Cerebral infarctions in vertebrobasilar artery atherosclerosis

Vertebrobasilar stroke (VBS) is 20-25% of the ischemic stroke structure, however, the clinical features and long-term outcome of the disease studied poorly in the domestic population.The aim of the study was to analyze the clinical features of the acute period of VBS and calculate the 5-year risk of cardiovascular events and death.Material and methods. We analyzed the data of 1569 patients with ischemic stroke. There were analyses of patient complaints, neurological status, brain imaging, NIHSS and POST-NIHSS. The logistic regression model was built for an integral assessment of predictors of five-year mortality.Results. 386 (25%) patients with VBS were diagnosed and 147 (9,4%) cases of VBS were diagnosed with CT-scan. The top complaints were dizziness, unsteadiness and blurred speech. 72 (48,9%) patients were low neurological deficit, the most common neurological syndromes were ataxia, prosoparesis, hemiparesis, dysarthria and nystagmus. More than 60% of patients had an unspecified stroke subtype, despite the diagnostic search performed. The 19,4% patients were recurrent ischemic stroke and 37,2% patients died. Predictors of mortality were age and the presence of cardiovascular disease. Conclusion. Patients with VBS are characterized by a predominantly nonspecific clinical picture of the disease, in half of the cases a minor neurological deficit, insufficient information content of the initial computed tomography of the brain, a low frequency of intravenous thrombolysis, difficulties in determining the cause of stroke and a high risk of recurrent stroke and death within 5 years.

Cerebral infarctions in vertebrobasilar artery atherosclerosis

Abstract: This investigation could establish the relationship between the site, extent, and pathogenetic factors of infarctions in the VBA bed in atherosclerosis, as well as the prognostic value of small infarctions as predictors for severe ischemic stroke.
