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.You can learn more about how we ensure our content is accurate and current by reading our editorial policy.

Recurrent cardiac arrest caused by lateral medulla oblongata infarction. It occurs due to the involvement of lateral segment of medulla either caused by thrombotic or embolic occlusion of vertebral artery or posterior inferior cerebellar artery (PICA. References von Heinemann P, Grauer O, Schuierer G, et al. Lateral medullary syndrome (LMS) was first described by Gaspard Vieussux in 1808 and the first clinical description of this syndrome was given by Wallenberg in 1895. fibromuscular dysplasia, a condition that affects the artery walls Conduction disturbances, caused by autonomic dysregulation, are uncommon during acute ischaemic stroke, but can be seen in lateral medullary syndrome (Wallenberg or PICA syndrome) 1, 2.Ehler-Danlos syndrome, a group of genetic disorders that affect the body’s connective tissues.Marfan syndrome, a genetic condition that affects connective tissues.Other potential risk factors may include:Īdditionally, a vertebral artery dissection, or a flap-like tear of the inner lining of the vertebral artery, can result in a stroke that may lead to Wallenberg syndrome. The involvement of these arteries and parts of the brain is where many of the other names for the condition originate.Įvidence notes that hypertension is the most common risk factor for Wallenberg syndrome. An insufficient blood supply can damage the lateral part of the medulla oblongata, resulting in the symptoms of Wallenberg syndrome. The brainstem is a lower extension of the brain and is responsible for many important functions, such as eye movement, balance, and swallowing. ![]() This area of the brain includes the different parts of the brain stem, most notably the medulla oblongata. This results in insufficient blood reaching the posterior, or back, portion of the brain. Specifically, a blockage occurs in the vertebrobasilar system, most commonly in the posterior inferior cerebellar artery, or the vertebral artery. When oxygenated blood does not reach part of the brain due to a blockage, that part of the brain may become damaged or die. Wallenberg syndrome occurs due to an ischemic stroke occurring in one of the arteries that supply blood to the back portion of the brain.
