Vertebrobasilar Strokes are interruptions of blood flow to the posterior circulation. While these types of strokes are relatively uncommon, they are a disproportionate cause of morbidity and mortality when compared to anterior circulation strokes due to discreet symptoms that also Read More …

Vertebrobasilar (VB) Systems – Anatomy, Functions
The vertebrobasilar (VB) system, comprised of the vertebral and basilar arteries, serves as a critical arterial supply to the cervical spinal cord brainstem, cerebellum, thalamus, and occipital lobes. Disruptions of VB circulation can have devastating neurologic consequences; thus, a thorough Read More …
Vertebrobasilar Insufficiency – Causes, Symptoms, Treatment
Vertebrobasilar insufficiency (VBI) is defined by inadequate blood flow through the posterior circulation of the brain, supplied by the 2 vertebral arteries that merge to form the basilar artery. The vertebrobasilar arteries supply the cerebellum, medulla, midbrain, and occipital cortex. Read More …
Mini Stroke (Transient Ischemic Stroke) – Symptom, Treatment
Mini Stroke (Transient Ischemic Stroke)/A Transient Ischemic Stroke (TIA) is a medical emergency. It is defined as a transient episode of neurologic dysfunction due to the focal brain, spinal cord, or retinal ischemia, without acute infarction or tissue injury. The Read More …

Ischemic Stroke Syndromes – Causes, Symptoms, Treatment
Ischemic stroke syndromes have a multitude of possible causes, characterized by a rule of quarters: 25% cardioembolic, 25% artery embolic (large-artery disease), 25% lacunar (small-vessel disease), and 25% due to other causes, with global variation in proportions by population.[rx] In Read More …
