[Cryosurgical treatment of tumors of the cerebral hemispheres].

A technique of cryosurgical removal of extra- and intracerebral tumours of the hemispheres of the brain was developed. The employed cryosurgical device was provided with a cryoprobe featuring an instrument fixed in a handle and having a vacuum-insulated line of supply and removal of the cold-carrying agent (liquid nitrogen). The separation of the tumour from the surrounding brain tissue and the control of haemorrhage from the cerebral vessels was performed with the aid of a cryocoagulator connected with the cryosurgical device. An analysis of 64 cryosurgical interventions demonstrated that the employment of the cryosurgical method helps to prevent cerebrovascular disorders, and to decrease the degree of brain oedema-swelling.
