

“…7,8 In addition, neuropsychological dysfunction may occur in up to 50% of patients. 1,3,9 Cognitive impairment, usually reversible, can affect immediate or late visual or verbal memory, attention, calculation, or processing information speed. In certain cases, cognitive decline persists 5 to 10 years after the surgical procedure.…”
