Intravenous Thrombolysis in Acute Ischemic Stroke After Idarucizumab Reversal of Dabigatran Effect: Analysis of the Cases From Taiwan
Background: Asians with atrial fibrillation carry a higher risk of ischemic stroke than non-Asians even under treatment of nonvitamin K antagonist oral anticoagulants. The purpose of the study was to observe the feasibility of intravenous thrombolytic therapy after administering a reversal agent, idarucizumab, in dabigatran-treated patients with acute ischemic stroke in Taiwan. Methods: Dabigatran-treated patients with acute ischemic stroke who received intravenous recombinant tissue plasminogen activator (rt-PA) after idarucizumab reversal were enrolled in the retrospective nationwide study.

Clinical Characteristics of Stroke with COVID-19: A Systematic Review and Meta-Analysis
The coronavirus disease 2019 (COVID-19) potentially increases the risk of thromboembolism and stroke. Numerous case reports and retrospective cohort studies have been published with mixed characteristics of COVID-19 patients with stroke regarding age, comorbidities, treatment, and outcome. We aimed to depict the frequency and clinical characteristics of COVID-19 patients with stroke.

Per-pass analysis of acute ischemic stroke clots: impact of stroke etiology on extracted clot area and histological composition
Conclusion LAA clots are larger and associated with a large red blood cell-rich extracted clot area, suggesting soft thrombus material. Cardioembolic clots are smaller in the extracted clot area, consistent in composition and area across passes, and have higher fibrin and platelets/other content than LAA clots, making them stiffer clots. The per-pass histological composition and extracted clot area of cryptogenic clots are similar to those of cardioembolic clots, suggesting similar formation mechanisms.

Moving from traditional to more advanced treatments in stroke care is cost-effective: A case study from Greece
Ischemic stroke (IS) is one of the leading causes of mortality and disability,1, 2 with the economic burden of post-stroke care being substantial.1, 2 After incidence of IS, the following effective treatments have been found to significantly improve survival and quality of life: (a) treatment in specialized centres (Stroke Units; SU), (b) use of intravenous thrombolytic therapy (IVT), (c) use of endovascular thrombectomy (EVT) for patients with large vessel occlusions (LVO) and (d) rehabilitation.

The Effects of Alteplase 3 to 6 Hours After Stroke in the EPITHET-DEFUSE Combined Dataset: Post Hoc Case-Control Study Original Contributions
Conclusions— The data provide further evidence that alteplase significantly attenuates infarct growth and increases reperfusion compared with placebo in the 3- to 6- hour time window in patients selected based on MR penumbral imaging.

Speed Vital For Stroke Patients' Survival
The sooner stroke patients receive thrombolytic treatment, the lower their risk of in-hospital mortality and intracranial hemorrhage, says a new study published in JAMA (Journal of the American Medical Association). In addition, the prompter the treatment, the higher the rate of walking ability at discharge. Intravenous (IV) tissue-type plasminogen activator (tPA) is a form of treatment proven to help stroke patients within 4.5 hours of onset of symptoms...

Earlier Treatment Following Stroke Onset Associated With Reduced Risk Of In-Hospital Death, Higher Rate Of Discharge To Home
In a study that included nearly 60,000 patients with acute ischemic stroke, thrombolytic treatment (to help dissolve a blood clot) that was started more rapidly after symptom onset was associated with reduced in-hospital mortality and intracranial hemorrhage and higher rates of independent walking ability at discharge and discharge to home, according to a study in the June 19 issue of JAMA. "Intravenous (IV) tissue-type plasminogen activator (tPA) is a treatment of proven benefit for select patients with acute ischemic stroke as long as 4.5 hours after onset...

Validating Imaging Biomarkers of Cerebral Edema in Patients With Severe Ischemic Stroke
Background: There is no validated neuroimaging marker for quantifying brain edema. We sought to test whether magnetic resonance imaging (MRI)–based metrics would reliably change during the early subacute period in a manner consistent with edema and whether they would correlate with relevant clinical endpoints.Methods: Serial MRI studies from patients in the Echoplanar Imaging Thrombolytic Evaluation Trial with initial diffusion-weighted imaging (DWI) lesion volume>82 cm3 were analyzed. Two independent readers outlined the hemisphere and lateral ventricle on the involved side and calculated respective volumes at baseline...

Translational perspectives on perfusion–diffusion mismatch in ischemic stroke
Magnetic resonance imaging has tremendous potential to illuminate ischemic stroke pathophysiology and guide rational treatment decisions. Clinical applications to date have been largely limited to trials. However, recent analyses of the major clinical studies have led to refinements in selection criteria and improved understanding of the potential implications for the risk vs. benefit of thrombolytic therapy. In parallel, preclinical studies have provided complementary information on the evolution of stroke that is difficult to obtain in humans due to the requirement for continuous or repeated imaging and pathological veri...

National Survey of Thrombolytic Therapy for Acute Ischemic Stroke in Taiwan 2003-2010
Data on thrombolytic therapy at the national level is scarce in Asia. Understanding current practice pattern is important for a policy maker in decision making. This cross-sectional study analyzed the utilization pattern of thrombolytic therapy for acute ischemic stroke (AIS) in Taiwan from 2003 through 2010 and identified factors associated with post-therapy intracerebral hemorrhage (ICH) and mortality. From the Taiwan National Health Insurance Research Database, we retrieved inpatient claims for patients with AIS. The frequency of thrombolytic therapy in AIS admissions and its association with the characteristics of pati...

Predictors of In-hospital Mortality and the Risk of Symptomatic Intracerebral Hemorrhage after Thrombolytic Therapy with Recombinant Tissue Plasminogen Activator in Acute Ischemic Stroke
This study aimed to determine the independent predictors of in-hospital mortality (IHM) and the risk of sICH after rt-PA therapy. A total of 1007 patients (mean age, 72 ± 12 years; 52% women; mean National Institutes of Health Stroke Scale [NIHSS] score, 11.6 ± 5.6) with AIS treated with rt-PA were enrolled in this study during a 42-month period beginning in November 2007. Univariate and multivariate regression analyses were performed to estimate the predictors of IHM. Eighty-three of the 1007 patients (8.2%) died during hospitalization (mean duration of hospitalization, 10 ± 1.8 days). Logistic regression estimated the...

Fluorescent Molecular Peroxidation Products: A Prognostic Biomarker of Early Neurologic Deterioration After Thrombolysis Clinical Sciences
Conclusions— FMPPs might be a valuable biomarker of poor early neurological outcome and be related to the appearance of symptomatic intracranial hemorrhage in tissue plasminogen activator–treated patients, one of the most feared neurological complications after thrombolytic treatment of acute ischemic stroke.

Cryptogenic Stroke and the Left Atrial Septal Pouch: A Case Report
We present the case of a 49 year-old man without known vascular risk factors who experienced bi-hemispheric strokes over the course of 10 days, suggestive of multiple emboli. Transesophageal echocardiography revealed a prominent LASP. We suggest that presence of LASP was a likely cause of stroke in this patient and that further study of a possible association between LASP and ischemic stroke in younger individuals may be warranted.

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.
