Transcranial Doppler in the Study of Cerebral Perfusion During Cardiopulmonary Bypass

  • T. Lundar


Studies of the cerebral circulation during cardiopulmonary bypass (CPB) procedures have been severely hampered by methodological difficulties. Compared with the large numbers of cardiac operations performed each year, knowledge on cerebral perfusion has been remarkably scarce, especially since cerebral damage remains a major and devastating com-plication of cardiac surgery [5]. Early experimental studies using electromagnetic carotid artery flowmetry, indicated that carotid flow fluctuated passively with flow from the heart-lung machine during non-pulsatile cardiopulmonary bypass [4, 7].
