The most common mechanism of occlusion of the vertebral artery or PICA is atherothrombosis. Posterior inferior cerebellar artery (lateral medullary syndrome, Wallenberg syndrome). The majority (80%) of cases are caused by occlusion of the vertebral artery, which gives rise to the PICA and the anterior spinal artery before it joins with the opposite vertebral artery to form the basilar artery. Step 1 Diagnosis of a parkinsonian syndrome Bradykinesia (slow to. Anatomically the infarcted area in Wallenberg syndrome is supplied by the posterior inferior cerebellar artery (PICA). It turns out occlusion of the PICA accounts for only a small number of cases. Wallenberg syndrome, also known as lateral medullary syndrome, is one of the most recognized brain-stem strokes.1 It was first described by Adolf Wallenberg in 1895 by clinical observations of the symptoms on a living patient and was later confirmed by pathology via autopsy. The syndrome can also be due to occlusion of the vertebral artery, or the inferior, middle, or superior medullary vessels. The primary pathology of Wallenberg syndrome is occlusion of the posterior inferior cerebellar artery (PICA) or one of its branches (2). Large artery atherothrombotic causes account for about 75% of the cases followed by cardioembolism in 17% and vertebral dissection in 8%(1). All of the following features are seen in lateral medullary or Wallenbergs syndrome except. There was a predominance of middle aged men. inferior cerebellar artery (PICA) stroke or Wallenbergs syndrome.
Twenty percent of the ischemic strokes occur in the posterior circulation. If clinicians assume that about half of these suffer from Wallenberg syndrome. Clinical symptoms: 1 point for speech impairment without weakness and 2 points for. ARTERY (PICA) SYNDROME is characterized by dissociated sensory loss (see.
