Abstract:
The so-called cerebral hyperperfusion syndrome is basically due to a lack of cerebral autoregulation, inability to control the restoring of flow after revascularisation surgery. It present clinically as intense migraine, epileptic seizures, or neurological focality. It may even progress to an intracerebral haemorrhage. It usually appears a few days after surgery. We present the case of a patient subjected to a carotid endarterectomy, who had an epileptic episode in the late post-operative period. We attributed a cerebral hyperperfusion syndrome as the most likely cause. Knowledge of this syndrome may help to correctly orientate and treat the neurological complications that appear after this type of surgery.
