Learn about the causes, symptoms, and treatment of PCA stroke, a rare but potentially devastating type of cerebrovascular accident. Find out how the PCA supplies the midbrain, thalamus, and occipital lobe, and what are the common complications and variants of PCA anatomy.
19 Μαΐ 2014 · This article reviews the epidemiology, pathophysiology, clinical features, and management of posterior circulation stroke, which affects 20-25% of ischaemic strokes. It also discusses the challenges of recognising and treating posterior circulation stroke, such as delayed diagnosis, inadequate imaging, and high recurrence risk.
Keywords: posterior circulation, stroke, basilar artery, vertebral artery, stroke management. Defining the Posterior Circulation. A posterior circulation (PC) stroke is classically defined by infarction occurring within the vascular territory supplied by the vertebrobasilar (VB) arterial system.
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. Anterior and posterior circulations provide the primary blood circulation of the brain.
14 Σεπ 2023 · Posterior circulation cerebral infarction (PCCI) includes ischemia to brain territories supplied by the posterior cerebral arteries, basilar artery, intracranial, and extracranial vertebral arteries. PCCI accounts for approximately 26 % of all ischemic strokes.
24 Μαΐ 2023 · Cerebral infarction of the posterior cerebral artery (PCA) territory accounts for 6% to 9% of patients with ischemic stroke. 1,2 Ischemic stroke in the distribution of the PCA can result in loss of vision, cognitive changes, hemisensory loss, hemiparesis, and occasionally alteration or loss of consciousness with infarction of the artery of ...
