A 63-year-old man was admitted to our stroke center with brain infarction in the left posterior inferior cerebellar artery (PICA) territory. The initial MRI showed no findings suggestive of arterial dissection, and post-discharge MRI showed no temporal changes. Digital subtraction angiography (DSA) revealed vasodilation of the proximal portion of the PICA but it was uncertain whether dissection was present. Discrepancy between the outer contour seen on constructive interference in steady state (CISS) MRI and the inner contour seen on DSA suggested the presence of intramural hematoma...

OBJECTIVES: We aimed to investigate the risk of recurrent stroke in patients with transcatheter closure of an atrial shunt (ASCIos), compared to patients with an atrial shunt and cerebrovascular event (CVE) but only medical treated (ASMed), and to age- and sex-matched control individuals without a previous CVE. METHODS: In total, 663 ASCIos patients were identified in the Swedish National Patient Register from 1997 to 2016 and matched by using propensity score with 663 ASMed patients...

OBJECTIVES: Stroke survivors often have unmet physical, psychological and/or social concerns. Patient Concerns Inventories (PCIs) have been developed for other health conditions to address concerns. Our objective was to develop a PCI for stroke care. METHODS: This was a development study, including Modified Delphi study design, with academic and healthcare professionals with stroke care expertise. In Stage 1, a draft Stroke PCI (Version 1a) was created through identifying patient-reported concerns post-stroke from three previous studies and through expert panel discussions using Nominal Group Technique...

OBJECTIVE: Although computed tomography perfusion (CTP) is used to select and guide decision-making processes in patients with acute ischemic stroke, there is no clear standardization of the optimal threshold to predict ischemic core volume accurately. The infarct core volume with a relative cerebral blood flow(rCBF) threshold of < 30% is commonly used. We aimed to assess the volumetric agreement of the infarct core volume with different CTP parameters and thresholds using CTP software (RAPID, VITREA) and the infarct volume on diffusion-weighted imaging (DWI), with a short interval time (within 60 min) between CTP and follow-up DWI...

OBJECTIVE: Elongated styloid process (ESP) and carotid web are rare etiologies of ischemic stroke. We report a rare case of ESP concomitant with carotid web as the cause of recurrent stroke. CASE PRESENTATION: A 59-year-old man was admitted to our hospital with recurrent numbness and weakness in the right upper extremity. The patient had a long-standing history of lightheadedness and left-side amaurosis with neck flexion. Magnetic resonance imaging (MRI) confirmed scattered infarctions in the left frontal and parietal lobes...

OBJECTIVES: Stroke epidemiology varies among different populations. The burden of stroke is high in low- and middle-income countries. Reliable population data is needed to assess the impact of stroke and to develop policies aimed to improve stroke care in our region. EstEPA is a population-based project assessing prevalence, incidence, mortality and burden of stroke in General Villegas Department, Buenos Aires, Argentina (pop=30,864 inhabitants). We determined incidence of stroke (first-ever and recurrent stroke) and stroke case-fatality rate from 2017 to 2020...

BACKGROUND: Mechanical Thrombectomy (MT) is standard of care for eligible patients with Acute Ischemic Stroke (AIS) due to large vessel occlusion (LVO). With increasing use of MT, clinicians are more likely to encounter seizures, a potential complication of AIS treated with MT. Tracking future trends in the burden of post-stroke seizure associated with MT will require baseline pre-approval benchmark estimates of its frequency and outcomes. METHODS: All patients with AIS who underwent MT (International Classification of Diseases, Ninth Revision, Clinical Modification; ICD-9-CM procedure code: 39...

A 40-year-old man with sensorineural hearing loss and diabetes mellitus was hospitalized with acute-onset impaired consciousness and clumsiness in his left hand. He had been taking metformin for 4 months. A neurological examination revealed confusion and weakness in the left upper limb. Increased lactate levels were detected in the serum and cerebrospinal fluid. Magnetic resonance imaging revealed lesions in the right parietal and bilateral temporal lobes with a lactate peak in magnetic resonance spectroscopy...

BACKGROUND: Transcranial Doppler flow velocity is used to monitor for cerebral vasospasm following aneurysmal subarachnoid hemorrhage. Generally, blood flow velocities appear inversely related to the square of vessel diameter representing local fluid dynamics. However, studies of flow velocity-diameter relationships are few, and may identify vessels for which diameter changes are better correlated with Doppler velocity. We therefore studied a large retrospective cohort with concurrent transcranial Doppler velocities and angiographic vessel diameters...

BACKGROUND: Numerous ischaemic stroke patients experience poor functional outcome despite successful recanalisation following endovascular thrombectomy (EVT). We aimed to identify the incidence and predictors of futile complete recanalisation (FCR) in a national stroke registry. METHODS: Patients who achieved complete recanalisation (mTICI 3) following EVT, between October 2015 and March 2020, were included from a United Kingdom national stroke registry. Modified Rankin Scale of 4-6 at discharge was defined as a 'poor/futile outcome'...

OBJECTIVES: To characterise mortality and functional outcome and their relationships with socioeconomic deprivation for women and men in Zanzibar. MATERIALS AND METHODS: Participants in ZanStroke, a prospective observational study of patients admitted to hospital with a diagnosis of acute stroke, were followed up until one year after the stroke. The modified National Institute of Health Stroke Scale was used to assess initial stroke severity, while modified Rankin Scale (mRS) was used to assess disability at 12 months post-stroke...

PURPOSE: To compare quality of life (QOL) of individuals with stroke three months after hospital discharge, using generic and specific QOL measures, before and during the COVID-19 pandemic. METHODS: Individuals, who were admitted to a public hospital, were recruited and evaluated before (G1) and during (G2) the COVID-19 pandemic. The groups were matched for age, sex, socio-economic status, and levels of stroke severity (National Institutes of Health Stroke Scale) and functional dependence (Modified Barthel Index)...

OBJECTIVES: In-hospital stroke mortality is surprisingly much worse than for strokes occurring outside of the hospital. Cardiac surgery patients are amongst the highest risk groups for in-hospital stroke and experience high stroke-related mortality. Variability in institutional practices appears to play an important role in the diagnosis, management, and outcome of postoperative stroke. We therefore tested the hypothesis that variability in postoperative stroke management of cardiac surgical patients exists across institutions...

BACKGROUND AND PURPOSE: Studies have shown that mild stroke patients with National Institutes of Health Stroke Scale (NIHSS) score 3-5 but not 0-2 may benefit from the intravenous thrombolysis when compared with antiplatelet therapy. We aimed to compare the safety and effectiveness of thrombolysis in mild stroke with NIHSS score of 0-2 vs. 3-5 and identify the predictors of an excellent functional outcome in a real world longitudinal registry. METHODS: In a prospective thrombolysis registry, we identified patients with acute ischemic stroke who presented within 4...

BACKGROUND: Risk factors for stroke after transcatheter aortic valve implantation (TAVI) are currently incompletely understood. PURPOSE: To identify possible predictors of early post-TAVI stroke and explore its short-term outcomes. METHODS: Retrospective analysis of consecutive patients (pts) submitted to TAVI between 2009 and 2020 in a tertiary center. Baseline characteristics, procedural information and stroke in first 30 days after TAVI were collected...

INTRODUCTION: Dolichoectatic vessels can cause cranial nerve dysfunction by either direct compression or ischemia. Abducens nerve palsy due to neurovascular compression by elongated, enlarged, tortuous or dilated arteries is an uncommon but important cause. AIM: To highlight neurovascular compression as a cause of abducens nerve palsy and discuss various diagnostic techniques. METHODS: Manuscripts were identified using the National Institutes of Health PubMed literature search system...

BACKGROUND: Neuroinflammation after aneurysmal subarachnoid hemorrhage (aSAH) leads to poor outcome of patients. High mobility group box 1 (HMGB1) contributes to inflammation through binding to receptors for advanced glycation end-products (RAGE) in various diseases. We aimed to determine the production of these two factors after aSAH and their relationship with clinical features. METHODS: HMGB1 and soluble RAGE (sRAGE) levels in cerebrospinal fluid (CSF) of aSAH patients and controls were measured, and their temporal courses were observed...
