Area of Science:

  • Neurosurgery
  • Medical Imaging
  • Computer-Aided Surgery

Background:

  • Modern computer technology enhances stereotactic biopsy planning.
  • It allows examination of the entire trajectory, not just the target point.

Purpose of the Study:

  • To evaluate the safety and efficacy of computer graphics workstations in stereotactic biopsies.
  • To assess the impact of detailed trajectory planning on biopsy outcomes.

Main Methods:

  • Two hundred consecutive stereotactic biopsies were performed by a single surgeon.
  • A computer graphics workstation was utilized for planning, scrutinizing target, entry, and trajectory.
  • Adjustments were made to minimize potential complications.

Main Results:

  • Pathologically abnormal tissue was obtained in 98.5% of cases (197/200).
  • No mortality was observed in the series.
  • Symptomatic hemorrhages occurred in 2% of cases (4/200).

Conclusions:

  • Computer graphics workstations are valuable tools for stereotactic biopsies.
  • They facilitate safe and effective tissue acquisition in diverse brain regions.
  • This technology enhances precision and safety in neurosurgical interventions.
