Duplicate origin of left vertebral artery.

S Suzuki, Y Kuwabara, R Hatano

    Neuroradiology
    |March 29, 1978
    PubMed
    Summary

    A rare case of a duplicated left vertebral artery originating from the aortic arch was found alongside a large aortic aneurysm. This anatomical variation involves an aberrant artery joining the normal one in the neck.

    Area of Science:

    • Vascular anatomy
    • Cardiovascular research
    • Anatomical variations

    Background:

    • The vertebral arteries are crucial for supplying blood to the brain.
    • Variations in their origin can impact surgical planning and diagnostic interpretation.
    • Aortic arch aneurysms pose significant clinical risks.

    Observation:

    • A verified case of a duplicated left vertebral artery was identified.
    • This anomaly was associated with a large aneurysm of the aortic arch.
    • The aberrant left vertebral artery originated directly from the aortic arch, between the left common carotid and left subclavian arteries.

    Findings:

    • The anomalous left vertebral artery merged with the normal left vertebral artery within the transverse foramen of the fifth cervical vertebra.
    • This duplication represents a rare congenital vascular variation.
    • The coexistence with an aortic arch aneurysm highlights potential complex pathologies.

    Implications:

    • Understanding such anatomical variations is vital for neurovascular and cardiothoracic surgery.
    • Accurate imaging and diagnosis are critical for managing patients with these anomalies.
    • This case contributes to the literature on vertebral artery origins and aortic pathologies.
