Posterior circulation ischaemic stroke.
There are important differences between posterior and anterior circulation stroke. The differences include the value of screening instruments, optimum diagnos‐ tic modalities, and clinical features (table). The face arm speech test (FAST), a widely used prehospital stroke recognition screening instrument, is less sensitive for detecting posterior circulation stroke than for anterior cir‐ culati...
متن کاملDynamic CT perfusion imaging of acute stroke.
BACKGROUND AND PURPOSE Because cerebral perfusion imaging for acute stroke is unavailable in most hospitals, we investigated the feasibility of a method of perfusion scanning that can be performed rapidly during standard cranial CT. Our aim was to identify the scanning parameters best suited to indicate tissue at risk and to measure a perfusion limit to predict infarction. METHODS Seventy pat...
متن کاملKhorasan Posterior Circulation Stroke Regis-try: a Hospital-Based Study
Background: Clinical information about stroke in the vertebrobasilar territory has lagged behind that for anterior circulation syndrome. This is the first report from posterior circulation syndrome registry in Iran. Methods: Consecutive patients with brain infarction in vertebrobasilar territory admitted to Ghaem hospital, Mashhad were enrolled in a prospective study during 2006-2007. Diagnosis...
متن کاملOutcomes of intravenous thrombolysis in posterior versus anterior circulation stroke.
BACKGROUND AND PURPOSE Intravenous thrombolysis is an approved treatment for anterior (ACS) and posterior (PCS) circulation stroke. However, no randomized controlled trial has investigated safety and efficacy of intravenous thrombolysis according to stroke territory, although PCS is assumed to differ from ACS in many ways. We aimed to compare the safety and clinical outcome of intravenous throm...
متن کاملHyperdense basilar artery sign on unenhanced CT predicts thrombus and outcome in acute posterior circulation stroke.
BACKGROUND AND PURPOSE In acute stroke patients, the presence of a hyperdense middle cerebral artery sign on unenhanced CT is a specific but insensitive indicator of acute thrombosis. Our purpose was to determine whether the hyperdense basilar artery (HDBA) sign has utility in detecting thrombosis and predicting outcome in patients presenting with signs and symptoms of posterior circulation str...
