Vertebrobasilar insufficiency (VBI) refers to a temporary set of symptoms due to decreased blood flow (ischemia) in the posterior circulation of the brain. The posterior circulation supplies blood to the medulla, cerebellum, pons, midbrain, thalamus, and occipital cortex (which controls vision).
Causes[edit]
Vertebrobasilar insufficiency is typically caused by atherosclerosis, a disease in which plaque builds up inside your arteries. Other causes can include dissection of the vertebral or basilar artery and fibromuscular dysplasia.
Symptoms[edit]
Symptoms of vertebrobasilar insufficiency are due to ischemia of the areas that the vertebrobasilar system supplies. These can include dizziness, vertigo, diplopia, perioral numbness, hearing loss, tinnitus, ataxia, dysarthria, dysphagia, weakness, syncope, sensory loss, nystagmus, and nausea and vomiting.
Diagnosis[edit]
Diagnosis of vertebrobasilar insufficiency is typically made based on the patient's symptoms and medical history. Imaging tests such as MRI or CT scan may be used to confirm the diagnosis.
Treatment[edit]
Treatment for vertebrobasilar insufficiency typically involves managing the underlying cause, such as atherosclerosis. This can include lifestyle changes, medication, or in some cases, surgery.
