Area of Science:

  • Neurosurgery
  • Medical Imaging
  • Histopathology

Context:

  • Stereotactic neurosurgery requires precise targeting for biopsies and interventions.
  • Traditional methods can involve multiple punctures and potential complications.
  • Advancements in CT (Computed Tomography) and angiography aid in pre-procedural diagnosis and planning.

Purpose:

  • To present a novel stereotactic brain biopsy method enhancing accuracy and efficiency.
  • To reduce the number of punctures required for histological evaluation.
  • To facilitate minimally invasive therapeutic interventions in the brain.

Summary:

  • A new stereotactic brain biopsy method is detailed, utilizing CT-scanner (Somatom DRG) for marking needle tracks.
  • Local anesthesia is used during trephination in the operating theatre.

  • A stereotactic device, fixed to the patient's head, allows precise measurement (accuracy +/- 5 mm) of puncture direction and depth using CT scans.
  • A Teflon-sleeve guides instrumentation, enabling artifact-free tomograms, localization control, and multiple biopsy probes without repeat punctures.
  • The method also supports therapeutic interventions.

    • Impact:

    • This technique improves the accuracy of brain biopsies, leading to better diagnoses.
    • Minimizes patient trauma by reducing the need for repeated punctures.
    • Offers a versatile platform for both diagnostic sampling and therapeutic interventions in neurosurgery.
    • Potential for improved patient outcomes through more precise and less invasive procedures.
