Etiology: Most commonly caused by atherothrombotic occlusion of the vertebral artery (then posterior Lateral medullary syndrome is a neurological disorder causing a range of symptoms due to ischemia in the lateral part of the medulla oblongata in the brainstem.The ischemia is a result of a blockage most commonly in the vertebral artery or the posterior inferior cerebellar artery. Lateral medullary syndrome (also known as Wallenberg syndrome, posterior inferior cerebellar artery (PICA) syndrome, and vertebral artery syndrome) is a neurological constellation of symptoms and signs due to obstruction in vessels supplying the medulla, resulting in brainstem ischemia or infarction. Lateral medullary syndrome is a neurological disorder causing a range of symptoms due to ischemia in the lateral part of the medulla oblongata in the brainstem.The ischemia is a result of a blockage most commonly in the vertebral artery or the posterior inferior cerebellar artery. I'll start with the events that landed me in the intensive care unit. Mnemonic! It's often caused by a stroke in the brain stem - the. Hypertension is the most common risk factor. Horner's syndrome, a common finding in Wallenberg syndrome. Specifically, the right vertebral artery became completely occluded. Wallenberg's syndrome is a neurological condition caused by a stroke in the vertebral or posterior inferior cerebellar artery of the brain stem. Disease Wallenberg syndrome (WS) is a neurological disorder that is due to damage to the lateral portion of the medulla oblongata (i.e., the lateral medullary syndrome). Contents 1 Signs and symptoms 1.1 Based on location 2 Cause 3 Diagnosis The primary pathology of Wallenberg syndrome is occlusion of the posterior inferior cerebellar artery (PICA) or one of its branches. The syndrome is caused by a variety of diseases that lead to occlusion of the vertebral artery or the posterior inferior cerebellar artery (PICA). Lateral medullary syndrome is also called Wallenberg's syndrome, posterior inferior cerebellar artery (PICA. Wallenberg syndrome (WS) is a clinical brainstem syndrome that is typically due to an ischemic infarction of the lateral medulla, often associated with a vascular lesion of the posterior inferior cerebellar arteries (PICA) and/or vertebral arteries. The ischemia is a result of a blockage most commonly in the vertebral artery or the posterior inferior cerebellar artery. Patients experience difficulty swallowing and/or speaking.
