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

Extracranial carotid plaque hemorrhage predicts ipsilateral stroke recurrence in patients with carotid atherosclerosis - a study based on high-resolution vessel wall imaging MRI
CONCLUSIONS: Carotid intraplaque hemorrhage is strongly associated with recurrent ischemic events and could predict recurrent ipsilateral stroke.PMID:35764942 | DOI:10.1186/s12883-022-02758-3

Modern Treatment of Asymptomatic Carotid Stenosis —The Importance of Both Medical Therapy and Carotid Endarterectomy
Each year there are approximately 700 000 new ischemic strokes in the US, and 10% to 15% of them are caused by thromboembolism from a previously asymptomatic carotid stenosis (ACS). Three large randomized clinical trials, published in the 1990s and early 2000s, have demonstrated a significant benefit of carotid endarterectomy (CEA) i n preventing stroke in patients with severe ACS compared with medical therapy alone. They showed a 50% relative risk reduction in 5-year stroke rate and an approximately 1% per year absolute stroke risk reduction. Over the course of the past 2 decades, there has been significant improvement...

Carotid Plaque Composition and the Importance of Non-Invasive in Imaging Stroke Prevention
Front Cardiovasc Med. 2022 May 16;9:885483. doi: 10.3389/fcvm.2022.885483. eCollection 2022.ABSTRACTLuminal stenosis has been the standard feature for the current management strategies in patients with atherosclerotic carotid disease. Histological and imaging studies show considerable differences between plaques with identical degrees of stenosis. They indicate that specific plaque characteristics like Intraplaque hemorrhage, Lipid Rich Necrotic Core, Plaque Inflammation, Thickness and Ulceration are responsible for the increased risk of ischemic events. Intraplaque hemorrhage is defined by the accumulation of blood compon...

Paradoxical venous air embolism detected with point-of-care ultrasound: a case report
We present a case of a critical care patient who presented sudden clinical hemodynamic deterioration after the removal of central venous catheter. Hemodynamic evaluation with point-of-care ultrasound (POCUS) showed bubbles in both right and left heart cavities wherewith air embolism facilitated by heart septal defect was suspected. Therefore, the patient was reintubated, supported with vasopressors and a new CVC was inserted to proceed with air aspiration. Shortly after, the patient ’s hemodynamic status improved in terms of vital signs stabilization. 6 h after the event with optimal perfusion markers and diminished sed...

A concise guide to transtemporal contrast-enhanced ultrasound in children
AbstractBrain contrast-enhanced ultrasound offers insights into the brain beyond the anatomic information offered by conventional grayscale ultrasound. In infants, the open fontanelles serve as acoustic windows. In children, whose fontanelles are closed, the temporal bone serves as the ideal acoustic window due to its relatively smaller thickness than the other skull bones. Diagnosis of common neurologic diseases such as stroke, hemorrhage, and hydrocephalus has been performed using the technique. Transtemporal ultrasound and contrast-enhanced ultrasound, however, are rarely used in children due to the prevalent notion tha...

Concurrent subarachnoid haemorrhage and internal carotid artery dissection: a transcranial colour-coded sonography diagnosis
We report the case of a young woman affected by an aneurysmal subarachnoid haemorrhage (SAH) and numerous anatomic abnormalities. A Transcranial Colour-Coded Duplex Sonography, performed with the aim of monitoring the vasospasm, showed a non-pulsatile flow with loss of sharp systolic peak and lowering of mean flow velocities in the right extracranial Internal Carotid Artery (ICA) and all its intra-cranial branches. This event suggested a possible concomitant acute right ICA sub-occlusion with a lack of collateral circulation. This type of flow is typically found in systemic and brain arteries of patients undergoing to veno...

Ultrasound Perfusion Imaging for the Detection of Cerebral Hypoperfusion After Aneurysmal Subarachnoid Hemorrhage
ConclusionsUPI is feasible to enable detection of cerebral tissue hypoperfusion after aSAH, and the left –right difference of TTP values is the most indicative result of this finding.

Ultrasound-Induced Release of Nimodipine from Drug-Loaded Block Copolymer Micelles: In Vivo Analysis
In this study, we aimed to assess the concept of controlled drug release from nimodipine-loaded copolymers by ultrasound application in the chicken chorioallantoic membrane (CAM) model. Nimodipine-loaded copolymers were produced with the direct dissolution method. Vasospasm of the CAM vessels was induced by means of ultrasound (Physiomed, continuous wave, 3 MHz, 1.0 W/cm2). The ultrasound-mediated nimodipine release (Physiomed, continuous wave, 1 MHz, 1.7 W/cm2) and its effect on the CAM vessels were evaluated. Measurements of vessel diameter before and after ultrasound-induced nimodipine release were performed using...

Changes in muscle architecture on ultrasound in patients early after stroke
CONCLUSIONS: We report changes in ultrasound-derived muscle architecture in the hemiplegic limbs of patients with subacute stroke, with consistent findings of decreased muscle mass and increased echo intensity.PMID:34806627 | DOI:10.3233/NRE-210257
