[Craniovertebral intradural meningiomas: analysis of postoperative outcomes (a retrospective two-center study)].

Objective: To analyze the postoperative outcomes in patients with craniovertebral meningiomas with preoperative justification of surgical approach depending on tumor localization.

Material And Methods: We examined 36 patients with craniovertebral meningiomas. The Karnofsky, Frankel and cranial nerve dysfunction scales were used to assess functional status of patients.

The new algorithm for stratification of the risk of venous thromboembolic events in elective neurosurgery and its prognostic significance.

Unlabelled: Early identification of risk groups is essential for effective and target prevention of venous thromboembolic events (VTE) in all areas of surgery. For this purpose, the authors has developed and put into practice an algorithm distinguishing the groups of low, moderate and high risk of VTE among neurosurgical patients.

Objective: To assess predictive value of the developed algorithm for elective neurosurgical interventions.

[Olfactory (subfrontal) schwannoma: case report and literature review].

Background: Olfactory nerve schwannomas are extremely rare. Their origin is still unclear, since olfactory nerve has no Schwann cells. There are about 70 case reports of olfactory nerve schwannoma in the world literature.

[Invasive EEG for temporal lobe epilepsy: selection of technique].

Background: Non-invasive EEG reveals epileptogenic zone in 70% of patients. In other cases, invasive EEG monitoring is indicated. Various implantation strategies and techniques of intracranial EEG (icEEG) potentially provide different outcomes.
