Hyperacute stenting and angioplasty for acute extracranial non-tandem internal carotid artery strokes within the first 48 h: A 20-year experience and a systematic review and meta-analysis
CONCLUSION: Stenting and angioplasty for acute cervical ICA occlusive strokes during the hyperacute phase can be performed successfully with favorable clinical outcomes and an acceptable recanalization rate.PMID:37218164 | DOI:10.1177/15910199231164510

Using a CT Angiography Artificial Intelligence Carotid Plaque Morphology Model to Predict Stroke
The gold standard for determining carotid artery stenosis is to calculate stenosis using the North American Symptomatic Carotid Endarterectomy Trial criteria and ultimately plan for medical vs surgical management based on percent stenosis and symptomatic status. Few studies have assessed plaque morphology as an additive tool for stroke prediction. Our study uses an artificial intelligence software in conjunction with a patient's computed tomography (CT) scan of the neck to create a three-dimensional (3D) model of the carotid artery and assess plaque morphology including calcification, intraplaque hemorrhage, matrix, and pe...

Diagnostic Value of Vessel Wall Imaging to Determine the Timing of Extracranial ‒Intracranial Bypass for Moyamoya Syndrome Associated with Active Sjögren's Syndrome: A Case Report
Conclusions Our findings emphasize the diagnostic value of contrast-enhanced MR-VWI in monitoring the effect of immunosuppressive therapy for the major cerebral artery vasculitis and in determining the timing of EC–IC bypass as a “rescue” treatment for moyamoya syndrome associated with active Sjögren's syndrome.

Stroke and molecular imaging: a focus on FDG-PET
Am J Nucl Med Mol Imaging. 2023 Apr 25;13(2):51-63. eCollection 2023.ABSTRACTStroke is the leading cause of disability worldwide, the second most common cause of dementia and the third leading cause of death. Though the etiology of stroke has been explored extensively, there remains open questions in the scientific and clinical study of stroke. Traditional imaging techniques, such as magnetic resonance imaging and computed tomography, have been applied extensively and remain mainstays in clinical practice. Nevertheless, positron emission tomography has proven to be a powerful molecular imaging tool in exploring the scienti...

Case report: Bilateral sudden deafness in acute middle cerebellar peduncle infarction: central or peripheral?
CONCLUSION: Vertebrobasilar diseases due to atherosclerosis should be routinely considered in middle-aged and elderly patients with vascular risk factors and bilateral hearing loss. Bilateral SSNHL can be a prodrome of acute MCP infarction and it can be peripheral. Brain MRI, brain magnetic resonance angiogram (MRA), brain and neck computed tomography angiography (CTA), BAEP, otoacoustic emissions, and Pure Tone Audiogram help to localize and qualify the diagnosis. Bilateral SSNHL localized to the periphery usually improves better and has a good prognosis. Early detection of hearing loss and intervention can help patients ...

Association between dietary antioxidant capacity and atherosclerotic carotid stenosis in patients with ischemic stroke
CONCLUSIONS: DTAC may influence the initiation and development of atherosclerosis, and, therefore, the risk of ischemic stroke.PMID:37210776 | DOI:10.1016/j.jstrokecerebrovasdis.2023.107148

The Great Contrast Shortage of 2022 —Lessons learnt in Australia
ConclusionOur findings demonstrate that the IBCM shortage crisis had a very significant impact on the delivery of healthcare. While V/Q scans could (partially) substitute for CTPA studies in suspected pulmonary emboli, there appeared to be no valid alternative for CTNA studies in stroke calls. The unexpected and critical shortage of IBCM forced healthcare professionals to conserve resources, prioritise indications, triage patients based on risk, explore alternate imaging strategies and prepare for similar events recurring in the future.

Establishing a pediatric acute stroke protocol: experience of a new pediatric stroke program and predictors of acute stroke
ConclusionA trainee developed and initiated pediatric acute stroke protocol quickly implemented a hospital wide change in management that led to rapid diagnosis and triage of pediatric stroke and suspected stroke. No additional personnel or resources were needed for this change, and we encourage other hospitals and emergency departments to implement similar systems. Additionally, hemiparesis and altered mental status were predictors of stroke for pediatric acute stroke activation in our Bayesian statistical analysis. However credible intervals were wide due to the small sample size. Further multicenter data collection coul...

Minimally Invasive Intracerebral Hemorrhage Evacuation Improves Pericavity Cerebral Blood Volume
This study aims to quantify blood volume changes in the perihematomal parenchyma and pericavity parenchyma after minimally invasive intracerebral hemorrhage evacuation (MIS for ICH). Thirty-two patients underwent MIS for ICH with pre- and post-operative CT imaging and intraoperative perfusion imaging (DynaCT PBV Neuro, Artis Q, Siemens). The pre-operative and post-operative CT scans were segmented using ITK-SNAP software to calculate hematoma volumes and to delineate the pericavity tissue. Helical CT segmentations were registered to cone beam CT data using elastix software. Mean blood volumes were computed inside subvolume...

Stroke Thrombectomy through Interstices of a Hybrid Endograft Placed for Type A Aortic Dissection
A 53-year-old man presented with acute, severe, thoracic pain, absence of the femoral and left radial pulses, and asymmetric blood pressure —80/40 mm Hg in the left arm and 170/110 mm Hg in the right arm. Contrast-enhanced computed tomography revealed type A aortic dissection, starting from the aortic valve and extending into both iliac arteries (Fig 1). Emergent hemiarch replacement surgery was performed, with insertion of a hybrid a ortic stent with a proximal felt sewing cuff (Ascyrus Medical Dissection Stent, [AMDS]; Ascyrus Medical, Frankfurt, Germany) into the aortic arch with reimplantation of the brachiocephalic ...

The role of intracranial artery calcification (IAC) in stroke subtype and risk of vascular events
CONCLUSION: In these multiethnic populations, IAC is associated with symptomatic and asymptomatic ILAS as well as higher mortality. IAC may be a useful marker of higher mortality, the role of IAC as an imaging marker of risk of stroke is less certain.PMID:37186970 | DOI:10.1016/j.jstrokecerebrovasdis.2023.107185

Association Between Spotty Calcification in Nonstenosing Extracranial Carotid Artery Plaque and Ipsilateral Ischemic Stroke
Conclusions Spotty calcifications associated with low-density plaque and maximum plaque thickness were associated with ipsilateral ischemic stroke in patients with nonstenotic carotid atherosclerosis, suggesting a role as imaging markers of high-risk plaque.PMID:37183863 | DOI:10.1161/JAHA.122.028525

CSF-Based Volumetric Imaging Biomarkers Highlight Incidence and Risk Factors for Cerebral Edema After Ischemic Stroke
ConclusionsCerebral edema can be measured in a majority of patients with stroke on follow-up computed tomography using volumetric biomarkers evaluating CSF shifts, including in many without visible midline shift. Edema formation is influenced by clinical and radiographic stroke severity but also by chronic vascular risk factors and contributes to worse stroke outcomes.
