Multi‐modal CT in acute stroke: wait for a serum creatinine before giving intravenous contrast? No!
ConclusionsThe incidence of CIN is low when MMCT is used routinely to assess acute stroke patients. In this population, CIN was a biochemical phenomenon that did not have clinical manifestations, cause chronic kidney disease, require dialysis, or negatively impact on 90‐day mRS outcomes. Renal profiling and waiting for a baseline serum‐creatinine are an unnecessary delay to emergency reperfusion treatment.

Canadian Stroke Best Practice Recommendations: Hyperacute Stroke Care Guidelines, Update 2015
The 2015 update of the Canadian Stroke Best Practice Recommendations Hyperacute Stroke Care guideline highlights key elements involved in the initial assessment, stabilization, and treatment of patients with transient ischemic attack (TIA), ischemic stroke, intracerebral hemorrhage, subarachnoid hemorrhage, and acute venous sinus thrombosis. The most notable change in this 5th edition is the addition of new recommendations for the use of endovascular therapy for patients with acute ischemic stroke and proximal intracranial arterial occlusion. This includes an overview of the infrastructure and resources required ...

Dynamic changes of intramural hematoma in patients with acute spontaneous internal carotid artery dissection
ConclusionsSpatial and temporal dynamics of intramural hematomas after spontaneous internal carotid artery dissection showed an early volume increase with concomitant progression of the internal carotid artery stenosis in 5 of 10 patients. Although spontaneous internal carotid artery dissection overall carries a good prognosis with spontaneous hematoma resorption in all our patients, early follow‐up imaging may be considered, especially in case of new clinical symptoms.

Sparing of the hippocampus indicates better collateral blood flow in acute posterior cerebral artery occlusion
ConclusionsInvolvement of the hippocampus in proximal posterior cerebral artery occlusion is frequently but not obligatorily observed and highly dependent on the extent of collateralization. The same holds true for hippocampal infarction patterns.

The shape of middle cerebral artery and plaque location: high‐resolution MRI finding
ConclusionThe shape of middle cerebral artery may be a factor determining the location of early atherosclerotic plaque.

Prediction of intracerebral haemorrhage expansion with clinical, laboratory, pharmacologic, and noncontrast radiographic variables
ConclusionClinical and noncontrast radiographic variables only weakly predict hematoma expansion. Examination of other indicators, such as computed tomographic angiography contrast extravasation (the ‘spot sign’), may prove more valuable in acute intracerebral haemorrhage care.

Compensatory intracranial arterial dilatation in extracranial carotid atherosclerosis: The Northern Manhattan Study
ConclusionsWe did not find an association of extracranial carotid atherosclerosis with dolichoectasia. However, we found that dolichoectasia is more frequent when intracranial collaterals are available suggesting a compensatory process that needs further investigation.

Oral direct thrombin inhibitor as an alternative in the management of cerebral venous thrombosis: a series of 15 patients
ConclusionsWe report the largest series of cerebral vein thrombosis patients treated with dabigatran. Clinical outcome was excellent in most patients and not different from other studies. Dabigatran could possibly be considered an alternative to warfarin; nevertheless, further prospective assessment with randomized controlled studies is warranted.

Threshold for NIH stroke scale in predicting vessel occlusion and functional outcome after stroke thrombolysis
ConclusionsIdeally, all acute stroke patients should have immediate access to multimodal imaging. In reality these services are limited. Baseline National Institutes of Health Stroke Scale scores of 11 and 12 were identified as markers of baseline vessel occlusion and functional independency after intravenous thrombolysis, respectively. These values are time dependent; therefore, a threshold of National Institutes of Health Stroke Scale 9 or 10 points may be considered in the prehospital selection of patients for immediate transfer to centers with multimodal imaging and availability of highly specialized treatments.

Imaging of occlusive thrombi in acute ischemic stroke
Thrombi, or clots, often occlude proximal segments of the cerebral arterial circulation in acute ischemic stroke. Thromboembolic occlusion or thrombi superimposed on atherosclerotic plaque are the principal focus of acute stroke therapies such as thrombolysis or thrombectomy. We review the imaging characteristics of thrombi on multimodal computed tomography and magnetic resonance imaging, angiography, and ultrasonography, summarizing recent studies that facilitate therapeutic decision‐making from these noninvasive studies. Information about the location, size, and imaging characteristics can be ascertained using these te...

Should minor stroke patients be thrombolyzed? A focused review and future directions
Stroke is a leading cause of morbidity and mortality worldwide. Up to 80% of ischemic stroke patients may initially present with minor symptoms. Minor stroke and transient ischemic attack patients are typically treated conservatively with antiplatelet agents and general vascular prevention strategies. Yet a high proportion develop recurrent stroke or progression of stroke and up to one in four of these patients are disabled or dead at follow‐up. Minor or rapidly improving symptoms are the top reasons for withholding thrombolytic therapy to time‐eligible stroke patients as they are believed to be ‘too good to treat’...

Canadian Stroke Best Practice Recommendations: secondary prevention of stroke guidelines, update 2014
Every year, approximately 62 000 people with stroke and transient ischemic attack are treated in Canadian hospitals. The 2014 update of the Canadian Secondary Prevention of Stroke guideline is a comprehensive summary of current evidence‐based recommendations for clinicians in a range of settings, who provide care to patients following stroke. Notable changes in this 5th edition include an emphasis on treating the highest risk patients who present within 48 h of symptom onset with transient or persistent motor or speech symptoms, who need to be transported to the closest emergency department with capacity for advanced...

Factors affecting clinical outcome in large‐vessel occlusive ischemic strokes
Clinical outcome after large‐vessel occlusive strokes depends on admitting clinical condition, successful recanalization, and robust collateral circulation. However, predicting successful recanalization and quantifying collateral status in the acute setting remain elusive. Successful recanalization has many predictive factors. Strong evidence supports increasing clot length being associated with poor recanalization. Current imaging techniques completed in the acute setting suggest that clot length can be estimated with a clot burden score. In vitro evidence suggests that clots with more red blood cells and less thrombin ...
