    Summary
    This summary is machine-generated.

    High cervical percutaneous cordotomy is effective for intractable pain. This stereotactic technique accurately targets the spinothalamic tract, offering tailored pain relief with a low risk of persistent paresis.

    Area of Science:

    • Neurosurgery
    • Pain Management
    • Stereotactic Surgery

    Background:

    • Cordotomy is indicated for intractable pain unresponsive to conservative measures.
    • Non-dysaesthetic pain types are the primary candidates for cordotomy.
    • Stereotactic surgery principles enhance precision in lesion targeting.

    Purpose of the Study:

    • To evaluate the efficacy and safety of a high cervical percutaneous cordotomy technique.
    • To assess the accuracy of physiological localization of the spinothalamic tract.
    • To determine the incidence of adverse events, specifically persistent paresis.

    Main Methods:

    • Utilized a high cervical percutaneous approach for cordotomy.
    • Employed 100 Hz stimulation for physiological localization of the spinothalamic tract.

  • Focused on somatotopographic organization of responses to tailor analgesia.

    • Main Results:

    • Successfully located the spinothalamic tract in 99% of 264 consecutive procedures.
    • Achieved precise targeting through physiological localization.
    • Reported a low incidence of significant persistent paresis at 0.3%.

    Conclusions:

    • High cervical percutaneous cordotomy is a precise method for intractable pain management.
    • The technique allows for tailored analgesia based on somatotopic mapping.
    • This approach demonstrates a high success rate and minimal risk of neurological deficit.
