It ends at the level of a rostrocaudal line that passes through the most prominent part of the inferior olive. The anterior medullary segment begins at the origin of the PICA.The trunk of PICA is divided into five segments: The fourth segment of the vertebral artery gives off the PICA, the largest branch of the vertebral artery. The vertebral artery, arising from the subclavian artery, is classically divided into four segments. The posterior inferior cerebellar artery (PICA) usually originates from the vertebral artery at an average distance of approximately 16 or 17 mm below the vertebrobasilar junction. This neurological disorder is associated with various symptoms that result from damage to the lateral segment of the medulla posterior to the inferior olivary nucleus. Wallenberg syndrome is also called lateral medullary or posterior inferior cerebellar artery syndrome. However, a more detailed description given in 1895 by Adolf Wallenberg identified this condition as infarction of the lateral medulla oblongata following occlusion of the vertebral artery (VA) or Posterior inferior cerebellar artery (PICA). Wallenberg syndrome was first described in 1808 by Gaspard Vieusseux. Explain a well-coordinated, interprofessional team approach to effectively care for patients affected by Wallenberg syndrome.

Summarize how to evaluate for Wallenberg syndrome.Review the differential diagnosis of Wallenberg syndrome.Describe the pathophysiology of Wallenberg syndrome.This activity explains when this condition should be considered as part of a differential diagnosis, articulates how to evaluate this condition, and highlight the role of an interprofessional team in caring for patients with this condition. It is the most common posterior circulation ischemic stroke syndrome. Wallenberg syndrome is also called lateral medullary and posterior inferior cerebellar artery syndrome.
