[Ischaemic lesions of cerebral after carotid stenting].

Carotid angioplasty with stenting is a reliable method of primary and secondary prevention of ischaemic stroke in patients with stenosing lesions of the internal carotid artery. However, carrying out such operations is sometimes associated with risk for the development of intraoperative impairments of cerebral circulation due to arterioarterial embolism in cerebral arteries, as well as vasospasm. Presented herein are the results of following up a total of 64 patients with pronounced atherosclerotic lesions of internal carotid arteries (>70%) - "symptomatic" and "asymptomatic", undergoing carotid stenting.

[Electrophysiological markers of middle cerebral artery blood flow velocity in healthy subjects].

Aim: to determine electrophysiological markers of middle cerebral artery blood flow velocity (BFV).

Patients And Methods: transcranial Doppler registration of middle cerebral artery BFV and direct current (DC) potentials recording from surface of head were performed in 30 healthy volunteers. Analysis of correlation between the BFV and DC potentials was used.

[Lower limb vein thrombosis in dynamics of acute impairments of cerebral circulation].

The present work was aimed at studying the state of the inferior vena cava system according to the findings of duplex scanning in dynamics of acute cerebral circulation impairments (ACCI). Amongst 100 patients with ACCI, lower limb vein deep thrombosis (LLVDT) was revealed in 57% of cases. The incidence of LLVDT in patients with intracerebral haemorrhage was higher than in those with ischaemic stroke, however there were no statistically significant differences between the type of ACCI (p=0.

[Intraoperative monitoring of cerebral blood-flow and condition of cerebral at open and endovascular interventions in carotid system].

The aim of our research is to study hemodynamic and embolic situation during the carotid endarterectomy (CEA), carotid angioplastic and stenting (CAS), and to reveal the prognostic significance of the data provided by intraoperative monitoring of the brain blood flow in exposing acute ischemic lesions in brain. Intraoperative monitoring of blood flow in artery ophthalmic vas carried out with 60% of patients, in the middle cerebral artery-with 40% during the main stages of CEA, and with 64 patients in the middle cerebral artery during CAS. The comparison of the data of intraoperative monitoring of blood flow in middle cerebral artery with the result of brain diffusion-weighted magnetic resonance imaging (DW-MRI) 24 hours after the operation shows, that solid microembolic signals and vasospasm are prognostic signals (sensibility and specifics make up 95%) in the development of acute ischemic cerebral lesions.

[Results of proximal vertebral arteries endovascular interventions].

To evaluate immediate and long-term clinical and ultrasound efficacy of proximal vertebral arteries stenting. We studied 74 subjects (age 61+/-10 years) who underwent transluminal balloon angioplasty with stenting of vertebral arteries (77 vessels). Technical success (i.
