Platelet rich clots are resistant to lysis by thrombolytic therapy in a rat model of embolic stroke
Conclusions Site specific delivery of platelet rich clots to the MCA origin resulted in high rates of MCA occlusion, low rates of spontaneous clot lysis and large infarction. These platelet rich clots were highly resistant to tPA with or without microbubble-enhanced sonothrombolysis. This resistance of platelet rich clots to enhanced thrombolysis may explain recanalization failures clinically and should be an impetus to better clot-type identification and alternative recanalization methods.

Validity of Shape as a Predictive Biomarker of Final Infarct Volume in Acute Ischemic Stroke Clinical Sciences
Conclusions— Our findings suggest that lesion shape contains important predictive information and reflects important environmental factors that might determine the progression of ischemia from the core.

Residual Risk of Stroke and Death in Anticoagulated Patients According to the Type of Atrial Fibrillation: AMADEUS Trial Clinical Sciences
Conclusions— The risk of cardiovascular death, stroke, or systemic embolism is higher in anticoagulated patients with permanent AF than in those with nonpermanent AF, regardless of preexisting heart failure.

Accuracy of First Recorded “Last Known Normal” Times of Stroke Code Patients
This study investigates whether a difference exists between preliminary LKN times (first responders and emergency department practitioners) and revised LKN times (neurology/stroke practitioners), and what potential impact on emergent management of acute stroke this discrepancy may pose.

Migraine makes the stroke grow faster?
Long associated with increased incidence of stroke,1,2 migraine has been linked with mechanisms involving the vasculature (vasospasm, arterial dissection, endothelial dysfunction, venous thrombosis), heart (patent foramen ovale), and blood (hypercoagulability).3 Since cerebral ischemia can induce cortical spreading depression, the physiologic process underlying aura, migraine with aura may theoretically represent a TIA equivalent in a subset of people. In addition to the heightened occurrence of stroke in migraineurs, a growing body of evidence suggests more dire consequences when stroke occurs, with experiments in mice wi...

Post-IV thrombolytic headache and hemorrhagic transformation risk in acute ischemic stroke
Conclusion: tPA-associated headache does not predict increased risk of HT and has no other prognostic importance in patients with AIS. Prospective studies with a larger cohort may be needed to further explore this relationship.

Prothrombotic State in Patients With a Left Atrial Appendage Thrombus of Unknown Origin and Cerebrovascular Events Clinical Sciences
Conclusions— Prothrombotic blood alterations could be involved in the LAA thrombus formation in patients without documented atrial fibrillation and are associated with increased risk of stroke or transient ischemic attack during follow-up.

Renal Function and the Risk of Stroke and Bleeding in Patients With Atrial Fibrillation Clinical Sciences
Background and Purpose—We sought to determine the risk of stroke/thromboembolism and bleeding associated with reduced renal function in patients with atrial fibrillation and the risk of stroke and bleeding associated with warfarin treatment in specific estimated glomerular filtration rate (eGFR) groups.Methods—We conducted a register-based cohort study and included patients discharged with nonvalvular atrial fibrillation from 1997 to 2011 with available eGFR.Results—A total of 17 349 patients were identified with eGFR available at baseline. All levels of lower eGFR were associated with higher risk of stroke/thrombo...

Infarct Pattern and Collateral Status in Adult Moyamoya Disease Clinical Sciences
Conclusions—In the studied population of adult MMD patients, embolic phenomenon played an important role in ischemic stroke. Therapeutic strategies against thromboembolism, as well as collateral enhancing strategies targeting improvement of hemodynamic status or increased washout of emboli, are warranted.

Is Unexplained Early Neurological Deterioration After Intravenous Thrombolysis Associated With Thrombus Extension? Clinical Sciences
Conclusions—In this study, unexplained END occurring after thrombolysis was independently associated with susceptibility vessel sign extension, suggesting in situ thrombus extension or re-embolization. These findings strengthen the need to further investigate early post-thrombolysis administration of antithrombotics to reduce the risk of this ominous clinical event.
