Protocol for the perfusion and angiography imaging sub‐study of the Third International Stroke Trial (IST‐3) of alteplase treatment within six‐hours of acute ischemic stroke
RationaleIntravenous thrombolysis with recombinant tissue Plasminogen Activator improves outcomes in patients treated early after stroke but at the risk of causing intracranial hemorrhage. Restricting recombinant tissue Plasminogen Activator use to patients with evidence of still salvageable tissue, or with definite arterial occlusion, might help reduce risk, increase benefit and identify patients for treatment at late time windows. AimsTo determine if perfusion or angiographic imaging with computed tomography or magnetic resonance help identify patients who are more likely to benefit from recombinant tissue Plasminogen Ac...

Correlation of imaging and histopathology of thrombi in acute ischemic stroke with etiology and outcome: a systematic review
Conclusions The hyperdense artery sign is associated with RBC-rich thrombi and improved recanalization rates. However, there was no association between the histopathological characteristics of thrombi and stroke etiology and angiographic outcomes.

Initial Experience with Upfront Arterial and Perfusion Imaging among Ischemic Stroke Patients Presenting within the 4.5-hour Time Window
Conclusions: An upfront CTA/CTP protocol aided stroke team decision-making in nearly half of cases. Implementation of a CTA/CTP protocol was associated with a learning curve of 6 months before door to needle time ≤60 minutes returned to similar rates as the pre-CTA/CTP protocol.

Overcoming the evening/weekend effects on time delays and outcomes of endovascular stroke therapy: the Calgary Stroke Program experience
Conclusions Some delays were encountered during evenings and weekend hours. Despite that, it was feasible to achieve a relatively short imaging to reperfusion times during these hours, in comparison to existing literature. A target universal time metric is needed to assess the timeliness of endovascular therapy in stroke centers.

CT Angiogram Helps to Predict Ischemic Stroke in Dizzy Patients, but NOT Better than the Clinical Examination (P3.084)
Conclusions: In patients with subjective dizziness, stroke risk factors and focal exam findings predict acute ischemic stroke. Calcification on CTA is also predictive, but does not significantly improve sensitivity.Disclosure: Dr. Chen has nothing to disclose. Dr. Schneider has nothing to disclose. Dr. Marsh has nothing to disclose.

Role of atherosclerosis, clot extent, and penumbra volume in headache during ischemic stroke
Conclusions: Headache in the early phase of ischemic stroke tends to occur less often in patients with atherosclerosis than in patients without atherosclerosis in the large cerebral arteries. This finding lends support to the hypothesis that vessel wall elasticity is a necessary contributing factor in the occurrence of headache during acute ischemic stroke.

Association of multiple infarctions and ICAS with outcomes of minor stroke and TIA
Conclusions: The presence of multiple infarctions and ICAS were both associated with an increased risk of 90-day ischemic stroke in patients with minor stroke or TIA, while the presence of both imaging features had a combined effect. ClinicalTrials.gov identifier: NCT00979589.

Endovascular treatment beyond 24 hours from the onset of acute ischemic stroke: the Italian Registry of Endovascular Thrombectomy in Acute Stroke (IRETAS)
Conclusions These findings suggest that, in a real world setting, very late endovascular therapy is feasible in appropriately selected patients.

Evaluation of direct-to-angiography suite (DTAS) and conventional clinical pathways in stroke care: a simulation study
Conclusions The results of the SimStroke model showed comparable time intervals for door-to-reperfusion for DTAS compared with a conventional stroke care pathway. However, the DTAS pathway was very sensitive to baseline angiography suite utilization, with even a 10% increase eliminating the advantages of DTAS compared with the conventional pathway. Given the minimal time savings modeled here, further investigation of implementing the DTAS pathway in clinical care is warranted.

The Utility of Middle Cerebral Artery Clot Density and Burden Assessment by Noncontrast Computed Tomography in Acute Ischemic Stroke Patients Treated with Thrombolysis
Conclusions: Utility of the HMCAS as a prognostic marker in stroke thrombolysis is not high in the CT angiography era. Previous observation regarding its positive prognostic role can be attributed to its association with proximal location and extent of clot burden, which are detectable reliably with current CT angiography techniques. Neither quantification nor extent of increased density seems to have clinical utility for treatment decision making in MCA strokes and prediction of emboli composition and response to recanalization attempt.

The Impact of Comprehensive Stroke Care Capacity on the Hospital Volume of Stroke Interventions: A Nationwide Study in Japan: J-ASPECT Study
We examined the effect of hospital characteristics, having a t-PA protocol, and the number of fulfilled CSC items (total CSC score) on the hospital volume of t-PA infusion, removal of intracerebral hemorrhage, and coiling and clipping of intracranial aneurysms performed in 2009.Results: Approximately 55% of hospitals responded to the survey. Facilities with t-PA protocols (85%) had a significantly higher likelihood of having 23 CSC items, for example, personnel (eg, neurosurgeons: 97.3% versus 66.1% and neurologists: 51.3% versus 27.7%), diagnostic (eg, digital cerebral angiography: 87.4% versus 43.2%), specific expertise...

Outcomes in patients with acute ischemic stroke from proximal intracranial vessel occlusion and NIHSS score below 8
Conclusions Patients with acute stroke due to large vessel occlusion and low admission NIHSS scores (0–7 range) may have poor functional outcomes at discharge. These patients, if not eligible for IV thrombolysis, might benefit from IA revascularization therapies.

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...

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’...
