Carotid Artery Free-Floating Thrombus Caused by Paradoxical Embolization From Greater Saphenous Vein Ascending Thrombophlebitis
We report a case of a young woman without cardiovascular risk factors who was admitted to our emergency department with listlessness and altered mental status. The clinical examination revealed right lower limb swelling. Magnetic resonance imaging and contrast-enhanced computed tomographic scans revealed a free floating thrombus of the left internal carotid artery (ICA) with a large bilateral frontal ischemic lesion. The diagnosis of a medium-sized PFO with moderate right-to-left contrast shunting was made after transesophageal echocardiography. No other cardiac sources for embolization were detected, while an ascending th...

Reducing Resource Utilization and Improving Efficiency Using A Separate Activation for Emergent Large Vessel Occlusion Ischemic Strokes (P5.264)
Conclusions:Partitioning of the acute stroke management process with a separate activation for probable large vessel occlusions resulted in a reduction of vascular imaging utilization and did not result in slower door-to-groin times.Study Supported by: No funding.Disclosure: Dr. Tan has nothing to disclose.

Transcranial Doppler Screening in a Regional Care Network for Sickle Cell Disease in the United Kingdom
The risk of stroke in children screened with transcranial Doppler ultrasound in the United Kingdom is not known. We evaluated a clinician-led program using a risk assessment modified from the STOP protocol. High-risk classification included abnormal velocities in the anterior cerebral artery, and single abnormal scan if initial velocity>220 cm/s (high abnormal) or if preceded by at least 2 conditional scans. In total, 1653 scans were performed in 542 children, followed for 2235 patient-years. Fifty-eight (10.7%) high-risk subjects were identified, including 18 (31%) with high abnormal, and 15 (26%) with previous conditiona...

More to Atherosclerosis than Stenosis: Symptomatic Carotid Artery with Intraplaque Hemorrhage (P5.285)
Conclusions:Current guidelines only address the degree of arterial narrowing when recommending carotid revascularization procedures for secondary stroke prevention. The most recent AHA-ASA guideline advises against revascularization procedures in less than 50% CA stenosis. These guidelines do not account for plaque morphology that may predict a high risk of early stroke recurrence as demonstrated by our patient.Disclosure: Dr. Rai has nothing to disclose.

Changes in blood volume indicators and dynamic indicators measured with transpulmonary ultrasound velocity during blood depletion and repletion in a neonatal swine model
ConclusionTotal end‐diastolic volume and central blood volume changed during blood depletion and repletion, and differed between stages of hemorrhage. These indicators might be useful for assessing volume status instead of, or in addition to cardiac index and dynamic indicators.

A Little Good...
Abstract
My grandmother used to say: "If a little'll do a little good, a lot'll do a lotta good." Unfortunately, it is not that simple with antiplatelet agents. Many relevant facts are well-established. In identifiable subgroups of patients who present with TIA or minor stroke, the risk of a subsequent stroke is high.(1-3) Most of this risk is incurred during the first few days after a warning event.(2) Aspirin and other antiplatelet agents can lower the risk of secondary stroke by approximately 12-22%.(4,5) In patients with acute coronary syndromes, another thrombotic disorder, dual antiplatelet therapy offers a ...

Intracranial Arterial Dissection (P2.013)
CONCLUSIONS:IAD represent a substantial proportion of CAD and may be a frequently underdiagnosed cause of stroke. Intraparenchymal hemorrhage seemed to occur less frequently in our series than previously reported.Study Supported by:Disclosure: Dr. Dossi has nothing to disclose.

Non-invasive Carotid Artery Imaging to Identify the Vulnerable Plaque: Current Status and Future Goals.
CONCLUSION: MRI has demonstrated the most potential, with good sensitivity and specificity for most plaque characteristics. However, currently there is no single imaging modality that can reliably identify the vulnerable plaque in relation to development of future stroke.

Chapter 55 Vascular imaging
Publication date: 2016 Source:Handbook of Clinical Neurology, Volume 136 Author(s): David Rodriguez-Luna, Carlos A. Molina The complexity of current stroke treatments requires detailed vascular imaging information. Vascular imaging using ultrasound is a safe, inexpensive, and portable technique that provides continuous real-time hemodynamic information, which allows flow changes to be monitored over prolonged time. Ultrasound imaging is in continuous development, which has led to a growing number of situations where ultrasound can be helpful, foremost in dynamic and rapidly changing clinical scenarios like acute stroke...

E-021 Safety and efficacy of a low dose eptifibatide infusion during endovascular treatment of tandem occlusions
Conclusions
The low dose eptifibatide infusion resulted in a low incidence of SICH (5%) in the endovascular treatment of tandem intracranial occlusions. The infusion was not potent enough to maintain patency of the carotid artery in all patients. However, re-occlusion of the carotid artery was asymptomatic in the 4 patients where it occurred. This underscores that extracranial re-occlusion of the carotid artery is the lesser of evils compared with hemorrhagic stroke conversion. Limitations of the study include retrospective data collection, a low incidence of intravenous t-PA use, and lack of independent adjudication of an...

Circulating Microparticles in Patients with Symptomatic Carotid Disease Are Related to Embolic Plaque Activity and Recent Cerebral Ischaemia
Conclusions: PMP and EMP were associated with stroke and recent cerebrovascular events (DWI+) but only PMP were also associated with ongoing (MES+) thrombo-embolic activity suggesting a differential biomarker potential for EMP to index cerebral ischaemia while PMP may predict on-going thrombo-embolic activity.Cerebrovasc Dis Extra 2019;9:9 –18

Anticoagulant management by low-dose of low molecular weight heparin in patients with nonvalvular atrial fibrillation following hemorrhagic transformation and complicated with venous thrombosis: Five case reports and literature review
For patients with nonvalvular atrial fibrillation (NVAF) following hemorrhagic infarction (HI)/hemorrhage transformation (HT) and complicated with venous thrombosis, the management of anticoagulation is controversial. Our study intends to explore the safety and effectiveness of using low-dose of low molecular weight heparin (LMWH) to treat NVAF patients with HI (or HT) and complicated with venous thrombosis.
Between January 2018 and January 2019, NVAF related acute ischemic stroke patients with HT/HI, hospitalized in the department of neurology or rehabilitation in our hospital, are enrolled retrospectively. Among them,...

Diagnostic accuracy of neuroimaging in emergency department patients with acute vertigo or dizziness: A systematic review and meta-analysis for the Guidelines for Reasonable and Appropriate Care in the Emergency Department
CONCLUSION: Non-contrast CT has very low sensitivity and MRI will miss approximately one in five patients with stroke if imaging is obtained early after symptom onset. Neuroimaging should not be used as the only tool for ruling out stroke and other central causes in patients with acute dizziness or vertigo presenting to the ED.PMID:35876220 | DOI:10.1111/acem.14561

The Development of Neuroimaging Biomarkers for Cognitive Decline in Sickle Cell Disease
Sickle cell disease (SCD) is complicated by neurologic complications including vasculopathy, hemorrhagic or ischemic overt stroke, silent cerebral infarcts and cognitive dysfunction. Patients with SCD, even in the absence of vasculopathy or stroke, have experience cognitive dysfunction that progresses with age. Transcranial Doppler ultrasound and structural brain MRI are currently used for primary and secondary stroke prevention, but laboratory or imaging biomarkers do not currently exist that are specific to the risk of cognitive dysfunction in patients with SCD. Recent investigations have used advanced MR sequences asses...
