Is external carotid endarterectomy a durable procedure?

D F Fisher, R J Valentine, C B Patterson

    American Journal of Surgery
    |December 1, 1986
    PubMed
    Summary

    External carotid revascularization is a safe and effective treatment for patients with internal carotid occlusion and neurologic symptoms. Regular noninvasive testing is crucial for detecting recurrent stenosis and ensuring long-term success.

    Area of Science:

    • Vascular Surgery
    • Cerebrovascular Disease
    • Neurosurgery

    Background:

    • Internal carotid artery occlusion can lead to significant cerebrovascular events.
    • Symptomatic patients often require intervention to prevent stroke.
    • External carotid revascularization offers a potential therapeutic option.

    Purpose of the Study:

    • To evaluate the safety and durability of primary external carotid revascularization.
    • To assess the efficacy of this procedure in patients with internal carotid occlusion.
    • To determine the role of noninvasive testing in follow-up.

    Main Methods:

    • 14 primary external carotid revascularization procedures were performed on 13 patients.
    • Procedures included stump obliteration with patch angioplasty or vein bypass.

  • Patients underwent serial carotid noninvasive testing (ultrasonography, spectral analysis, oculoplethysmography).

    • Main Results:

    • 11 of 13 patients were symptomatic with transient ischemic attacks or amaurosis fugax.
    • Two patients developed recurrent stenosis, detected by noninvasive tests and successfully treated.
    • Mean follow-up was 22 months, demonstrating procedure durability.

    Conclusions:

    • External carotid revascularization is a safe and durable procedure for selected patients.
    • Periodic noninvasive carotid testing is essential for detecting recurrent stenoses.
    • This intervention is superior to other therapies for neurologic symptoms ipsilateral to internal carotid occlusion.
