Abstract
- Cerebral hyperperfusion syndrome is a rare but serious complication of carotid revascularization, and characterized by ipsilateral headache, hypertension, seizures, and focal neurological deficits. Therefore, treatment strategies are directed towards regulation of blood pressure and limitation of rises in cerebral perfusion to prevent cerebral edema or hemorrhage, especially during several days after carotid endarterctomy or stenting. We report the unique case of a patient who suffered from contralateral cortical subarachnoid hemorrhage after carotid artery stenting, despite of well-controlled blood pressure.
