Dysplastic vertebral artery with paradoxical infarction

B Curry, A A Sima

    The Canadian Journal of Neurological Sciences. Le Journal Canadien Des Sciences Neurologiques
    |November 1, 1980
    PubMed
    Summary

    A rare vertebral artery anomaly, characterized by multiple channels and associated vascular conditions, was identified in a 63-year-old male. This case highlights potential embryological origins of complex cerebrovascular malformations.

    Area of Science:

    • Vascular anatomy
    • Embryology
    • Neuropathology

    Background:

    • Vertebral artery anomalies are uncommon and can predispose individuals to cerebrovascular events.
    • Understanding the embryological basis of vascular malformations is crucial for diagnosis and management.

    Observation:

    • A rare anomaly of the right vertebral artery was observed, presenting as multiple minute endothelial-lined channels that did not perfuse.
    • Associated findings included muscular media dysplasia in the anterior spinal artery and large posterior communicating arteries.

    Findings:

    • The patient's terminal event was caused by thrombotic occlusion of the left vertebral artery.
    • The described vascular anomalies suggest a complex developmental process originating during embryogenesis.

    Implications:

    • This case underscores the importance of recognizing rare vertebral artery variations in clinical practice.
    • Further research into the embryological development of these anomalies may improve diagnostic and therapeutic strategies for cerebrovascular diseases.
