Computer-assisted neurosurgery using advanced imaging like MRI and CT scans allows for precise, minimally invasive treatment of brain conditions. This technology enables surgeons to access previously inoperable lesions with reduced risk.

Area of Science:

  • Neurosurgery
  • Medical Imaging
  • Computer-Assisted Surgery

Background:

  • Val-de-Grâce hospital established a stereotactic unit in 1988, integrating advanced imaging technologies.
  • Initial setup involved networked MRI and CT scanners for radiological use.

Purpose of the Study:

  • To develop and implement computer-assisted stereotactic techniques in neurosurgery.
  • To improve surgical precision and access to intracranial lesions.

Main Methods:

  • Integration of MRI and CT data for stereotactic planning.
  • Adaptation of stereotactic software (Leksell, Fisher, CRW) for MRI.
  • Development of data processing for MRI-based stereotactic biopsies.
  • Network expansion to radiotherapy for stereotactic irradiations.

  • Implementation of a computer-guided microscope (Zeiss MKM) for frameless stereotaxy.

    • Main Results:

    • Over 900 computer-guided stereotactic biopsies performed with millimeter precision since 1989.
    • 120 procedures utilizing the Zeiss MKM microscope with frameless stereotaxy since 1994.
    • Mean precision of 1.2 mm with cranial landmarks and 2.8 mm with scalp markers.

    Conclusions:

    • Computer-assisted neurosurgery significantly advanced the surgical approach to intracranial and intracerebral diseases.
    • Minimized risks and enabled access to previously inoperable lesions through smaller, precise surgical routes.
