E-152 Cone-beam CT angiogram acquisition in the angiography suite for LVO detection in acute ischemic stroke
ConclusionDTAS triage workflow with cone-beam head CT and CTA image acquisition in the angiography suite may be a next step to further optimize LVO stroke pathways by bypassing conventional CT/MR. This new workflow has the potential to further decrease door-to-needle times and thereby may improve patient outcome.Disclosures A. Kuhn: None. J. Singh: None. M. Garcia: None. S. Sarid: None. M.

Traumatic vertebral artery injury: Denver grade, bilaterality, and stroke risk. A systematic review and meta-analysis
CONCLUSIONS: VAI complicates a small yet nontrivial fraction of blunt trauma cases, with Denver grade IV lesions being the most common. This is the first study to document a significantly higher stroke prevalence among grade III and IV VAIs compared with grade I and II VAIs independently from bilaterality. Bilateral VAIs carry a significantly higher stroke rate.PMID:37548568 | DOI:10.3171/2023.5.JNS222818

Value of CT angiography in anterior circulation large vessel occlusive stroke: Imaging findings, pearls, and pitfalls
Publication date: July 2015 Source:European Journal of Radiology, Volume 84, Issue 7 Author(s): Sarah Power , Sinead H. McEvoy , Jane Cunningham , Joanna P. Ti , Seamus Looby , Alan O'Hare , David Williams , Paul Brennan , John Thornton Hyperacute stroke imaging is playing an increasingly important role in determining management decisions in acute stroke patients, particularly patients with large vessel occlusive stroke who may benefit from endovascular intervention. CT angiography (CTA) is an important tool in the work-up of the acute stroke patient. It reliably detects large occlusive thrombi in proximal cerebral arter...

A pragmatic approach to sonothrombolysis in acute ischaemic stroke: the Norwegian randomised controlled sonothrombolysis in acute stroke study (NOR-SASS)
DiscussionNOR-SASS is the first randomised controlled trial designed to test the superiority of contrast enhanced ultrasound treatment given ≤4½ hours after stroke onset in an unselected acute ischaemic stroke population eligible or not eligible for intravenous thrombolysis, with or without a defined arterial occlusion on CTA. If a positive effect and safety can be proven, contrast enhanced ultrasound treatment will be an option for all acute ischaemic stroke patients.

HEart and BRain interfaces in Acute ischemic Stroke (HEBRAS) – rationale and design of a prospective oberservational cohort study
DiscussionBy comparing the results of routine diagnostic care to the study-specific MRI/ECG approach, the primary outcome of HEBRAS is the proportion of stroke patients with pathologic diagnostic findings. Predefined secondary outcomes are the association of stroke localization, autonomic dysbalance and cardiac dysfunction as well as the effect of impaired heart-rate-variability on long-term clinical outcome.The investigator-initiated HEBRAS study will assess whether an enhanced MRI approach and a prolonged ECG monitoring yield a higher rate of pathological findings than current standard diagnostic care to determine stroke...

Stroke Mimics in a Stroke Care Pathway Based on MRI Screening
Conclusions: A rate of SM up to 38% of the code stroke system confirms the difficulty to distinguish clinically a stroke from another diagnosis. In this study, using cerebral MRI in first intention was of special interest in patients with acute neurological symptoms to differentiate an NVD from an SM.Cerebrovasc Dis 2016;42:205-212

Prediction of Large Vessel Occlusions in Acute Stroke: National Institute of Health Stroke Scale Is Hard to Beat*
Objectives: Endovascular treatment for acute ischemic stroke with a large vessel occlusion was recently shown to be effective. We aimed to develop a score capable of predicting large vessel occlusion eligible for endovascular treatment in the early hospital management. Design: Retrospective, cohort study. Setting: Two tertiary, Swiss stroke centers. Patients: Consecutive acute ischemic stroke patients (1,645 patients; Acute STroke Registry and Analysis of Lausanne registry), who had CT angiography within 6 and 12 hours of symptom onset, were categorized according to the occlusion site. Demographic and clinical informati...

Acute Ischemic Stroke as a Presenting Feature of Multiple Myeloma (P3.279)
Conclusions:Stroke is a leading and preventable cause of disability in the US adult population. The majority of strokes are due to atherosclerotic vascular or cardioembolic disease. Understanding the diagnostic work up of stroke and recognizing rare etiologies like MM is important for stroke prevention. This brings to light the importance of recognizing stroke as an initial presenting feature of multiple myeloma and of multiple myeloma as an important treatable etiology of stroke.Disclosure: Dr. Chung has nothing to disclose.

Update on Neurocritical Care of Stroke
AbstractPurpose of ReviewThis review will highlight the recent advancements in acute ischemic stroke diagnosis and treatment, with special attention to new features and recommendations of stroke care in the neurocritical care unit.Recent FindingsNew studies suggest that pre-hospital treatment of stroke with mobile stroke units and telestroke technology may lead to earlier stroke therapy with intravenous tissue plasminogen activator (tPA), and recent studies show tPA can be given in previously contraindicated situations. More rapid automated CT perfusion and angiography may demonstrate a vascular penumbra for neuroendovascu...

P-016 Relationship between stroke recurrence, infarct pattern, and vascular distribution in patients with symptomatic intracranial stenosis
Conclusion We determined that basilar artery stenosis was most likely to present as a perforator stroke. As expected, patients discharged with suboptimal medical therapy were twice as likely to have a recurrent stroke (29% versus 13%). Among patients with optimal medical therapy, no recurrent strokes were seen in patients with embolic infarct pattern, while 57% recurrence rate was seen in patients with a watershed infarct pattern, suggesting that an embolic infarct pattern on initial presentation is possibly related to underlying plaque instability that is modifiable with optimal medical therapy. On the other hand, initial...

Relationship between the stroke mechanism of symptomatic middle cerebral artery atherosclerotic diseases and culprit plaques based on high-resolution vessel wall imaging
ConclusionThe culprit plaque characteristics of patients with symptomatic MCA atherosclerotic in different stroke mechanisms may be evaluated using HR-VWI. The plaque characteristics of different stroke mechanisms may have clinical value for the selection of treatment strategies and prevention of stroke recurrence.Clinical trial registrationIdentifier: ChiCTR1900028533.
