![]() Both circulations are connected by the posterior. Anterior and posterior circulations provide the primary blood circulation of the brain. Cerebellar Disorders: A Practical Approach to Diagnosis and Management. A solid understanding of the pathophysiology of a posterior cerebral artery (PCA) stroke as well as the syndrome relating to it, requires adequate knowledge of the structures and vascular anatomy of the brain. In Schwab, Stefan Hanley, Daniel Mendelow, A. Oxford Textbook of Stroke and Cerebrovascular Disease. "Diagnosis and initial management of cerebellar infarction". "Cerebellar infarction: Natural history, prognosis, and pathology". "Functional recovery after rehabilitation for cerebellar stroke". Doctors also refer to Wallenberg syndrome as lateral medullary syndrome, posterior inferior cerebellar artery (PICA) syndrome, or vertebral artery syndrome. PICA POSTERIOR INFERIOR CEREBELLAR ARTERY The PICA is a truly fascinating vessel. (Posterior inferior cerebellar artery is PICA.) ICD-10, G46.3. "Dysarthria in acute ischemic stroke: Lesion topography, clinicoradiologic correlation, and etiology". The three major arteries of the cerebellum: the SCA, AICA, and PICA. Stroke to the midline of the cerebellum (a.k.a.Research is still needed in the area of cerebellar stroke management however, several factors may lead to poor outcomes in individuals who have a cerebellar stroke. Advancements have also been made which allow earlier management for common complications of cerebellar stroke such as brainstem compression and hydrocephalus. Twenty percent of ischemic events in the brain involve posterior circulation (vertebrobasilar) structures. In recent years mortality rates have decreased due to advancements in health care which include earlier diagnosis through MRI and CT scanning. They are far less common than strokes which occur in the cerebral hemispheres. Left sided cerebellar stroke due to occlusion of a vertebral arteryĬerebellar strokes account for only 2-3% of the 600,000 strokes that occur each year in the United States. Ĭardinal signs include vertigo, headache, vomiting, and ataxia. The three major arteries of the cerebellum: the SCA, AICA, and PICAĬerebellar stroke syndrome is a condition in which the circulation to the cerebellum is impaired due to a lesion of the superior cerebellar artery, anterior inferior cerebellar artery or the posterior inferior cerebellar artery. ![]() Medical condition Cerebellar stroke syndrome ![]()
