[Cryosurgical method in functional stereotactic neurosurgery].

Method of cryodestruction of deep subcortical structures is used in functional stereotactic operations in patients with chronic progressing diseases of the central nervous system. The PAH device produces cooling the tissues in the target point of the brain to -70 degrees C, which allows to obtain the destruction focus with volume 0.2 or 1 cm3. The source of cooling in the apparatus is solid cryodestruction carbonic acid. The method was used in 352 patients. The results of operations showed high degree of repeatability of geometric parameters of the obtained foci in the target structures, as well as the absence of the general and pronounced local tissue reaction to the cryodestruction foci. There was low percentage of hemorrhagic and infectious complications.
