Incremental predictive value of carotid arterial strain in patients with stroke
AbstractAlthough increased carotid intima-media thickness (IMT) is a well-known risk factor for stroke, carotid IMT alone is not sufficient for risk stratification. The assessment of arterial properties using velocity vector imaging (VVI) represents a new method for quantifying structural changes. We sought to investigate the characteristics and the clinical value of carotid arterial mechanics using VVI in patients with stroke. Fifty male patients (55  ± 5 years) with stroke, 30 healthy age-matched volunteers (54 ± 8 years), and 30 healthy young male volunteers (29 ± 5 years) were evaluated. The peak circ...

Clinical and imaging features associated with intracranial internal carotid artery calcifications in patients with ischemic stroke
Conclusion ICAC burden reflects a continuum of atherosclerotic disease involving carotid arteries together with other craniocervical vascular beds. ICAC is significantly associated with stroke of large vessel or cardioembolic origin. This information might help the clinician in prioritizing etiologic work-up in the acute period.

Possible Morphological Pathomechanisms of Ischemic Stroke in the Posterior Circulation of Patients with Vertebral Artery Hypoplasia
CONCLUSIONIn patients with VAH, the combination of several pathomechanisms of ischemic stroke and the contribution of several risk factors can cause the clinical manifestation of PCS.

Assessment of Intracranial Collaterals on CT Angiography in Anterior Circulation Acute Ischemic Stroke FELLOWS' JOURNAL CLUB
CONCLUSIONS: Only the Miteff scoring system for intracranial collaterals is reliable for predicting favorable outcome in thrombolyzed acute anterior circulation ischemic stroke. However, poor outcomes can be predicted by most of the existing methods of scoring intracranial collaterals.

Ischemic Stroke: Measurement of Intracranial Artery Calcifications Can Improve Prediction of Asymptomatic Coronary Artery Disease Neuroradiology
Conclusion: The IAC scores quantified by using unenhanced CT correlate significantly with coronary calcium scores and may serve as an independent predictor of asymptomatic CAD in patients with ischemic stroke. © RSNA, 2013

Middle Cerebral Artery Stenosis in Patients with Acute Ischemic Stroke and TIA in Israel BRAIN
CONCLUSIONS: An independent and significant correlation was found between MCA stenosis and vascular risk factors (diabetes mellitus) and vascular diseases, thus emphasizing the similarity of intracranial MCA stenosis and other vascular diseases originating from atherosclerosis. There was no influence of ethnicity on intracranial stenosis in our population.

Visualization of Lenticulostriate Arteries by Flow-Sensitive Black-Blood MR Angiography on a 1.5T MRI System: A Comparative Study between Subjects with and without Stroke BRAIN
CONCLUSIONS: Using FSBB-MRA to visualize LSA branches, we found a significant reduction in the numbers of LSA branches in patients with stroke, and hypertension was inversely related to total LSA length. FSBB is a promising method to investigate the LSA by using 1.5T MR imaging.

Thrombus composition in acute ischemic stroke: A histopathological study of thrombus extracted by endovascular retrieval
Conclusion HAS was significantly associated with early phase thrombus composition. This may enable the prediction of thrombus composition and allow for targeted selection of therapeutic modality.

Middle Cerebral Artery Pulsatility Index is Associated with Cognitive Impairment in Lacunar Stroke
CONCLUSIONSPI was associated with the cognitive performance in patients with lacunar infarcts and a lacunar syndrome. An elevated PI may be related to impairment in several cognitive domains. These findings suggest that transcranial Doppler ultrasonography could be an adjunct tool for early diagnosis of cognitive impairment after stroke.

Impact of Anesthesia on the Outcome of Acute Ischemic Stroke after Endovascular Treatment with the Solitaire Stent Retriever INTERVENTIONAL
CONCLUSIONS: In this single-center study, the anesthetic management during stent retriever thrombectomy with general anesthesia or conscious sedation had no impact on the outcome of patients with large-vessel occlusion in the anterior circulation.

Presence, Characteristics, and Prognostic Associations of Carotid Plaque Among People Living With HIV Peripheral Arterial Disease
Conclusions— There is an increase in incidental carotid plaque, noncalcified plaque, and high-risk plaque among PLWHIV, and the presence and characteristics of carotid plaque are associated with subsequent vascular events.

A Critical Assessment of the Golden Hour and the Impact of Procedural Timing in Stroke Thrombectomy INTERVENTIONAL
CONCLUSIONS: Thrombectomy procedural times beyond 60 minutes are associated with lower revascularization rates and worse 90-day outcomes. Procedural time itself was not an independent predictor of outcome. While stroke thrombectomy procedures should be performed rapidly, our study emphasizes the significance of achieving revascularization despite the requisite procedural time. However, the potential for revascularization must be weighed against the risks associated with multiple thrombectomy attempts.
