Symptoms of Vertebral Artery Insufficiency

Vertebrobasilar insufficiency (VBI) refers to a constellation of intermittent, recurrent neurological deficits caused by stenosis—or narrowing—of the vertebrobasilar arterial system due to various underlying etiologies. Below, we address the question: What are the symptoms of vertebral artery insufficiency?

Symptoms of Vertebral Artery Insufficiency

Clinically, vertebral artery insufficiency may manifest as diplopia, vertigo, ataxia, dysphagia, and motor or sensory deficits. Treatment options include oral pharmacotherapy and surgical intervention.

Vertebral artery insufficiency is primarily attributable to atherosclerosis and arterial stenosis; however, it may also be associated with cervical spondylosis or vertebral artery dissection. Patients commonly present with diplopia and dysphagia, and may also experience vertigo, ataxia, and—in some cases—motor or sensory disturbances.

Under medical supervision, antiplatelet agents such as enteric-coated aspirin tablets, dipyridamole tablets, or clopidogrel hydrogen sulfate tablets may be prescribed. Medications must be taken strictly as directed by a physician; self-medication should be avoided to prevent adverse reactions. If pharmacological treatment fails to yield improvement, surgical options—including vertebral endarterectomy—may be considered.

In daily life, patients should prioritize adequate rest and sufficient sleep, avoid excessive physical exertion, and refrain from consuming spicy or irritating foods—such as chili peppers and ginger.

The above outlines the key clinical manifestations of vertebral artery insufficiency. We hope this information proves helpful to you.
