CLINICAL FEATURES OF ACUTE AND CHRONIC VERTEBROBASILAR INSUFFICIENCY

Аннотация

The article presents an overview of current data on the clinical features of acute and chronic vertebrobasilar insufficiency (VBI). Pathogenetic mechanisms, main neurological syndromes, diagnostic approaches and current treatment methods are considered. Comparative characteristics of clinical manifestations of acute and chronic forms, as well as conditional clinical examples are given. Vertebrobasilar insufficiency (VBI) is insufficient blood flow through the posterior cerebral circulation, which is supplied by two vertebral arteries that merge to form the basilar artery. The vertebrobasilar vascular system is also known as the posterior circulation and supplies areas such as the brainstem, thalamus, hippocampus, cerebellum, occipital and medial temporal lobes. Stroke may result from either vertebral or basilar artery occlusion or from an embolus that lodges more proximally to the brain. In emergency settings, VBI is an important differential diagnosis to consider. Its presentation may share features with other etiologies including labyrinthitis, vestibular neuritis, and benign paroxysmal positional vertigo (BPPV). This event reviews the evaluation and management of vertebrobasilar insufficiency and highlights the role of multidisciplinary team members in collaboration to provide well-coordinated care and improve outcomes for patients with this condition.
