Dynamic Detection of Thrombolysis in Embolic Stroke Rats by Synchrotron Radiation Angiography
AbstractA rodent model of embolic middle cerebral artery occlusion is used to mimic cerebral embolism in clinical patients. Thrombolytic therapy is the effective treatment for this ischemic injury. However, it is difficult to detect thrombolysis dynamically in living animals. Synchrotron radiation angiography may provide a novel approach to directly monitor the thrombolytic process and assess collateral circulation after embolic stroke. Thirty-six adult Sprague-Dawley rats underwent the embolic stroke model procedure and were then treated with tissue plasminogen activator. The angiographic images were obtained in vivo by s...

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.

Talk About Thrombolysis. Regular Case-Based Discussions of Stroke Thrombolysis Improve Door-to-Needle Time by 20%.
Background: The outcome of stroke patients can be improved by a rapid initiation of thrombolytic therapy. Here, we sought to determine whether an additional simple but thorough case-based discussion of recent thrombolysed cases with the entire neurologic staff can improve the door-to-needle time without changes to the implemented stroke protocol. Methods: For every performed thrombolysis, a route card, consisting of a timeline with 3 time points and target times, had to be completed by the attending neurologist.

Preclinical Validation of the Therapeutic Potential of Glasgow Oxygen Level Dependent (GOLD) Technology: a Theranostic for Acute Stroke
AbstractIn acute stroke patients, penumbral tissue is non-functioning but potentially salvageable within a time window of variable duration and represents target tissue for rescue. Reperfusion by thrombolysis and/or thrombectomy can rescue penumbra and improve stroke outcomes, but these treatments are currently available to a minority of patients. In addition to the utility of Glasgow Oxygen Level Dependent (GOLD) as an MRI contrast capable of detecting penumbra, its constituent perfluorocarbon (PFC) oxygen carrier, combined with normobaric hyperoxia, also represents a potential acute stroke treatment through improved oxyg...

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.

MMP10 Promotes Efficient Thrombolysis After Ischemic Stroke in Mice with Induced Diabetes
AbstractDiabetes is an important risk factor for ischemic stroke (IS). Tissue-type plasminogen activator (tPA) has been associated with less successful revascularization and poor functional outcome in diabetes. We assessed whether a new thrombolytic strategy based on MMP10 was more effective than tPA in a murine IS model of streptozotocin (STZ)-induced diabetes. Wild-type mice were administered a single dose of streptozotocin (STZ) (180  mg/kg) to develop STZ-induced diabetes mellitus. Two weeks later, IS was induced by thrombin injection into the middle cerebral artery and the effect of recombinant MMP10 (6.5 μg/kg), t...

Acute Stroke Patients With Mild-to-Moderate Pre-existing Disability Should Be Considered for Thrombolysis Treatment
Thrombolytic therapy in patients with pre-existing disability presenting with acute ischemic stroke (AIS) is controversial because of concerns regarding poor outcomes and futility of treatment. We hypothesized that a similar proportion of patients with and without pre-existing disability would return to their premorbid functional status following thrombolysis.

Similar Outcomes for Contact Aspiration and Stent Retriever Use According to the Admission Clot Burden Score in ASTER Clinical Sciences
Conclusions—First-line mechanical thrombectomy with contact aspiration compared with stent retriever did not result in an increased successful reperfusion rate in acute ischemic stroke patients with large vessel occlusion of the anterior circulation according to the admission CBS. The latter, however, seems to be a reliable prognostic indicator of angiographic and clinical outcome.

Thrombolytic Therapy in Severe Cardioembolic Stroke After Reversal of Dabigatran with Idarucizumab: Case Report and Literature Review
Whether idarucizumab, an antidote of dabigatran, can be used effectively and safely before thrombolytic therapy with recombinant tissue plasminogen activator (rt-PA) in patients with stroke undergoing treatment with dabigatran remains unknown. We herein describe a 57-year-old man who developed severe cardioembolic stroke with a National Institutes of Health Stroke Scale score of 22 in the left middle cerebral artery territory while undergoing treatment with dabigatran for nonvalvular atrial fibrillation and who was treated with rt-PA after the reversal of dabigatran with idarucizumab.

Drip-and-Ship Thrombolytic Therapy for Acute Ischemic Stroke
Neuroendovascular therapy is a common treatment for patients with acute ischemic stroke of the anterior circulation who fail to respond to recombinant tissue plasminogen activator. However, although most hospitals can provide recombinant tissue plasminogen activator therapy, many cannot perform neuroendovascular therapy. Thus, use of a drip-and-ship treatment-liaison system allowing recombinant tissue plasminogen activator-treated patients to be transferred to facilities offering neuroendovascular therapy is important.

Recurrent Stroke Due to Metastatic Pulmonary Tumor Emboli as an Important Clinical Entity
We present an autopsy case of repetitive stroke due to tumor emboli, indistinguishable from thromboembolism with a hypercoagulable state in its clinical course. A 72-year-old man diagnosed with stage IVA oropharyngeal squamous cell carcinoma received chemoradiotherapy. Follow-up imaging revealed mediastinal lymph nodes and pulmonary metastasis. One year later, the patient experienced right arm weakness, and brain magnetic resonance imaging showed acute ischemic lesions in multiple vascular territories.
