Does b1000-b0 Mismatch Challenge Diffusion-Weighted Imaging-Fluid Attenuated Inversion Recovery Mismatch in Stroke? Brief Reports
Conclusions— b1000–b0 mismatch may identify patients with ischemic stroke of the within 4.5 hours of onset with high positive predictive value, perhaps constituting an alternative imaging tissue clock.

Thrombolysis in Ischemic Stroke Without Arterial Occlusion at Presentation Clinical Sciences
Conclusions— This study provides crucial data that patients with ischemic stroke who do not have visible arterial occlusion at presentation may benefit from thrombolysis.

Good Outcome Rate of 35% in IV-tPA-Treated Patients With Computed Tomography Angiography Confirmed Severe Anterior Circulation Occlusive Stroke Clinical Sciences
Conclusions— IV-tPA treatment resulted in significantly better outcomes in patients with severely symptomatic stroke with major anterior circulation occlusions. The 35% good outcome rate was similar to rates found in endovascular therapy trials. Vascular imaging may help in patient selection and stratification for trials of IV-thrombolytic and endovascular therapies.

Smoking-Thrombolysis Paradox: Recanalization and Reperfusion Rates After Intravenous Tissue Plasminogen Activator in Smokers With Ischemic Stroke Original Contributions
Conclusions— Smoking is independently associated with recanalization and reperfusion, indicating that thrombolytic therapy acts more effectively in smokers; because of small numbers, these results should be considered preliminary. Clinical Trial Registration— URL: http://clinicaltrials.gov. Unique Identifier: NCT00715533.

Clot Length Distribution and Predictors in Anterior Circulation Stroke: Implications for Intra-Arterial Therapy Brief Reports
Conclusions— The majority of anterior circulation proximal occlusions are ≥8 mm long, helping to explain the low published rates of intravenous tissue-type plasminogen activator recanalization. Internal carotid artery-terminus occlusion is an excellent marker for clot length ≥8 mm; vessel-imaging status alone may be sufficient. Thin-section noncontrast computed tomography seems useful for patients with middle cerebral artery occlusion because of the wide variability of clot lengths.

Vessel Wall Magnetic Resonance Imaging in Acute Ischemic Stroke: Effects of Embolism and Mechanical Thrombectomy on the Arterial Wall Clinical Sciences
Conclusions— Mechanical thrombectomy results in intracranial arterial wall thickening and enhancement, potentially mimicking the VW-MRI appearance of primary arteritis. This arterial wall abnormality is less common in patients with arterial occlusion who have been treated with medical therapy alone.

Erythrocyte Fraction Within Retrieved Thrombi Contributes to Thrombolytic Response in Acute Ischemic Stroke Clinical Sciences
Conclusions—In EVT-attempted patients with acute ischemic stroke, IVT responsiveness would be closely associated with RBC fraction.

Younger Stroke Patients With Large Pretreatment Diffusion-Weighted Imaging Lesions May Benefit From Endovascular Treatment Clinical Sciences
Conclusions— There was a growing risk for poor outcome and symptomatic intracerebral hemorrhage with increasing pretreatment DWI lesion volumes. Nevertheless, favorable outcome was achieved in every third patient with DWI lesions >70 mL after successful endovascular reperfusion, whereas after poor or failed reperfusion, outcome was favorable in only every 12th patient. Therefore, endovascular treatment might be considered in patients with large DWI lesions, especially in younger patients.

Identification of Reversible Disruption of the Human Blood-Brain Barrier Following Acute Ischemia Brief Reports
Conclusions— This study demonstrates that diffuse, mild BBB disruption in the acutely ischemic human brain is reversible with reperfusion. This study also confirms prior findings that focal severe BBB disruption confers an increased risk of hemorrhagic transformation in patients treated with intravenous tissue-type plasminogen activator.

Worse stroke outcome in atrial fibrillation is explained by more severe hypoperfusion, infarct growth, and hemorrhagic transformation
ConclusionAtrial fibrillation is associated with greater volumes of more severe baseline hypoperfusion, leading to higher infarct growth, more frequent severe hemorrhagic transformation and worse stroke outcomes.

Thrombolytic Therapy Is an Only Determinant Factor for Stroke Evolution in Large Anterior Choroidal Artery Infarcts
Conclusions: Thrombolytic therapy is an only determinant factor for stroke evolution in large AChA infarcts, which reduced the risk of stroke evolution and improved functional outcome.

Safety and Effectiveness of Endovascular Treatment after 6 Hours of Symptom Onset in Patients with Anterior Circulation Ischemic Stroke: A Matched Case Control Study
Conclusions: We did not observe any evidence of benefit in halting neurologic worsening or improving outcomes among patients undergoing endovascular treatment for treatment of an anterior circulation ischemic stroke after 6 hours of symptom onset. Strong evidence of both the safety and efficacy of emergent endovascular treatment when administered to patients with stroke in the anterior circulation is needed.
