[The biopsy of brain structures in patients with extrapyramidal hyperkinesia].

A new device for brain biopsy is presented, the techniques and method of biopsy of brain structures are described which allow full value biopsy material to be obtained from any area of the brain with minimal risk for the patient and high accuracy of hitting the aim. Biopsy of the cerebral and cerebellar cortex, and thalamic and cerebellar nuclei was conducted in 82 patients during stereotaxic operations (34 patients with infantile cerebral paralysis, 8 with torsion dystonia, 8 with spasmodic torticollis). Stereotaxic biopsy of brain tumors of various localization was also performed in 20 patients.

[Our experience with 2220 stereotaxic operations].

The article deals with the results of 2,220 stereotaxic operations carried out on 1,812 patients with various diseases of the central nervous system: 1,286 operations in parkinsonism, 439 in cerebral infantile paralysis, 150 in torsion dystonia (dystonia musculorum deformans), etc. The best results were produced in parkinsonism and dystonia musculorum deformans.

[Stereotaxic operations in the treatment of patients with infantile cerebral palsy].

The main neurosurgical forms of infantile cerebral palsy (ICP) are singled out: athetosis-torsional-dystonic, athetosis-spastic, athetosis-torsional-choreatic. Results of 273 stereotaxic operations in 163 ICP patients are analyzed. The best results were observed in with athetosis-choreatic and athetosis-torsional-dystonic forms that were associated with rigidity-spasticity.

[Stereotaxic surgery in infantile cerebral palsy].

The article analyses the results of 439 stereotaxic operations performed on 326 patients with the spastic-hyperkinetic form of infantile cerebral paralysis (ICP). Differentiated destructions of the brain structures were conducted. Extended thalamotomy, sagittal thalamotomy, and combined (cross) thalamodentatotomy were the most frequent complexes of destructions.

[Results of stereotaxic operations in patients with neurosurgical pathology].

The results of 2233 stereotaxic operations in 1812 patients are presented. Of them, 1286 were performed for parkinsonism, 439--for infantile cerebral paralysis, 150--for deforming muscular dystonia, 125--for epilepsy, 64--for neuro-oncological pathology, 169--for other diseases of the central nervous system. The best results were obtained in parkinsonism and deforming muscular dystonia.
