The diagnosis of posterior circulation stroke or TIA can be made on the basis of history and physical examination, which should include exclusion of alternative causes for the patient's symptoms and consideration of risk factors for atherosclerosis. To confirm VBI, imaging studies of the posterior circulation can be performed.
TOS has been reported to cause stroke through theorized clot propagation towards the vertebral artery; [3] a similar mechanism could explain how TOS causes SSS. Presence of a cervical rib is a risk factor for both TOS and SSS. [citation needed] Takayasu's arteritis is a disease causing inflammation of arteries, including the subclavian artery ...

Brain ischemia has been linked to a variety of diseases or abnormalities. Individuals with sickle cell anemia, compressed blood vessels, ventricular tachycardia, plaque buildup in the arteries, blood clots, extremely low blood pressure as a result of heart attack, and congenital heart defects have a higher predisposition to brain ischemia in comparison to the average population.
The most common presentation of cerebrovascular disease is an ischemic stroke or mini-stroke and sometimes a hemorrhagic stroke. [2] Hypertension (high blood pressure) is the most important contributing risk factor for stroke and cerebrovascular diseases as it can change the structure of blood vessels and result in atherosclerosis.

Posterior circulation infarct (POCI) is a type of cerebral infarction affecting the posterior circulation supplying one side of the brain.. Posterior circulation stroke syndrome (POCS) refers to the symptoms of a patient who clinically appears to have had a posterior circulation infarct, but who has not yet had any diagnostic imaging (e.g. CT Scan) to confirm the diagnosis.
Impaired blood flow to the cells of the occipital lobe (ischemia, for example as caused by a TIA or Vertebrobasilar insufficiency) will lead to temporary visual problems; if the poor blood flow is sustained it will lead to cell death (infarction, for example as caused by a stroke) which may cause persistent visual problems.
