Treatment Outcome of Carotid Artery Stenting Underwent within 14 Days of Stroke Onset - Consideration of Safety and Efficacy of Urgent Carotid Artery Stenting for Neurologically Progressing Patients.
Authors: Kanematsu Y, Satomi J, Kuwayama K, Yamaguchi I, Yoshioka S, Kinouchi T, Tada Y, Yamamoto N, Matsubara S, Satoh K, Nagahiro S Abstract As the safety and effectiveness of urgent carotid artery stenting (CAS) for neurologically progressing patients remain controversial, we retrospectively analyzed the outcome of urgent CAS based on the patients' pathophysiological condition and neuroimaging findings. We divided 71 patients who underwent CAS within 14 days of stroke onset into two groups. Group 1 (n = 35) was comprised of patients with progressing neurologic signs and a reversible ischemic penumbra on magnetic...

Modified diffusion-weighted imaging-Alberta Stroke Program Early Computed Tomography Score including deep white matter lesions predicts symptomatic intracerebral hemorrhage following intravenous thrombolysis
AbstractThe Alberta Stroke Program Early Computed Tomography Score (ASPECTS) is widely used for the assessment of early ischemic changes (EICs) before thrombolysis. However, for symptomatic intracerebral hemorrhage (sICH) following intravenous recombinant tissue plasminogen activator (rt-PA), the prediction abilities of CT-ASPECTS, diffusion-weighted imaging (DWI)-ASPECTS, and DWI-ASPECTS including EICs in deep white matter (DWI-ASPECTS  + W) are unclear. We investigated associations between each score and sICH following intravenous rt-PA. Data from consecutive patients who received intravenous rt-PA for acute ischemic...

Intravenous Thrombolysis at 3.5 Hours From Onset of Pediatric Acute Ischemic Stroke
We report the case of a 14-year-old girl who presented with right-sided weakness and ataxia, loss of sensation, and altered mental status. Magnetic resonance imaging with diffusion-weighted imaging showed an acute lesion in the distribution of the left posterior cerebral artery, and magnetic resonance angiogram demonstrated occlusion of the third branch of the left posterior cerebral artery. With parental consent, clinicians decided to infuse an adult dose of weight-adjusted intravenous alteplase at 3.5 hours from onset of symptoms, with subsequent improvement in National Institutes of Health Stroke Scale score from 11 to ...

A high neutrophil-to-lymphocyte ratio predicts hemorrhagic transformation of large atherosclerotic infarction in patients with acute ischemic stroke.
Abstract Increasing evidence suggests that inflammation is associated with the development of acute ischemic stroke (AIS). The neutrophil-to-lymphocyte ratio (N/L) is an important marker of inflammation and is highly correlated with mortality in stroke patients in recent studies. The N/L of patients who experience hemorrhagic transformation (HT) after AIS is know, but any relationship between N/L and large artery atherosclerosis (LAA) remains unclear, this is our present topic. We enrolled 185 patients with LAA-type HT in the development cohort from a prospective, consecutive, hospital-based stroke registry to thi...

Outcomes of reperfusion therapy for acute ischaemic stroke in patients aged 90 years or older: a retrospective study
AbstractThe benefits and risks of acute reperfusion therapy (RT) in acute ischaemic stroke (AIS) remain uncertain in older patients, especially in nonagenarians. We aimed to assess the impact of RT in this population. Single-center retrospective cohort study comparing patients  ≥ 90 years old admitted to a Stroke Unit (2008–2018) with AIS, submitted or not to RT [intravenous thrombolysis(IVT), mechanical thrombectomy(MT) or both]. Baseline characteristics, in-hospital complications and 3-month outcomes were compared. The primary outcome was 3-month “favorable o utcome”, defined as modified Rankin Scale score 0...

Proteomics-Based Approach to Identify Novel Blood Biomarker Candidates for Differentiating Intracerebral Hemorrhage From Ischemic Stroke —A Pilot Study
Discussion: In this exploratory proteomics-based pilot study, nine candidate biomarkers for differentiation of IS and ICH were identified. The proteins belong to the immune system, the coagulation cascade, and the apoptosis system, respectively. Further investigations in larger cohorts of patients with stroke using additional biochemical analysis methods, such as ELISA or Western Blotting are now necessary to validate these markers, and to characterize diagnostic accuracy with regard to the development of a point-of-care-system for use in resource-limited areas.

Treatment of patients with mild acute ischemic stroke and associated large vessel occlusion
Publication date: Available online 3 April 2016 Source:Journal of Clinical Neuroscience Author(s): Russell Cerejo, Esteban Cheng-Ching, Ferdinand Hui, M. Shazam Hussain, Ken Uchino, Jennifer Bullen, Gabor Toth Several recent studies have shown that patients presenting with mild acute ischemic stroke (mAIS) symptoms may have an unfavorable natural history. The presence of associated large vessel occlusion (LVO) may lead to even worse outcomes, but most mAIS patients are still excluded from acute stroke treatment (AST). A retrospective review of patients with acute ischemic stroke presenting to our institution betwe...

Modeling and simulation of the modified Rankin Scale and National Institutes of Health Stroke Scale neurological endpoints in intracerebral hemorrhage
AbstractIntracerebral hemorrhage (ICH) is a form of stroke characterized by uncontrolled bleeding into the parenchyma of the brain. There is no approved therapy for ICH and it is associated with very poor neurological outcomes with around half of subjects dying within 1  month and most subjects showing complete or partial disability. A key challenge is to identify subjects who could benefit from intervention using characteristics such as baseline hemorrhage volume and the increase in hemorrhage volume in the first few hours, which have been correlated with final o utcomes in ICH. Combined longitudinal models were develope...

Prospective, open‐label safety study of intravenous recombinant tissue plasminogen activator in wake‐up stroke
ObjectiveIt is estimated that one of four ischemic strokes are noticed upon awakening and are not candidates for intravenous recombinant tissue plasminogen activator (rtPA) because their symptoms are >3 hours from last seen normal (LSN). We tested the safety of rtPA in a multicenter, single‐arm, prospective, open‐label study (NCT01183533) in patients with wake‐up stroke (WUS). MethodsWe aimed to enroll 40 WUS patients with disabling deficits. Patients were 18 to 80 years of age, National Institutes of Health Stroke Scale (NIHSS) ≤25, and selected only on the appearance of noncontrast computed tomography (ie, ove...

Chapter 66 Endovascular treatment of acute ischemic stroke
Publication date: 2016 Source:Handbook of Clinical Neurology, Volume 136 Author(s): Thabele Leslie-Mazwi, James Rabinov, Joshua A. Hirsch Endovascular thrombectomy is an effective treatment for major acute ischemic stroke syndromes caused by major anterior circulation artery occlusions (commonly referred to as large vessel occlusion) and is superior to intravenous thrombolysis and medical management. Treatment should occur as quickly as is reasonably possible. All patients with moderate to severe symptoms (National Institutes of Health stroke scale >8) and a treatable occlusion should be considered. The use of ...

Prognostic parameters for symptomatic intracranial hemorrhage after intravenous thrombolysis in acute ischemic stroke in an Asian population.
Abstract Symptomatic intracranial hemorrhage (sICH) is a major complication after intravenous thrombolysis leading to severe disability and death. The incidence was higher in Asian than in westernized countries. Prognostic factors across ethnicities are presumably different. Studies in Asian populations are limited. Clinical data from January 2008 to September 2016 in one provincial and four regional hospitals in the northern part of Thailand were retrospectively reviewed. Patients were those with acute ischemic stroke, to whom recombinant tissue plasminogen activator (rt-PA) had been prescribed. They were classif...
