    Summary

    Intraoperative sonography during lumbar laminectomy is feasible and advantageous. This imaging technique allows visualization of the spinal canal anterior to neural structures, improving surgical exploration.

    Area of Science:

    • Neurosurgery
    • Medical Imaging
    • Spinal Surgery

    Background:

    • Lumbar laminectomy is a common spinal decompression procedure.
    • Direct visualization of the anterior spinal canal is limited during posterior approaches.
    • Intraoperative imaging can enhance surgical precision and safety.

    Purpose of the Study:

    • To assess the feasibility of using intraoperative sonography during lumbar laminectomy.
    • To evaluate the advantages of sonography for visualizing the spinal canal.
    • To determine the potential contribution of this technique to surgical localization.

    Main Methods:

    • Sonography was performed during lumbar laminectomy in six patients.
    • A warm saline water bath was utilized as an acoustic window.
    • Standard surgical approaches were employed for laminectomy.

    Main Results:

    • Intraoperative sonography was successfully demonstrated in all six cases.
    • The technique provided clear visualization of the spinal canal anterior to the spinal cord and cauda equina.
    • The posterior operative approach does not allow direct visualization of these anterior structures.

    Conclusions:

    • Intraoperative sonography is a feasible technique during lumbar laminectomy.
    • Sonography offers a significant advantage by imaging anterior spinal structures.
    • This method enhances intraoperative exploration and localization during spinal surgery.
