Cranial nerve injuring during carotid endarterectomy

Area of Science:

• Neurosurgery
• Vascular Surgery
• Anatomy

Background:

• Carotid endarterectomy (CEA) is a common procedure to remove plaque from carotid arteries.
• Cranial nerve injury is a known complication during CEA, potentially leading to significant morbidity.

Observation:

• The greater auricular, hypoglossal, and superior laryngeal nerves are at risk during CEA.
• Understanding the precise anatomical location and potential injury mechanisms is crucial.

Findings:

• Nerve injury during CEA is preventable through meticulous surgical technique and regional anatomical awareness.
• While isolated unilateral nerve injuries are often tolerated, bilateral or combined injuries present life-threatening risks.

Implications:

• Implementing minor technical modifications during CEA can significantly reduce the incidence of nerve-related complications.
• Enhanced anatomical knowledge and surgical precision are key to improving patient outcomes and preventing serious morbidity after CEA.
