Carotid endarterectomy impairs blood pressure homeostasis by reducing the physiologic baroreflex reserve

Carotid endarterectomy impairs blood pressure homeostasis through surgical destruction of the ipsilateral carotid baroreflex mechanism. Patients with contralateral carotid stenosis have a reduced baroreflex reserve and show greater baroreflex dysfunction and hemodynamic instability after endarterectomy. These patients are at greater risk of postendarterectomy complications and should be monitored closely.
