Carotid web: an under-recognized and misdiagnosed ischemic stroke etiology
Conclusion CaW was predominantly identified in patients with strokes/TIAs rather than asymptomatic patients. CaW was commonly overlooked in facilities with lower levels of cerebrovascular certification. Recognition of CaW at a CSC has significantly increased over time, independent of overall imaging and stroke patient volume.

Intracranial Steno-Occlusive Arterial Disease and its Associations in Egyptian Ischemic Stroke Patients Brief Report
Conclusion— Symptomatic and asymptomatic intracranial arterial steno-occlusive disease was prevalent in this Egyptian acute stroke sample. This might have important implications on stroke management in this population.

Interaction of age with the ischaemic penumbra, leptomeningeal collateral circulation and haemodynamic variables in acute stroke: a pilot study
Conclusions These findings, described for the first time in a clinical cohort using whole brain CT perfusion and concomitant vascular imaging, suggest that age has a differential effect on acute tissue compartments in the wake of a preserved collateral vascular response and haemodynamic parameters. In agreement with the preclinical literature, the results point to a distinct tissue response to acute ischaemia in the ageing brain and merit validation studies in larger cohorts, particularly in relation to clinical outcomes.

Length of carotid stenosis predicts peri‐procedural stroke or death and restenosis in patients randomized to endovascular treatment or endarterectomy
ConclusionsIncreasing stenosis length is an independent risk factor for peri‐procedural stroke or death in endovascular treatment and carotid endarterectomy, without favoring one treatment over the other. However, the excess restenosis rate after endovascular treatment compared with carotid endarterectomy increases with longer stenosis at baseline. Stenosis length merits further investigation in carotid revascularisation trials.

Incidence of Venous Thromboembolism in the Wake of the Clots in Legs Or sTockings after Stroke (CLOTS) Study Brief Reports
Conclusions— Discontinuation of compressive stockings did not increase venous thromboembolism incidence. There was a trend toward more deep vein thrombosis and fewer PEs after CLOTS, which might be because of increased clinical vigilance in the diagnosis of deep vein thrombosis, but a chance variation cannot be excluded.

Large ct perfusion-defined mismatch predicts early improvement after iv thrombolysis in acute ischaemic stroke
Conclusions Acute CTP mismatch ratio predicted early neurological improvement after IV rtPA treatment, with large mismatch ratios yielding better prediction of favourable early response. The combination of NIHSS and CTP mismatch may improve prediction of poor outcome. Since all patients received rtPA, no conclusion can be made about the interaction between imaging variables and rtPA.

The halifax acute stroke imaging study (hasis): does ct perfusion scanning in acute ischemic stroke predict final infarct volume?
Conclusions Results from HASIS suggest information from admission CTP and SI in suspected AIS patients can predict final infarct volume, where final volume of infarcted brain will not be smaller than that predicted by CTP CBV or CTA SI.

Alberta Stroke Program Early Computed Tomography Score to Select Patients for Endovascular Treatment: Interventional Management of Stroke (IMS)-III Trial Clinical Sciences
Conclusions— ASPECTS is a strong predictor of outcome and a predictor of reperfusion. ASPECTS did not identify a subpopulation of subjects that particularly benefitted from endovascular therapy immediately after routine intravenous tPA.

Association Between Arterial Calcifications and Nonlacunar and Lacunar Ischemic Strokes Clinical Sciences
Conclusions— The only difference we found between nonlacunar and lacunar strokes was a higher calcification volume in the aortic arch in nonlacunar strokes. Our findings only partially confirm the notion of distinct etiologies and suggest that the potential role of other plaque components, plaque morphology, and aortic arch calcifications in ischemic stroke subtypes awaits further evaluation.

Evaluating Middle Cerebral Artery Atherosclerotic Lesions in Acute Ischemic Stroke Using Magnetic Resonance T1-weighted 3-Dimensional Vessel Wall Imaging
Background: Atherosclerotic lesions in intracranial arteries are a leading cause of ischemic stroke. Magnetic resonance angiography (MRA) is often used to assess atherosclerotic changes by detecting luminal narrowing, whereas it cannot directly visualize atherosclerotic lesions. Here, we used a 3-dimensional vessel wall imaging (3D-VWI) technique to evaluate intracranial arterial wall changes in acute stroke.Methods: Eighteen consecutive patients with acute noncardioembolic stroke in the middle cerebral artery (MCA) territory who were prospectively examined with a 1.5-T magnetic resonance scanner were studied. T1-weighted ...

Factors Associated with Proximal Carotid Axis Occlusion in Patients with Acute Stroke and Atrial Fibrillation
Conclusions: Female sex, advanced age, history of systemic embolism, and higher BNP level were independently associated with more proximal carotid axis occlusion. Patients with AF having these factors may be prone to have relatively large thrombi in the heart.
