![]() ![]() It has correlations with aortic dilations, ectatic coronary arteries, Marfan syndrome, late-onset Pompe disease, and the autosomal dominant polycystic kidney disease. Risk factors for vertebrobasilar dolichoectasia include male gender, hypertension, smoking, and previous myocardial infarction. Vertebrobasilar dolichoectasia: Patients may present with vertebrobasilar territory ischemia.Hypoplastic Vertebral artery: It may rarely contribute to stroke if additional risk factors are present in young patients.Embolism can also occur in cocaine misuse, neck manipulation, medullary neoplasms, radionecrosis, and hematoma. Cardiogenic embolism: Cardiac diseases with risk for embolism include atrial fibrillation, mechanical prosthetic valves, left atrial or ventricular thrombus, dilated cardiomyopathy, myocardial infarction, and infective endocarditis.Dissection of vertebral arteries: In a young patient presenting with migraine and signs and symptoms of the LMS, vertebral artery dissection and aneurysm merit consideration.Atherosclerotic disease: can result in thromboembolism, or rarely, hemodynamic failure leading to ischemia.EtiologyĮtiology of the lateral medullary syndrome include: The damage is to the inferior cerebellar peduncle and dorsolateral medulla, descending spinal tract, the nucleus of the trigeminal nerve, nuclei, and fibers of the vagus nerves and glossopharyngeal, descending sympathetic tract fibers, spinothalamic tract, and vestibular nuclei. Lateral medullary syndrome characteristically has varied neurologic manifestations. The arteries commonly involved in LMS are the posterior inferior cerebellar artery (PICA) or the vertebral artery. It was named after Adolf Wallenberg (1862-1949), who was a renowned Jewish neurologist and neuroanatomist who practiced in Germany. Lateral medullary syndrome (LMS), also called Wallenberg syndrome or posterior inferior cerebellar artery syndrome results from a vascular event in the lateral part of the medulla oblongata. Summarize interprofessional team strategies for improving care coordination and communication to advance the management of the lateral medullary syndrome and improve outcomes.Outline the treatment and management options available for the lateral medullary syndrome.Review the evaluation of the lateral medullary syndrome.Identify the etiology of the lateral medullary syndrome.This activity outlines the evaluation and management of lateral medullary syndrome and reviews the role of the healthcare team in managing patients with lateral medullary syndrome. ![]() The arteries commonly involved in lateral medullary syndrome are the posterior inferior cerebellar artery or the vertebral artery.
