Cerebral hyperperfusion syndrome following carotid artery revascularization

Abstract

In Brief 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 Cerebral hyperperfusion syndrome (CHS) is a complication that follows carotid artery revascularization by either carotid endarterectomy or carotid artery stenting. Anticipation, early recognition, and aggressive management of CHS are essential to prevent disastrous complications.
