[Treatment of acute tandem occlusion of arteries of anterior cerebral circulation without emergency stenting].

Unlabelled: The article deals with problems of endovascular treatment of acute tandem and isolated occlusions of arteries of the anterior cerebral circulation, as well as the problem of reocclusions and new occlusions of these target arteries in the early postoperative period after thrombectomy.

Purpose: To determine the effect of reocclusions and new, previously not identified occlusions of the carotid artery and middle cerebral artery after cerebral thrombectomy on the outcomes of ischaemic stroke, as well as to substantiate feasibility of endovascular policy without simultaneous carotid stenting in thrombectomy in case of tandem occlusions of arteries of the anterior cerebral circulation.

Patients And Methods: We studied the results of endovascular treatment of 52 patients with acute ischaemic stroke, including 26 patients with combined occlusions of the internal carotid and middle cerebral arteries (group 1) and 26 patients with isolated occlusion of the M1 segment of the middle cerebral artery or its equivalent (group 2).

[Clinical and neuroimaging heterogeneity of dementia with Lewy bodies].

Aim: To study clinical characteristics of dementia with Lewy bodies (DLB) depending on neuropsychological, neuroimaging and concomitant cerebrovascular changes as well as on the character of disease onset.

Material And Methods: Forty-five patients with DLB (25 men and 20 women, men age 72.9±7.

[Cerebral amyloid angiopathy].

Cerebral amyloid angiopathy (CAA) is characterized by the deposition of Β-amyloid protein in the media and adventitia of small arteries and capillaries. It may be an independent disease, but is often combined with Alzheimer's disease (AD). This review will discuss up-to-date understanding of the pathophysiology, clinical manifestations of CAA, its diagnosis with neuroimaging and biomarkers.

[Clinical, neuropsychological and neuroimaging features of patients with mixed dementia].

Objective. Mixed dementia (MD), characterized by a combination of Alzheimer's disease (AD) and cerebrovascular disease, is one of the most common and, at the same time, poorly diagnosed forms of dementia in the elderly. The aim of our study was to investigate features of AD with its combination with cerebrovascular disease on the basis of clinical, neuropsychological and neuroimaging data.

[Cerebral microbleeds in cerebrovascular and neurodegenerative diseases].

Cerebral microbleeds (CMBs) are a kind of the morphological changes of the brain associated with damage to small cerebral arteries detected on GRE MRI as small, round, well-defined, hypointense lesions, sized 3-10 mm, which indicate the deposition of hemosiderin. CMBs can be detected in cerebral microangiopathy of different origins (cerebral amyloid angiopathy, hypertensive arteriopathy, vasculitis, hereditary angiopathy) and may be a predictor of macrobleeds. This article discusses the clinical significance of CMBs in cerebrovascular, neurodegenerative diseases, cognitive disorders as well as the possibility of using antiplatelet agents and anticoagulants in patients with CMBs.
