This study presents a modified computed tomography (CT) method for functional stereotaxis, improving visualization and coordinate accuracy. The technique demonstrated effectiveness in treating movement disorders and epilepsy, offering advantages over older methods.

Area of Science:

  • Neurosurgery
  • Medical Imaging
  • Neurology

Background:

  • Functional stereotaxis is a neurosurgical technique used for treating movement disorders and epilepsy.
  • Accurate targeting of brain structures is crucial for successful functional stereotactic operations.
  • Traditional methods like ventriculography have limitations in precise localization and control.

Purpose of the Study:

  • To describe a modified approach for visualizing and constructing coordinates in computed tomography (CT)-guided functional stereotaxis.
  • To evaluate the efficacy and advantages of this modified CT-based method in clinical practice.

Main Methods:

  • Development of a modified visualization and coordinate construction technique for stereotactic objects using CT.
  • Application of the method in four functional stereotactic operations: parkinsonian tremor (2), retrocollis (1), and epilepsy (1).

  • Post-operative CT examinations to evaluate lesion size and characteristics after coagulation therapy.

    • Main Results:

    • The modified CT-based method was successfully applied in four diverse functional stereotactic cases.
    • Post-operative CT scans allowed for the evaluation of lesion characteristics and size.
    • The authors observed advantages of CT control compared to previous ventriculography techniques.

    Conclusions:

    • The described modification enhances the visualization and coordinate accuracy for CT-controlled functional stereotaxis.
    • CT offers superior control and evaluation capabilities for functional stereotactic operations compared to ventriculography.
    • This technique shows promise for improved outcomes in neurosurgical interventions for movement disorders and epilepsy.
