Type of Oxygenator, Type of Arterial Filter, and Bypass Time, in Relation to Outcome

A whole clinical spectrum of neurological complications has been reported after cardiac surgery, ranging from: fatal cerebral injury, impairment of conscious level, stroke, ophthalmological complications, seizures, spinal cord injury to “miscellaneous CNS abnormalities,” Shaw [1]. Aberg and his colleagues [2–5] found substantial neuropsychological abnormality early on and documented declining rates of abnormality as the performance of perfusion and surgery improved. Recently, several studies have related postoperative neuropsychological changes to such factors as retinal microembolisation, preoperative cerebrovascular disease and bypass time [6–10].
