Pulmonary Embolism in Ischemic Stroke: Clinical Presentation, Risk Factors, and Outcome Stroke
Conclusions In this large cohort study, PE occurred in nearly 1% of AIS patients. PE was more common in patients with severe stroke, history of cancer, previous DVT/PE or acute DVT and associated with lower short- and long-term survival, greater disability, and longer length of stay.

Ischemic Stroke Clinical Sciences
Conclusions—Histological thrombus features vary significantly according to the underlying cause and may help to differentiate between cardioembolic and noncardioembolic stroke. In addition, our study supports the hypothesis that most cryptogenic strokes have a cardioembolic cause.

Carotid-Bulb Atypical Fibromuscular Dysplasia in Young Afro-Caribbean Patients With Stroke Brief Reports
Conclusions— CaFMD could be a common condition in young Afro-Caribbeans with carotid-territory ischemic stroke. Recurrences were frequent under antiplatelet treatment, while surgical CaFMD removal seemed more effective.

Influence of Arterial Occlusion on Outcome After Intravenous Thrombolysis for Acute Ischemic Stroke Clinical Sciences
Conclusions— In this retrospective analysis of consecutive patients with acute ischemic stroke, there was a trend for more favorable outcomes with IVT in the setting of initial arterial occlusion than in the setting of no/minimal obstruction. Before confirmation in randomized controlled studies, this information should not influence thrombolysis decisions, however.

Permeable Thrombi Are Associated With Higher Intravenous Recombinant Tissue-Type Plasminogen Activator Treatment Success in Patients With Acute Ischemic Stroke Clinical Sciences
Conclusions— Thrombus perviousness, as measured on computed tomography in the acute stage of ischemic stroke, is strongly associated with recanalization after intravenous r-tPA treatment and with favorable functional outcome.

Thrombus Permeability Is Associated With Improved Functional Outcome and Recanalization in Patients With Ischemic Stroke Clinical Sciences
Conclusions— This study shows that simultaneous measurement of thrombus attenuation in noncontrast computed tomography and computed tomographic angiography allows for quantification of thrombus perviousness. Thrombus perviousness is strongly associated with improved functional outcome, smaller final infarct volume, and higher recanalization rate.

Associations Between Collateral Status and Thrombus Characteristics and Their Impact in Anterior Circulation Stroke Clinical Sciences
Conclusions—Patients with lower thrombus burden and higher thrombus perviousness scores had higher collateral score. The positive effect of thrombus perviousness on clinical outcome was only present in patients with moderate and high collateral scores.Clinical Trial Registration—URL: http://www.trialregister.nl.

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.

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’...

Sensitivity and Specificity of the Hyperdense Artery Sign for Arterial Obstruction in Acute Ischemic Stroke Clinical Sciences
Conclusions— When present in acute ischemic stroke, HAS indicates a high likelihood of arterial obstruction, but its absence indicates only a 50/50 chance of normal arterial patency. Thin-slice CT improves sensitivity of HAS detection. Clinical Trial Registration— URL: http://www.controlled-trials.com/ISRCTN25765518. Unique identifier: ISRCTN25765518.

Distance to Thrombus in Acute Middle Cerebral Artery Occlusion: A Predictor of Outcome After Intravenous Thrombolysis for Acute Ischemic Stroke Clinical Sciences
Conclusion— DT is an independent predictor of clinical outcome in patients with acute MCA occlusion treated with IVT. In acute stroke with MCA occlusion confirmed by CT angiography and DT <16 mm, the likelihood of a good clinical outcome after treatment with IVT was exponentially <50%. This might warrant the evaluation of other therapy forms than IVT in patients with proximal MCA occlusion.

Incidence of Venous Thromboembolism in the Wake of the Clots in Legs Or sTockings after Stroke (CLOTS) Study Brief Reports
Conclusions— Discontinuation of compressive stockings did not increase venous thromboembolism incidence. There was a trend toward more deep vein thrombosis and fewer PEs after CLOTS, which might be because of increased clinical vigilance in the diagnosis of deep vein thrombosis, but a chance variation cannot be excluded.
