    Summary
    This summary is machine-generated.

    Transcallosal surgery in children can lead to disjunctive syndromes if cerebral hemisphere lesions are present. These syndromes involve memory loss and motor disturbances, impacting surgical approach suitability.

    Area of Science:

    • Neurosurgery
    • Neurology
    • Pediatric Surgery

    Background:

    • Transcallosal surgery involves accessing brain structures through the corpus callosum.
    • Potential sequelae of corpus callosum transection require clinical assessment.
    • Understanding the impact of isolated vs. accompanied lesions is crucial.

    Purpose of the Study:

    • To clinically assess the sequelae of transcallosal surgery in pediatric patients.
    • To identify neurological deficits associated with isolated corpus callosum transection.
    • To evaluate the suitability of the transcallosal approach based on lesion location.

    Main Methods:

    • Clinical assessment of 15 children undergoing transcallosal surgery.
    • Evaluation of neurological function, focusing on memory and motor skills.

  • Correlation of surgical approach with lesion location and resulting deficits.

    • Main Results:

    • Isolated corpus callosum transection without cerebral hemisphere lesions shows minimal pronounced deficits.
    • Disturbances in cerebral centers, particularly the proprioceptive analyzer, can lead to memory loss, hypokinesia, ideomotor apraxia, and astereognosia.
    • The observed symptoms are mixed, suggesting disjunctive syndromes.

    Conclusions:

    • Transcallosal surgery is suitable for lesions in the anterior parts of the third and lateral ventricles.
    • The presence of cerebral hemisphere lesions significantly influences the neurological sequelae after transcallosal surgery.
    • Careful patient selection and assessment are vital to minimize adverse outcomes.
