Cerebral Emboli Detected During Bypass Surgery are Associated with Clamp Removal Stroke 25:2398-2402, Barbut,D.,et al, 1994 See this aricle in Pubmed Article Abstract Embolic signals were detected in all patients.Of all embolic signals,34% were detected as aortic crossclamps were removed and another 24%as aortic partial occlusion clamps were removed.Only 5%were detected at inception of bypass.Rates for embolization were 15.15 embolic signals per minute at crossclamp removal,10.9 embolic signals per minute at partial occlusion clamp removal and fewer than 3 embolic signals per minute at other times. Correlation was found between the number of emboli,severity of aortic atheromatosis,and neurocognitive deterioration.The majority of emboli detected during coronary artery bypass grafting are associated with the release of clamps.Clamp manipulation may lead to release of aortic atheromatous debris.These emboli may be relevant to neurocognitive outcome.
