    Elective carotid artery resection significantly improves survival rates compared to emergency surgery. The ocular plethysmograph (OPG) may accurately predict patient tolerance for carotid artery loss, aiding surgical planning.

    Area of Science:

    • Vascular Surgery
    • Neurology
    • Medical Diagnostics

    Background:

    • Carotid artery resection carries high mortality, especially during emergencies.
    • Elective resection shows better survival rates, highlighting the need for predictive tools.
    • Assessing collateral blood flow is crucial for predicting tolerance to carotid artery loss.

    Purpose of the Study:

    • To evaluate the ocular plethysmograph (OPG) as a tool for predicting tolerance to carotid artery resection.
    • To determine if OPG can accurately assess collateral hemispheric blood flow.

    Main Methods:

    • Retrospective analysis of carotid artery resection outcomes.
    • Prospective evaluation of eleven patients using the ocular plethysmograph (OPG).
    • Correlation of OPG predictions with actual surgical outcomes.

    Main Results:

    • Emergency carotid artery resection had a 64% mortality rate versus 14% for elective procedures.
    • OPG predicted successful resection tolerance in nine out of eleven patients.
    • Four patients underwent resection without neurological complications, aligning with OPG predictions.

    Conclusions:

    • Elective carotid artery resection is associated with significantly better outcomes.
    • The ocular plethysmograph (OPG) shows promise as a non-invasive method to predict tolerance for carotid artery resection.
    • OPG may help optimize surgical planning and improve patient outcomes in carotid artery surgery.
