Progressing stroke. Angiographic aspects.

O W Houser, C H Millikan, C B Holman

    Acta Radiologica. Supplementum
    |January 1, 1976

    Summary

    Progressing strokes occurred in 17 patients undergoing surgery for internal carotid artery atheromatous disease. This neurological deficit progression over 18-24 hours suggests embolization and collateralization mechanisms.

    Area of Science:

    • Neurology
    • Vascular Surgery

    Background:

    • Atheromatous disease of the internal carotid artery poses a risk for cerebrovascular events.
    • Surgical intervention is a common treatment for severe carotid artery disease.

    Observation:

    • 17 out of 256 patients (6.6%) developed progressing strokes post-operatively.
    • These strokes were defined by an active increase in neurological deficit over 18-24 hours.

    Findings:

    • Angiography was not consistently specific but revealed key vascular mechanisms.
    • Embolization to cerebral leptomeningeal vessels was implicated.
    • Collateral circulation through these vessels also played a role.

    Implications:

    • Understanding these mechanisms can refine surgical strategies for carotid artery disease.
    • Further research into embolization and collateral flow may improve stroke prevention in these patients.
    • This study highlights a specific complication pattern in carotid artery surgery.
