Bilateral hypoglossal nerve injury after bilateral carotid endarterectomy

JA Gutrecht and HR Jones Jr
Department of Neurology, Lahey Clinic Medical Center, Burlington, MA 01805.

A case of severe bilateral injury to the hypoglossal nerves after two- stage carotid endarterectomy is described. Injury to the hypoglossal nerve occurs in up to 20% of patients undergoing carotid endarterectomy and may result in mild or unnoticed deficits. These injuries must be carefully searched for in patients who will undergo a similar procedure on the opposite side since a bilateral deficit of the hypoglossal nerve is poorly tolerated, causing potentially serious impairment of speech and risk of aspiration.
