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...

Plaque Inflammation in Recently Symptomatic Carotid Stenosis Predicts Recurrent Cerebral Ischemia (P1.233)
Conclusions: FDG-PET/CT and HR-MRI aid in the imaging of plaque inflammation and identification of patients with higher risk of subsequent cerebral ischemic events. This ongoing study intends to develop a robust prediction model for risk stratification based on luminal stenosis and plaque characteristics for better therapeutic decision-making.Disclosure: Dr. Woo has nothing to disclose.

Atherosclerotic Components in Thrombi Retrieved by Thrombectomy for Internal Carotid Artery Occlusion Due to Large Artery Atherosclerosis: A Case Report
Conclusions: Atherosclerotic components in retrieved thrombi might provide useful clues for diagnosing stroke pathogenesis. Further studies are warranted to clarify the utility of assessing atheromatous components in retrieved thrombi in diagnosing stroke etiology.

MR Perfusion in the Evaluation of Mechanical Thrombectomy Candidacy
Stroke is a leading cause of disability and mortality, and the incidence of ischemic stroke is projected to continue to rise in coming decades. These projections emphasize the need for improved imaging techniques for accurate diagnosis allowing effective treatments for ischemic stroke. Ischemic stroke is commonly evaluated with computed tomography (CT) or magnetic resonance imaging (MRI). Noncontrast CT is typically used within 4.5 hours of symptom onset to identify candidates for thrombolysis. Beyond this time window, thrombolytic therapy may lead to poor outcomes if patients are not optimally selected using appropriate...

Multimodality imaging of carotid web: A case report and literature review
CONCLUSIONS: carotid web is an under-recognized cause of ischemic stroke. It is easy to be missed or misdiagnosed. Carotid revascularization can effectively prevent recurrent stroke for patients with symptomatic carotid web. Clinicians should strength their learning and understanding of carotid web.PMID:35306924 | DOI:10.1177/17085381221084809

Acute myocardial infarction related to coronary artery embolism: A systematic cardiac and cerebral magnetic resonance imaging study
CONCLUSION: MI-related to CAE was associated with infarctions of average size but multiple locations. Systematic brain MRI revealed that 33% of cases were associated with a stroke, which was generally asymptomatic. Further studies are required to better characterize the pathophysiology, clinical course and prognostic value of CAE. Moreover, optimal management strategies remain to be determined.PMID:35934614 | DOI:10.1016/j.acvd.2022.05.005

Short-lived middle cerebral artery stenosis and crime atheroma.
CONCLUSION: Intracranial non-stenotic atheroma is a potential cause of a stroke. Our observation support HR-MRI as a tool for the etiology evaluation in young patients with cryptogenic stroke. PMID: 24458856 [PubMed - indexed for MEDLINE]

The Effects of DWI ‐Infarct Lesion Volume on DWI‐FLAIR Mismatch: Is There a Need for Size Stratification?
CONCLUSIONThe effects of stroke onset‐to‐scan time gap on DWI‐FLAIR mismatch are not the same for different DWI lesion volumes. At DWI lesion volumes >15 mL, the DWI‐FLAIR mismatch is highly specific for acute infarcts within IV thrombolytic therapy time, and can identify wake‐up stroke patients eligible for treatment.

No Association between Thrombin Generation and Intra-Plaque Haemorrhage in Symptomatic Carotid Atherosclerotic Plaques: The Plaque at RISK (PARISK) Study.
CONCLUSION:  Features of carotid plaque on MRI show no significant association with TG in stroke patients. Systemic TG does not seem to be an important factor in IPH development. PMID: 29972860 [PubMed - as supplied by publisher]

Thrombolysis Works in Lacunar Infarct, Complicating Imaging Selection
A new, exploratory analysis of the Efficacy and Safety of MRI-Based Thrombolysis in Wake-up Stroke (WAKE-UP) trial by Barow and colleagues in this issue ofJAMA Neurology provides unique and compelling data suggesting that thrombolysis improves clinical outcomes after acute lacunar infarction. The European Union –commissioned, 500-patient, randomized, double-blind, placebo-controlled WAKE-UP trial of alteplase captured the magnetic resonance imaging (MRI) and magnetic resonance angiography of patients with acute ischemic stroke prior to thrombolysis. This allowed categorization of infarcts as lacunar vs n onlacunar, using...

Diagnosis and treatment of acute ischemic insults.
Authors: Diener HC, Wachter R Abstract In cases of stroke a distinction is made between a transient ischemic attack (TIA), a manifest ischemic infarction and cerebral hemorrhage. Cerebral ischemia can be caused by large vessel disease, small vessel disease, embolic causes, rare causes or stroke of unknown etiology. Acute diagnostic tests include a neurological examination, computed tomography (CT) and/or magnetic resonance imaging (MRI) with angiography, electrocardiography (ECG), and laboratory tests. The basic treatment of patients with TIA or acute ischemic infarction is performed in the stroke unit and include...

Inflammation May Be the Culprit Behind Our Deadliest Diseases
In the early days of my medical residency, I met a man whom we’ll call Jason. He arrived to our emergency room on a holiday, nonchalant yet amiable, and complained of mild chest pain. Jason was tall and trim, with a strong South Boston accent and fingertips still faintly stained from his last home-improvement project. He was only 45 years old, but he looked much younger. He didn’t smoke, barely drank alcohol, and his cholesterol levels had always been normal. No one in his family had a history of heart disease. He asked us if we could work quickly—he wanted to be home for dinner with his daughters. [time-...
