What type of TIA results from inadequate blood flow from the vertebral arteries?

The type of transient ischemic attack (TIA) that results from inadequate blood flow from the vertebral arteries is vertebrobasilar TIA. This condition occurs when there is a temporary reduction in blood flow through the vertebral and basilar arteries, which can lead to a variety of neurological symptoms due to ischemia in the posterior circulation of the brain. The posterior circulation is responsible for perfusing brain structures that are crucial for balancing, coordination, and visual processing, among other functions.

Symptoms of a vertebrobasilar TIA may include dizziness, vertigo, bilateral vision changes, weakness, and ataxia. Identifying a vertebrobasilar TIA is important for timely management, as these patients are at risk for stroke and require appropriate evaluation and intervention to improve their outcomes.

The other choices do not specifically relate to deficiencies in blood flow from the vertebral arteries. For instance, cardioembolic TIAs are associated with emboli originating from the heart, while the subclavian steal syndrome involves a hemodynamic change due to stenosis or occlusion in the subclavian artery, leading to reversal of flow in the vertebral artery, but not directly from inadequate blood flow in the vertebral arteries themselves.
