Vertebrobasilar Circulation Transient Ischemic Attack, also known as Vertebral-Basilar Transient Ischemic Attack (TIA), is a medical condition characterized by a temporary disruption of blood flow to the posterior circulation of the brain.
The vertebrobasilar circulation refers to the blood supply that nourishes the brainstem and the back part of the brain, including the cerebellum. A transient ischemic attack (TIA) is a temporary episode of blood flow interruption to a particular area of the brain, resulting from a blocked or narrowed blood vessel. In the case of a vertebrobasilar TIA, the affected blood vessel is typically one of the vertebral or basilar arteries.
This condition often presents with symptoms similar to a stroke, such as sudden confusion, dizziness, slurred speech, loss of coordination, and numbness or weakness in the face, arm, or leg. However, the symptoms of a TIA usually resolve within a short period, typically less than 24 hours.
Vertebrobasilar circulation TIAs are frequently caused by the presence of a blood clot traveling from another part of the body, such as the heart or carotid arteries, and becoming lodged in one of the arteries leading to the brain. Other potential causes include atherosclerosis (narrowing of the blood vessels), arteritis (inflammation of the arteries), or a dissection (tear) in the artery walls.
Prompt medical attention is crucial when a vertebrobasilar TIA is suspected, as it may be a warning sign of an impending stroke. Diagnostic tests, such as magnetic resonance imaging (MRI) or computed tomography (CT) scans, may be employed to identify the underlying cause and determine
