[Stereotactic radiosurgery in neurosurgery].
Gamma-knife stereotactic radiosurgery offers a broad spectrum armamentarium for the safe treatment of various lesions within the central nervous system. It is widely used for treatment of metastastic brain tumors, non respectable tumours, residual or recurrent benign and malignant tumors as well as for treatment of arteriovenous malformations, functional diseases and pain disorders. It is less invasive than most other surgical methods and also cost effective compared to surgical methods and other radiation treatments.
