    Area of Science:

    • Vascular Surgery
    • Cerebrovascular Disease
    • Neurosurgery

    Background:

    • Carotid endarterectomy (CEA) is a crucial procedure for preventing stroke in patients with symptomatic carotid artery disease.
    • Traditional CEA techniques often involve intraoperative monitoring and shunting to ensure cerebral perfusion.
    • There is ongoing debate regarding the necessity of these adjuncts for patient safety.

    Purpose of the Study:

    • To evaluate the safety and efficacy of CEA performed without indwelling shunts or electroencephalographic (EEG) monitoring.
    • To determine the stroke and mortality rates associated with this simplified CEA technique.

    Main Methods:

    • A retrospective review of 280 consecutive CEAs performed on 222 patients.
    • Patients were managed under general anesthesia with induced moderate hypertension for cerebral protection.

  • Carotid occlusion times averaged 10 minutes, with no routine use of shunts or EEG.

    • Main Results:

    • No operative mortality within 30 days post-procedure.
    • Zero strokes occurred during carotid artery occlusion.
    • A low incidence of stroke (1.1%, 3 patients) was observed within one month of surgery.
    • 93% patient follow-up was achieved, confirming long-term data availability.

    Conclusions:

    • CEA can be safely performed without the need for indwelling shunts or EEG monitoring.
    • General anesthesia and moderate hypertension provide adequate cerebral protection during CEA.
    • This approach simplifies the surgical procedure while maintaining excellent patient outcomes.
