According to the National Institute of Neurological Disorders and Stroke, Wallenberg Syndrome (aka Lateral Medullary Syndrome or Posterior Inferior Cerebellar Artery Syndrome) is a neurological condition caused by a blockage of the vertebral artery (VA) or posterior inferior cerebellar artery (PICA), ultimately leading to infarction of the lateral medulla [1]. Bow hunter's syndrome (BHS) is most commonly caused by compression of the vertebral artery (VA). A solid understanding of the pathophysiology of a posterior cerebral artery (PCA) stroke as well as the syndrome relating to it, requires adequate knowledge of the structures and vascular anatomy of the brain. 1 author.
