Unlabelled: In spite of the progress made in diagnostic procedures and development of the operating rooms technology, considerable neurological deficit after operation of tumors localised in the brain motor zone commits one to direct intraoperative identification of the motor zone. By introducing direct electrocortical stimulation into the routine intraoperative application the primary goal has been achieved -reaching the maximum degree of radicalness of surgical resection while preserving motor centres in the cerebral cortex., Method: We are hereby demonstrating a series of 60 patients operated for primary brain tumors localised in the area in the front and around the central sulcus. All operations have been performed under the general anesthetics. During the operations the method of direct electrostimulation (ES) was used for the purpose of identifying motor centres., Results: Intraoperatively a level of subtotal resection was achieved in 22 cases, while radical resection was possible in 38 cases. Significantly higher level of radicalness of surgical resection of the low grade glioma tumor was confirmed statistically in relation to the group of patients with glioblastoma multiforme by applying the ES cortex (p < 0.05). Patients with slow developing brain glioma have statistically considerably higher KI value in relation to the KI values in the group of patients with glioblastoma multiforme (p 0 < 0.01). Difference in the measured values of distance from the coronal suture based on the results of MRI measuring and finding obtained by ES, has shown a statistically considerably higher difference with a glioblastoma multiforme 8.26 +/- 4.288 mm when compared to slowly developing astrocitoma 5.88 +/- 3,080 (p < 0.05)., Conclusion: Electrostimulation of the brain cortex is a safe, simple and precise method for identification of the brain motor zone which enables prevention of additional postoperative deficit and higher level of surgical radicalness.

Aneurysms on cerebral blood vessels due to their localization, size, relationship with neurovascular structures, even today, represent besides the constant progress of the diagnostic techniques and instruments in the operating theaters, a great therapeutic challenge. Gigantic aneurysms, aneurysms localized within the cavernous sinus and aneurysms of the vertebrobasilary confluence carry a great perioperative risk of mortality and morbidity. In fact, development of the endovascular procedures for the occlusion of their lumen made possible great progress in the treatment of aneurysms of this localization. In a not so small number of cases endovascular procedure means remodeling of the lumen of the main blood vessel. Endovascular obliteration of aneurysms has a certain advantage as regards the surgical treatment of aneurysms in which, on the basis of the expected natural course and presumed operative risk, may be judged that there exists unacceptably great operative risk. We present a personal series and results in 6 patients with aneurysms of various localizations.

In past, cavernoma was frequently cause of symptomatic epilepsy without pathological supstrat. We present the group of the patient (32) who illness were presented by epilepsy, and who were treated in Institut for Neurosurgery from 1998 to 2003. There is the good correlation between presentation of epilepsy and largness of the cavernoma (Phi 0.683). In 22 patinets the epilepsy was controlated by medicaments, and in other the seayurs were uncontrolled. Cavernoma initially presented with seayures had no inclination for massive intralesional or parenhimal bleeding. After surgical extirpation of leasion, there was good outcome during the following period of 3 years
