The role of cardiopulmonary bypass technique in cerebral protection
Cardiopulmonary bypass is neccessary for most operations on the thoracic aorta, and optional for some cerebrovascular operations. In this context it is probable that the contribution of the bypass circuit itself to cerebral injury is small compared to the intrinsic risks imposed by the arterial pathology being treated. Particular patient related hazards for the brain include aortic atherosclerosis, flow limiting stenoses in extracranial and intra-cranial cerebral arteries, and previous cerebral infarcts.
