    Summary

    Emergency carotid endarterectomy is effective for stroke prevention. This study shows high rates of improvement in patients with severe stenosis, occlusion, or intraluminal defects, with low mortality.

    Area of Science:

    • Neurosurgery
    • Vascular Surgery
    • Neurology

    Background:

    • Carotid endarterectomy is a surgical procedure to remove plaque from the carotid artery.
    • Emergency indications for carotid endarterectomy are less well-defined than elective procedures.
    • Understanding outcomes of emergency carotid endarterectomy is crucial for patient management.

    Purpose of the Study:

    • To evaluate the outcomes of emergency carotid endarterectomy.
    • To correlate preoperative angiographic findings and clinical status with postoperative outcomes.
    • To discuss the indications for emergency carotid endarterectomy.

    Main Methods:

    • Retrospective review of 64 emergency carotid endarterectomies performed between July 1976 and December 1985.
    • Analysis of patient demographics, angiographic findings, and pre- and postoperative clinical status.
    • Categorization of clinical status into five grades: intact, mild, moderate, severe deficit, and death.

    Main Results:

    • High postoperative improvement rates were observed across different angiographic findings: 93% for severe stenosis, 73% for stenosis with intraluminal defects, 88% for complete occlusion, and 80% for moderate to severe stenosis/ulceration.
    • Patients with preoperative intact or mild deficits had a 92% improvement rate with no deaths.
    • Patients with moderate and severe deficits showed improvement in 80% and 77% of cases, respectively, with some mortality.
    • Overall mortality was low (4 deaths), with causes attributed to cardiac or unrelated disease.

    Conclusions:

    • Emergency carotid endarterectomy demonstrates favorable outcomes, particularly in patients with severe stenosis or occlusion.
    • The procedure appears safe and effective for selected patients presenting with acute neurological deficits.
    • Clinical and angiographic assessment is vital for determining eligibility and predicting outcomes in emergency settings.
