Ultrasound and magnetic resonance findings and correlation in hemiplegic patients with shoulder pain.
Conclusion: Although US is recommended as the first method in determining shoulder pathologies in hemiplegic patients, we suggest that MRI should be used as the first choice in hemiplegic patients with shoulder pain. MRI and US findings were not consistent, and US is dependent on the experience of the operator. MRI should be the first choice in cases where the diagnosis will affect the treatment choice due to the lack of correlation between US and MRI findings. PMID: 24722039 [PubMed - in process]

Stiffness Parameter β of Cardioembolism Measured by Carotid Ultrasound Was Lower Than Other Stroke Subtypes
Background: We estimated the stiffness parameter β (β value), which is useful in the assessment of premature atherosclerosis, among patients with different subtypes of cerebral infarction (CI; eg, small-vessel occlusion, large-artery atherosclerosis, cardioembolism, and other determined and undetermined etiologies) to determine the clinical utility of the β value in classification of stroke patients into CI subtypes.Methods: Carotid ultrasonography (ALOKA ProSound SSD-alpha10) was performed in 31 CI patients and 38 control subjects, and the β value of the bilateral common carotid artery at 2.0 cm proximal to the bifur...

Thrombolytic Recanalization of Carotid Arteries Is Highly Dependent on Degree of Stenosis, Despite Sonothrombolysis Stroke
Conclusions In this model, the degree of carotid stenosis had a large effect on thrombolytic recanalization. Sonothrombolysis using standard parameters for intracranial sonothrombolysis did not increase recanalization. Further testing is warranted. The degree of underlying stenosis may be an important predictor of thrombolytic recanalization, and clinical correlation of these findings may provide new approaches to treatment selection for patients with carotid occlusion.

Validation of Noninvasive In Vivo Compound Ultrasound Strain Imaging Using Histologic Plaque Vulnerability Features Clinical Sciences
This study aims at in vivo validation of compound ultrasound strain imaging in patients by relating the measured strains to typical features of vulnerable plaques derived from histology after carotid endarterectomy.Materials and Methods—Strains were measured in 34 severely stenotic (>70%) carotid arteries at the culprit lesion site within 48 hours before carotid endarterectomy. In all cases, the lumen-wall boundary was identifiable on B-mode ultrasound, and the imaged cross-section did not move out of the imaging plane from systole to diastole. After endarterectomy, the plaques were processed using a validated histology ...

Limb Shaking Transient Ischemic Attacks with Normal Neurovascular Ultrasound may Herald Cardioembolic Stroke: ACase Report
We describe a 74 year-old woman with abrupt left arm jerking and normal urgent computed tomography scan, electroencephalography (EEG) as well as carotid and transcranial ultrasound. Two days later she developed an overt ischemic stroke, with left mesencephalon and left cerebellar hemisphere lesions at brain magnetic resonance imaging and paroxysmal atrial fibrillation at Holter-EKG.

Measuring the Optic Nerve Sheath Diameter with Ultrasound in Acute Middle Cerebral Artery Stroke Patients
Measurement of the optic nerve sheath diameter (ONSD) with ultrasound enables non-invasive and indirect assessment of increased intracranial pressure (ICP). Although most of the studies were employed with traumatic brain injury patients, it's increasingly popular in acute ischemic stroke (AIS) studies.

Response to “Measuring the Optic Nerve Sheath Diameter with Ultrasound in Acute Middle Cerebral Artery Stroke Patients”: For Application to Long-Duration Spaceflight (LDSF)
We thank the authors of the study for their contribution to literature and their insights into the utilisation of optic nerve sheath diameter (ONSD) measurements with regards to therapeutic efficacy of thrombolytic therapy (TT) and identification of complications in populations post-MCA stroke. We would like to introduce the discussion of potential translational benefits of this methodology to the field of long-duration spaceflight (LDSF).

Propensity Score-Matched Analysis of Lesion Patterns in Stroke Patients With Patent Foramen Ovale and Patients With Spontaneous Intracranial Artery Dissection
Conclusion: The present study suggests that lesion patterns observed from DWI of patients with PFO and SIAD might provide clues to the etiology of infarcts. Single lesions (cortical or subcortical) might be a typical feature of PFO associated strokes, while multiple lesions in one vascular territory might be a specific feature of SIAD associated strokes. Introduction Both patent foramen ovale (PFO) and spontaneous intracranial artery dissection (SIAD) are important stroke risk factors, especially in young and middle-aged adults (1–3). About 25% of patients with ischemic stroke are cryptogenic (4), and PFO is ...

What Are the Classifications of Perinatal Stroke?
Discussion Perinatal stroke occurs in about 1:1000 live births and is a “focal vascular injury from the fetal period to 28 days postnatal age.” Perinatal stroke is the most common cause of hemiparetic cerebral palsy and causes other significant morbidity including cognitive deficits, learning disabilities, motor problems, sensory problems including visual and hearing disorders, epilepsy, and behavioral and psychological problems. Family members are also affected because of the potential anxiety and guilt feelings that having a child with a stroke presents, along with the care that may be needed over the child&#...
