[Cervical root avulsion in metrizamide myelography]

H P Molsen, H Feldmann, R Lehmann

    Zentralblatt Fur Neurochirurgie
    |January 1, 1980
    PubMed
    Summary

    This study introduces Amipaque, a water-soluble contrast medium, as a superior alternative to Pantopaque for visualizing cervical root pockets after root avulsion. Amipaque allows for complete removal, improving diagnostic procedures for spinal nerve root visualization.

    Area of Science:

    • Neurology
    • Radiology
    • Medical Imaging

    Context:

    • Traditional methods for demonstrating cervical root pockets after root avulsion utilized Pantopaque, an oily contrast medium.
    • Pantopaque often remains in the cerebrospinal fluid space, posing challenges for complete removal.
    • This limitation necessitates exploring alternative, more easily removable contrast agents.

    Purpose:

    • To evaluate the efficacy of Amipaque, a water-soluble contrast medium, as a replacement for Pantopaque in visualizing empty cervical root pockets.
    • To describe the technical procedure for using Amipaque via lateral cervical fluid space puncture.
    • To compare the advantages of Amipaque over Pantopaque in diagnostic imaging of nerve root avulsion.

    Summary:

    • The study details a technique using Amipaque administered via lateral cervical fluid space puncture to visualize empty cervical root pockets.
    • The procedure involves specific patient positioning (lateral with pelvic elevation or prone for infants) to facilitate contrast medium flow into the pockets.
    • Tomography may be employed to enhance visualization, and the water-soluble nature of Amipaque allows for complete removal, unlike Pantopaque.

    Impact:

    • This research offers a safer and more effective imaging modality for diagnosing nerve root avulsion by utilizing a contrast agent that can be fully removed.
    • The described technique provides clinicians with a refined method for assessing spinal nerve root integrity.
    • The findings contribute to improved diagnostic accuracy and patient management in cases of traumatic nerve injury.
