Age-Specific Associations of Renal Impairment With Magnetic Resonance Imaging Markers of Cerebral Small Vessel Disease in Transient Ischemic Attack and Stroke Clinical Sciences
Background and Purpose—It has been hypothesized that cerebral small vessel disease (SVD) and chronic renal impairment may be part of a multisystem small-vessel disorder, but their association may simply be as a result of shared risk factors (eg, hypertension) rather than to a systemic susceptibility to premature SVD. However, most previous studies were hospital based, most had inadequate adjustment for hypertension, many were confined to patients with lacunar stroke, and none stratified by age.Methods—In a population-based study of transient ischemic attack and ischemic stroke (OXVASC [Oxford Vascular Study]), we evalu...

Outcomes after Tissue Plasminogen Activator Administration under the Drip and Ship Paradigm May Differ According to the Regional Stroke Care System
The drip and ship paradigm for stroke patients enhances the rate of using intravenous tissue plasminogen activator (IVT) in community hospitals. The safety and outcomes of patients treated with IVT for acute ischemic stroke (AIS) under the drip and ship paradigm were compared with patients directly treated at a comprehensive stroke center in the Busan metropolitan area of Korea. This was a retrospective study of patients with AIS treated with IVT between January 2009 and January 2012. Information on patients' baseline characteristics, neuroimaging, symptomatic intracerebral hemorrhage (sICH), and outcome 90 days after usi...

Early Magnetic Resonance Imaging Decreases Hospital Length of Stay in Patients with Ischemic Stroke
Imaging modalities are important part of stroke evaluation. Noncontrast head computed tomography (CT) is the initial imaging modality in acute stroke and although important to rule out acute hemorrhage and making a decision on thrombolytic treatment, ischemic changes may not be visible on CT for up to 24 hours. Magnetic resonance imaging (MRI) brain is an invaluable tool to confirm an ischemic stroke and facilitates stroke evaluation. Objective of this study was to investigate the correlation between time to MRI and length of hospital stay.

A Case of Recurrent Ischemic Stroke Involving Subacute, Progressive Intracranial Cerebral Arterial Sclerosis Prior to Diagnosis with -mutated Polycythemia Vera
A 58-year-old man presenting with no vascular risk factors visited our hospital with right hemiparesis and total aphasia. Diffusion-weighted magnetic resonance imaging of the brain showed multiple hyperintensities in watershed distributions in the left hemisphere. Magnetic resonance angiography (MRA) revealed stenosis of the middle cerebral artery, despite normal MRA findings 2 months prior. One year after the first stroke, the patient experienced a recurrent ischemic stroke involving the left anterior choroidal artery, pulmonary embolism, and deep venous thrombosis.

Implementation of a Community-Based Triage for Patients with Suspected Transient Ischemic Attack or Minor Stroke Study: A Prospective Multicenter Observational Study
Japan has the highest number of magnetic resonance imaging units in the world, and citizens can freely choose medical care at any hospital or clinic. We aimed to investigate the triage of patients with suspected transient ischemic attack (TIA) or minor stroke in this unique Japanese healthcare system.

Short-Term Risk of Ischemic Stroke After Detection of Left Ventricular Thrombus on Cardiac Magnetic Resonance Imaging
Background: The short-term risk of ischemic stroke in patients with left ventricular (LV) thrombus identified via delayed-enhancement cardiac magnetic resonance (DE-CMR) imaging is uncertain. Methods: We performed a retrospective cohort study of patients who underwent DE-CMR for evaluation of LV systolic dysfunction at NewYork-Presbyterian Hospital/Weill Cornell between 2007 and 2016. We identified all hospitalized patients who had DE-CMR evidence of LV thrombus, and as controls, all hospitalized patients who had no DE-CMR evidence of LV thrombus; 2 control patients were randomly selected for each patient with LV thrombus.

Laryngeal Elevation Velocity and Aspiration in Acute Ischemic Stroke Patients
This study aimed to explore the ability of laryngeal elevation velocity to predict aspiration in patients with acute ischemic stroke. MethodsThis was a prospective cohort study that included consecutive acute ischemic stroke patients treated at a teaching hospital during a 10-month period. Patients underwent magnetic resonance imaging (MRI) to confirm the diagnosis of acute ischemic stroke. Patients who were at risk of aspiration and could swallow 5 ml of diluted barium (40%, w/v) for a videofluoroscopic swallowing (VFS) study were included. The association between abnormal indices in the oral and pharyngeal phase of the V...

Stroke mimics: incidence, aetiology, clinical features and treatment
Ann Med. 2021 Dec;53(1):420-436. doi: 10.1080/07853890.2021.1890205.ABSTRACTMimics account for almost half of hospital admissions for suspected stroke. Stroke mimics may present as a functional (conversion) disorder or may be part of the symptomatology of a neurological or medical disorder. While many underlying conditions can be recognized rapidly by careful assessment, a significant proportion of patients unfortunately still receive thrombolysis and admission to a high-intensity stroke unit with inherent risks and unnecessary costs. Accurate diagnosis is important as recurrent presentations may be common in many disorder...

Association between radiographic Wallerian degeneration and neuropathological changes post childhood stroke
Aim Wallerian degeneration is a radiological finding thought to reflect corticospinal tract degeneration. This finding on magnetic resonance imaging (MRI) is routinely used as a predictor of poor prognosis in childhood stroke. However, its validity has never been established. Our objective was to correlate Wallerian degeneration seen on MRI with histopathology.
Method We searched the databases of the Department of Pathology and Children’s Stroke registry at the Hospital for Sick Children, Toronto for autopsy specimens exhibiting focal infarcts from children born at term who underwent MRI after a stroke. The specime...

Combining transcranial ultrasound with intelligent communication methods to enhance the remote assessment and management of stroke patients: Framework for a technology demonstrator
With over 150,000 strokes in the United Kingdom every year, and more than 1 million living survivors, stroke is the third most common cause of death and the leading cause of severe physical disability among adults. A major challenge in administering timely treatment is determining whether the stroke is due to vascular blockage (ischaemic) or haemorrhage. For patients with ischaemic stroke, thrombolysis (i.e. pharmacological ‘clot-busting’) can improve outcomes when delivered swiftly after onset, and current National Health Service Quality Improvement Scotland guidelines are for thrombolytic therapy to be provid...
