About the specialty

Gamma Knife is a stereotactic radiosurgery technique: many beams converge on a small target in the brain, without any incision.

The indication is decided by the neurosurgery and radiotherapy team. Polycrabat Sevamed reviews the file and coordinates the referral and the stay.

Main conditions treated

  • Certain brain metastases
  • Certain meningiomas
  • Certain vascular malformations
  • Trigeminal neuralgia depending on the indication
  • Small benign tumours
  • Situations decided at a multidisciplinary meeting

Tests, techniques and procedures

The techniques used and their indication are decided by the doctor, case by case. As a general guide:

  • Analysis of the file and imaging
  • Imaging to locate the target
  • Treatment planning
  • Follow-up imaging

Depending on the medical indication, the technique concerned is offered within the Polycrabat Sevamed network. Its availability in a specific facility is confirmed by the coordination team on a case-by-case basis.
