Case Reports[The results of applying the system of neuronavigation in the intracranial surgery].
Frameless stereotactic techniques combined with a high-resolution neuro-imaging made its possible for us to perform, with high reliability, interactive image-guided procedures. We used the Carl Zeiss Surgical Microscope Navigator System with Carl Zeiss OPMI NC-4 microscope. We reported our results on the first 82 patients during the 20-month period. 36 were males (44%), 46--females (56%) with the age range of 15 to 79 (mean 43.43). ⋯ There were no significant technical problems. The clinical and surgical results were satisfying in all cases. 14 patients with secondary epilepsy, as the only symptom, were postoperatively seizure-free. Neuronavigation cuts the time of surgery and ensures a more radical resection of pathological tissue with lower mortality and morbidity thus improving the life quality of patients.

[Evaluation of the capacities of neurophysiological intraoperative monitoring in reconstructive surgery on the vertebral column].
To evaluate the capacities of neurosurgical intraoperative monitoring of somatosensory evoked potentials (SSEP) in reconstructive operations on the vertebral column. ⋯ 1. Neurophysiological intraoperative monitoring yields additional information for surgeons during an operation. 2. During intraoperative monitoring of SSEPs, it is necessary to assess any changes in the latter as true and to immediately find possible causes of these changes. 3. In patients with revealed spondylogenic spinal circulatory disorders and severe neurological disorders, even short-term changes in SSEPs should be assessed with particular carefulness before surgery.

Clinical Trial[Temporary arterial clipping in surgery for cerebral aneurysms in acute subarachnoidal hemorrhage].
Temporary clipping was used during operations in 69 patients. Of them, 51 patients underwent temporary arterial clipping, forced temporary arterial clipping was used in 18 patients. ⋯ The bioelectrical activity of the brain was intraoperatively monitored by using EEG and ECG in 12 patients of whom 11 felt rather well on discharge. The temporarily arterial clipping technique using EEG and ECG makes it possible to monitor the allowable time of temporary arterial clipping, which is in turn associated with a less risk for postoperative ischemic complications.

Clinical Trial[Experience with endovascular occlusion of cerebrovascular aneurysms by means of microspirals].
The paper summarizes the outcomes of endovascular treatment of 42 patients (19 males and 23 females) aged 24 to 68 years who had cerebrovascular aneurysms, 7 of them were operated on in the acute phase of subarachnoidal hemorrhage. There were small [n = 27 (61.4%)], large [n = 14 (31.8%)], and giant [n = 3 (6.8%)] aneurysms. According to their site, aneurysms were found in the internal carotid [n = 22 (50%)], the middle cerebral artery [n = 2 (4.5%)], the anterior cerebral artery-anterior communicating artery [n = 10 (22.7%)], the basilar artery [n = 9 (20.5%)], and the vertebral artery [n = 1 (2.3%)]. ⋯ With subtotal or partial occlusion, there was a change in the position of spiral coils in the aneurysmal cavity, namely, their displacement to the bottom and an increase in the dimension of a functioning aneurysmal part (2 patients). The use of microspirals for occlusion of cerebrovascular aneurysms is a low-traumatic and effective treatment. The best results were obtained with the occlusion of small and large aneurysms with their well-defined neck.

Case Reports[Massive recurrent venous air embolism in a patient with brain stem cavernoma undergone surgery in the sitting position (a case report)].
The paper outlines a rare clinical case of cavernous angioma of the brain stem in a female who was operated on in the sitting position and who intraoperatively developed 6 episodes of massive venous air embolism in tandem from the transverse sinus defect undetectable by the cervical vein compression test. Why it is difficult to diagnose this complication in this case is considered. Preventive and therapeutical measures are given.
