Capillary Index Score in the Interventional Management of Stroke Trials I and II Clinical Sciences
Conclusions— A f CIS was found in 50% of subjects and was a virtual prerequisite for good outcome in this study subgroup of IMS I and II. We call this the 50% barrier.

Time to Angiographic Reperfusion in Acute Ischemic Stroke: Decision Analysis Clinical Sciences
Conclusions— In our post hoc model with its underlying limitations, endovascular therapy after intravenous r-tPA is the preferred treatment as compared with intravenous r-tPA alone. However, if time to reperfusion exceeds 347 minutes, intravenous r-tPA alone is the recommended strategy. This warrants validation in a randomized, prospective trial among patients with large vessel occlusions.

Residual High-Grade Stenosis After Recanalization of Extracranial Carotid Occlusion in Acute Ischemic Stroke Clinical Sciences
Conclusions— A residual high-grade stenosis of the extracranial ICA occurs in 1 of 6 patients with a symptomatic occlusion in the acute stage of cerebral ischemia. Because this may have implications for secondary prevention, we recommend follow-up imaging in these patients within a week after the event. Clinical Trial Registration— URL: http://www.clinicaltrials.gov. Unique identifier: NCT00880113.

Association Between CT Angiogram Collaterals and CT Perfusion in the Interventional Management of Stroke III Trial Brief Reports
Conclusion— Better collaterals were associated with smaller ischemic core and higher mismatch in the IMS III trial. Collateral assessment and perfusion imaging identify the same biological construct about ischemic tissue sustenance.

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.

Prospective Study Of Acute Ischemic Stroke Sub-Types In A Teritiary Care Hospital In South India (P4.283)
Conclusion: The study contributes to understanding of demographic characteristics, risk factors and stroke-subtype in acute ischemic stroke. Like other studies LVA is the commonest subtype and intra-cranial vessels are commonly involved as in other Asian studies.Disclosure: Dr. Garuda has nothing to disclose.

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 ...

Magnetic Resonance Angiography Detection of Abnormal Carotid Artery Plaque in Patients With Cryptogenic Stroke Stroke
Conclusions Our findings suggest that a proportion of strokes classified as cryptogenic may be mechanistically related to complicated, nonhemodynamically significant cervical carotid artery plaque that can easily be detected by routine magnetic resonance imaging/magnetic resonance angiography acute stroke protocols.

Nonstenotic carotid plaque on CT angiography in patients with cryptogenic stroke
Conclusions: Large but nonstenotic carotid artery plaque is considerably more common ipsilateral than contralateral to cryptogenic stroke, suggesting that nonstenotic plaque is an underrecognized cause of stroke. We measured plaque size using CT angiography, a method that could be easily implemented in clinical practice.

Consensus Statements by Korean Society of Interventional Neuroradiology and Korean Stroke Society: Hyperacute Endovascular Treatment Workflow to Reduce Door-to-Reperfusion Time.
Abstract Recent clinical trials demonstrated the clinical benefit of endovascular treatment (EVT) in patients with acute ischemic stroke due to large vessel occlusion. These trials confirmed that good outcome after EVT depends on the time interval from symptom onset to reperfusion and that in-hospital delay leads to poor clinical outcome. However, there has been no universally accepted in-hospital workflow and performance benchmark for rapid reperfusion. Additionally, wide variety in workflow for EVT is present between each stroke centers. In this consensus statement, Korean Society of Interventional Neuroradiolog...

Stroke Risk After Posterior Circulation Stroke/Transient Ischemic Attack and its Relationship to Site of Vertebrobasilar Stenosis: Pooled Data Analysis From Prospective Studies Clinical Sciences
Conclusions— Symptomatic VB stenosis, particularly intracranial stenosis, is a strong independent predictor of stroke recurrence. The high early risk of stroke provides a strong rationale for randomized trials to determine whether stenting can reduce risk.

Prognostic Evaluation Based on Cortical Vein Score Difference in Stroke Clinical Sciences
Conclusions— The Prognostic Evaluation based on Cortical vein score difference In Stroke score, a novel measure of venous enhancement on CT angiography, accurately predicts clinical outcomes. Venous features on computed tomography angiography provide additional characterization of collateral perfusion and prognostication in acute ischemic stroke.
