Abstract
Abstract: Cerebral hyperperfusion syndrome (CHS) is a complication that follows carotid artery revascularization by either carotid endarterectomy or carotid artery stenting. CHS typically presents with a triad of signs and symptoms including throbbing headache; focal neurologic deficits such as unilateral paresis, visual disturbance, or dysarthria; and seizures. Because CHS can result in significant morbidity and mortality, anticipation, early recognition, and aggressive management are essential to prevent disastrous complications such as intracerebral hemorrhage.1
