[Malignant cerebellar infarction: clinical course and surgical treatment].

Aim: To clarify the indications for surgical treatment of malignant cerebellar infarction (CI).

Material And Methods: Eighty patients with CI were studied. The malignancy of CI was understood as the development of mass effect in the posterior cranial fossa, accompanied by the decrease in consciousness due to compression of the brain stem and/or the development of occlusive hydrocephalus.

[Endovascular treatment of tandem occlusion of internal carotid and middle cerebral arteries in acute ischemic stroke].

The paper presents the literature data concerning the results and surgical approaches to the treatment of tandem occlusion in the ICA system. The authors describe two clinical cases of endovascular treatment of tandem ipsilateral occlusion of ICA and middle cerebral artery (MCA). In both cases, the cause of two-level occlusion was complicated by thrombosis atherosclerotic plaque in ICA in the extracranial part with distal thromboembolism in SMA.

[Surgical treatment of cerebral aneurysms in the Russian Federation].

Objective: The objective of this study was to evaluate the results of surgical treatment of cerebral aneurysms in the Russian Federation.

Material And Methods: We analyzed performance indicators in neurosurgical departments of regional and federal health institutions of the Russian Federation for 2017. The results of surgical treatment of cerebral aneurysms (CAs) were analyzed in 19 regional vascular centers (RVCs) in several federal districts and in 3 federal centers (FCs) with the most dynamically developing vascular neurosurgery and smoothly running system of statistical data processing.

[Posttraumatic seizures: a prospective cohort study].

Aim: To evaluate the incidence and risk factors for posttraumatic seizures (PTS).

Material And Methods: The authors conducted a prospective study of 237 patients with TBI of varying severity. The patients were hospitalized and examined in Moscow neurosurgery departments.

[Diagnosis and treatment of extracranial internal carotid artery lesion combined with cerebrovascular malformation].

Aim: To analyze own experience of diagnosis and treatment of patients with extracranial internal carotid artery lesion and cerebrovascular malformations.

Material And Methods: There were 16 patients with combined lesion of extracranial and intracranial internal carotid artery for the period January 2013 - December 2014. Occlusive-stenotic lesion and tortuosity of ICA were observed in 11 and 5 cases respectively.

[Early reconstruction of brachiocephalic arteries as a prevention of recurrent ischemic stroke].

Aim: To assess an efficacy and safety of brachiocephalic arteries reconstruction at the acute stage of stroke.

Material And Methods: Early reconstruction of brachiocephalic arteries was made in 7 patients (mean age 67±9 years). Mean terms of brachiocephalic arteries reconstruction after stroke were 4.

[Early reconstruction of supra-aortic vessels as a prevention of recurrent ischemic stroke].

Aim: To evaluate the efficacy and safety of supra-aortic vessels reconstruction within acute period of stroke.

Material And Methods: Early surgery was performed in 7 patients aged 67±9 years. Revascularization was made after 4.

[Stenosis of the vertebral canal in the lower spine].

The article reviews modern literature on the pathophysiology and clinical signs of degenerative stenosis of the lower spine. Possibilities of modern instrumental diagnosis and the differential clinical diagnosis of lumbar stenosis are presented. A modern treatment tactics and indications for surgical treatment are described.

[MONITORING OF INTRACRANIAL PRESSURE IN PATIENTS WITH MASSIVE ISCHEMIC STROKE].

Purpose Of The Study: To assess the role of monitoring of intracranial pressure (ICP) in patients with massive ischemic stroke within the first 5 days of the onset of the disease.

Material And Methods: We have analyzed the results of monitoring of intracranial pressure in 10 patients with massive ischemic stroke and compared dynamics of ICP with the dynamics of intracranial pressure and the level of consciousness and dislocation of the brain according to CT RESULTS: Dislocation syndrome decompensation occurred in 6 patients, of which only 3 patients had increased intracranial pressure greater than 20 mm Hg with oppression of the level of consciousness to moderate coma and deeper The average value of transverse dislocation in these patients at the same time amounted to 17 mm. In 2 patients with atrophy of the brain we observed ICP increase over 20 mmHg.

[Dislocation syndrome in patients with severe massive ischemic stroke].

Objective: To compare the severity of brain dislocation, the rate of its progression according to CT results and clinical signs of dislocation syndrome (DS) in patients with unfavorable form of massive ischemic stroke (MII).

Material And Methods: We analyzed the results of examination and treatment of 114 patients with unfavorable course of MII. Patients were stratified by the type of DS course into two groups: group 1 with unfavorable course (91 patients) and group 2 with favorable course (23 patients).

[Hyperdensivity of the trunk of the middle cerebral artery on the CT scanning in the acute stage of ischemic stroke].

Twenty-nine patients with massive ischemic stroke (MIS) admitted to the hospital in the first 12h after stroke were examined. On the primary CT scan, there were no zones with decreased density of brain matter. A subsequent CT was performed on the next day to visualize stroke lesions.
