[Cryodestruction in neurosurgery].

The study aimed to work out the method of cryodestruction of brain tumors. 10 patients with neuroepithelial brain tumors were prospectively operated on with the use of cryodestruction. MRI was performed before and after the operation. The operation strated from tumor biopsy under the ultrasound control with further injection of cryoprobe with further destruction. The study demonstrated that ultrasound navigation is an effective means of the cryodestruction control on all stages. The cryodestruction itself is a miniinvasive, easily controlled and effective method, applicable for tumors, located in functionally important regions of the brain, where major surgery could be mutilating.
