Cerebral hyperperfusion syndrome

From Wikipedia, the free encyclopedia

Cerebral hyperperfusion syndrome, also known as reperfusion syndrome, is a dysregulated state of cerebral blood flow following the restoration of arterial blood flow to the brain, usually following treatment of carotid artery stenosis.[1] Risk factors include hypertension, particularly high blood pressures in the first few days following revascularization and bilateral stenosis.

Symptoms

[edit]

The first symptom is usually severe headache, and a headache in the setting of recent carotid endarterectomy or carotid stenting should prompt a return to the hospital and close attention by clinicians. Symptoms may progress to seizures and coma in severe cases.

Treatment

[edit]

Treatment is control of the blood pressure, often with continuous intravenous antihypertensives medicines in the intensive care setting.[2] Seizures may require treatment with anti-seizure medication.
