[Stereotaxic biopsy of brain tumor using computer tomography].

The work discusses the results of the clinical application of a modified method of stereotaxic biopsy of deeply located brain gliomas according to the results of computer tomography. In some patients with gliomas of subcortical localization stereotaxic biopsy was combined with cryodestruction of the tumour. The method makes it possible to extend the possibilities for precise diagnosis of deeply located three-dimensional processes in the brain, to clearly define the limits of their operability and to cause an effect on them by means of the cryosurgical method.
