Vertigo is a relatively common symptom that can result from ischemia to the cerebellum, medulla or (rarely) the internal auditory artery which supplies the vestibular system of the inner ear. While vertigo is a common feature of VBI or posterior circulation stroke, VBI only rarely presents with vertigo alone (without other neurological signs). [5]
The proximal part of left subclavian is blocked (shaded artery). This prevents antegrade ("forward") flow to the left arm and left vertebral. As a result, flow in the left vertebral is retrograde ("backwards") towards the left arm. Flow to the brain and circle of Willis is via antegrade right and left carotid and right vertebral arteries.

Spinal stenosis is an abnormal narrowing of the spinal canal or neural foramen that results in pressure on the spinal cord or nerve roots. [6] Symptoms may include pain, numbness, or weakness in the arms or legs. [1] Symptoms are typically gradual in onset and improve with leaning forward. [1]
Lateral medullary syndrome is a neurological disorder causing a range of symptoms due to ischemia in the lateral part of the medulla oblongata in the brainstem.The ischemia is a result of a blockage most commonly in the vertebral artery or the posterior inferior cerebellar artery. [1]
Vertigo or dizziness; Weakness of limbs; Symptoms are frequently worsened by a Valsalva maneuver, or by being upright for long periods of time. The reason that being upright is problematic is that gravity allows increased interaction between the brain stem and the top of the spinal column, increasing symptoms.
The treatment options vary since there are numerous causes of cervicocranial syndrome. General treatments include: Pressure release via realignment of the vertebrae; Pain medication: acetominophen, aspirin, or ibuprofen; Manipulation of neck by chiropractor: For example, vertigo symptoms can be relieved [25]
Cardinal signs include vertigo, headache, vomiting, and ataxia. [2] Left sided cerebellar stroke due to occlusion of a vertebral artery. Cerebellar strokes account for only 2-3% of the 600,000 strokes that occur each year in the United States. [3] They are far less common than strokes which occur in the cerebral hemispheres.
Treatment is determined based on the primary cause of anterior spinal cord syndrome. When the diagnosis of anterior spinal cord syndrome is determined, the prognosis is unfortunate. The mortality rate is approximately 20%, with 50% of individuals living with anterior spinal cord syndrome having very little or no changes in symptoms. [1]
