Carotid endarterectomy can cause cranial and cervical nerve injuries, primarily transient. While most nerve injuries resolve, a small percentage may be permanent, necessitating long-term follow-up for delayed recovery.

Area of Science:

  • Neurology
  • Vascular Surgery

Background:

  • Carotid endarterectomy is a common procedure to prevent stroke.
  • Cranial and cervical nerve dysfunction is a potential complication.
  • Understanding the incidence and outcomes of these injuries is crucial.

Purpose of the Study:

  • To review the incidence and outcomes of cranial and cervical nerve dysfunction following carotid endarterectomy.

Main Methods:

  • Prospective study of 183 carotid endarterectomies.
  • Preoperative and postoperative cranial nerve assessments, including fiberoptic laryngoscopy.
  • Long-term follow-up for patients with neuropraxia.

Main Results:

  • 14.2% of patients (21/183) experienced nerve injuries.

  • Most common: recurrent laryngeal (14), hypoglossal (8).
  • 1.1% (2/183) had permanent injuries; 9.8% (18/183) were transient.

    • Conclusions:

    • Focal neuropraxia after carotid endarterectomy is relatively uncommon.
    • The majority of nerve injuries are transient.
    • Permanent injuries can cause significant disability, and extended follow-up is key for assessing delayed recovery.
