Clearly,TCD monitoring can be helpful in assessing the effect of CEA in removing the suspected source of cerebral microemboli.Ongoing microemboli to the brain should prompt reassessment of the operated carotid artery or a search for other potential sources of cerebral embolism.Carotid artery pulses seem to produce cerebral microemboli for a limited period,which implies that the prophylactic effect of CEA might decrease if the operation is delayed. |
