Acute ischemic stroke diagnosis using brain tissue pulsations

This study is the first to explore the clinical potential of measuring BTPs using ultrasound in acute ischemic stroke patients.BTPs were measured in 24 healthy volunteers (aged 52 –82 years) and 14 acute ischemic stroke patients (aged 51–86 years) using a novel Transcranial Tissue Doppler (TCTD) method. Measurements were quick to perform and were well tolerated by all subjects.

This study aims to compare SBIs, deep white matter lesions (DWMLs), and periventricular white matter lesions (PWMLs) in ipsilateral and contralateral hemispheres to internal carotid artery (ICA) stenosis, and investigate their association with stenosis grade in patients with asymptomatic  ≥ 50% unilateral extracranial ICA stenosis. Patients without previous history of stroke and/or transient ischemic attack who had ≥ 50% stenosis in unilateral ICA on carotid color Doppler ultrasound were enrolled in the study. Patient demographics, vascular risk factors and ICA stenosis grades; number, loc...

DISCUSSION:  VWF:Ag expression, a marker of endothelial ± platelet activation, is enhanced in recently symptomatic versus asymptomatic carotid stenosis patients, including in MES-ve patients, and decreases with ADAMTS13 activity over time following atherosclerotic TIA/ischemic stroke.

Authors: Nezu T, Hosomi N Abstract Carotid ultrasonography is useful for the assessments of the risk stratification for stroke or coronary artery disease, because it is a simple, repeatable, and noninvasive procedure. The carotid intima-media thickness (IMT), which is assessed using carotid ultrasonography, is a widely used surrogate marker for the severity of atherosclerosis. Several large clinical studies showed that increased carotid IMT is associated with the future stroke or cardiovascular events. In addition, in many clinical trials, it has been adopted for surrogate markers of clinical endpoints of medical i...

Ischemic damage after stroke disrupts the complex balance of inhibitory and excitatory activity within cortical network causing brain functional asymmetry. Cerebellar deep nuclei with its extensive projections to cortical regions could be a prospective target for stimulation to restore inter-hemispheric balance and enhance neural plasticity after stroke. In our study, we repeatedly stimulated the lateral cerebellar nucleus (LCN) by low-intensity focused ultrasound (LIFU) for 3 days to enhance rehabilitation after middle cerebral artery occlusion (MCAO) in a mouse stroke model. The neural activity of the mice sensorimotor c...

Authors: Sun Y, Xu L, Jiang Y, Ma M, Wang XY, Xing Y Abstract The stability of carotid artery plaque serves a key role in the occurrence of stroke. The present study was based on the recruitment of patients with acute ischemic cerebrovascular disease. High-resolution magnetic resonance imaging (HR-MRI) was used to identify the nature of carotid artery plaque, and the results were then used to manage the high-risk group of stroke. The patients were divided equally into a symptomatic group (36 cases) and an asymptomatic group (36 cases). According to the degree of carotid artery stenosis, the patients were divided in...

We describe a modified step-wise approach to previously published online article by Pitta et al. from 2017 SCAI communication in the management of catheter entrapment and describe the technique for ultrasound guided brachial plexus block, which helped avoid need for surgical removal.

We report a case of a young woman with a left middle cerebral artery (MCA) ischemic stroke. The patient had history of HIV-1 infection, with periods of therapeutic non-compliance. Initial computed tomography (CT) imaging studies showed stenosis of the M1 segment of the left MCA, and magnetic resonance imaging (MRI) confirmed infarction of the MCA territory. Serial transcranial Doppler ultrasound revealed progressive occlusion of the MCA and stenosis of the left anterior cerebral artery. Systemic investigation for other causes of stroke was normal. Lumbar puncture revealed a mildly inflammatory cerebrospinal fluid, and HSV-...

CONCLUSIONS: Stroke and TIA are common presentation patterns associated with GCA and should be suspected in all CVE-related cases with high acute-phase reactants commonly present in the elderly. This ischemic subgroup exhibited a higher mortality rate. PMID: 32826078 [PubMed - as supplied by publisher]

Cardiac ultrasound parameters and other clinical data of patients with cardiogenic cerebral embolism were collected. The endpoint was one ‐year recurrent ischemic stroke. We found that left atrial enlargement is an independent risk factor for one‐year recurrence of ischemic stroke in patients with cardiogenic cerebral embolism. AbstractBackgroundLeft atrial enlargement (LAE) was reported to be associated with ischemic stroke and its recurrence. Limited data are available on the relationship of LAE and cardiogenic cerebral embolism (CCE). Our aim is to access the association of left atrial size and the recurrence of isc...
