Results of percutaneous closure of patent foramen ovale with the GORE® septal occluder
ConclusionPFO closure with the GSO is accompanied by a high technical success rate and closure rates similar to other currently used devices. The incidence of AF was higher than reported with most other devices. This may be a chance finding but warrants further investigation in larger trials. © 2013 Wiley Periodicals, Inc.

Conclusion. PFO closure with the GSO is accompanied by a high technical success rate and closure rates similar to other currently used devices. The incidence of atrial fibrillation was higher than reported with most other devices. This may be a chance finding but warrants further investigation in larger trials. © 2013 Wiley Periodicals, Inc.

Clot composition and treatment approach to acute ischemic stroke: The road so far
We present a review of recent studies on the histopathologic analysis of thrombi, studies of MRI, and CT imaging correlation with thrombus histology, and detailed structural analysis of thromboemboli retrieved by thrombectomy devices during an acute ischemic stroke.

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.

Translational perspectives on perfusion–diffusion mismatch in ischemic stroke
Magnetic resonance imaging has tremendous potential to illuminate ischemic stroke pathophysiology and guide rational treatment decisions. Clinical applications to date have been largely limited to trials. However, recent analyses of the major clinical studies have led to refinements in selection criteria and improved understanding of the potential implications for the risk vs. benefit of thrombolytic therapy. In parallel, preclinical studies have provided complementary information on the evolution of stroke that is difficult to obtain in humans due to the requirement for continuous or repeated imaging and pathological veri...

Ischemic Stroke in Evolution: Predictive Value of Perfusion Computed Tomography
Background: Various perfusion computed tomography (PCT) parameters have been used to identify tissue at risk of infarction in the setting of acute stroke. The purpose of this study was to examine predictive value of the PCT parameters commonly used in clinical practice to define ischemic penumbra. The patient selection criterion aimed to exclude the effect of thrombolysis from the imaging data.Methods: Consecutive acute stroke patients were screened and a total of 18 patients who initially underwent PCT and CT angiogram (CTA) on presentation but did not qualify to receive thrombolytic therapy were selected. The PCT images ...

Thrombus Aspiration in ThrOmbus containing culpRiT lesions in Non-ST-Elevation Myocardial Infarction (TATORT-NSTEMI): study protocol for a randomized controlled trial
Background: Current guidelines recommend thrombus aspiration in patients with ST-elevation myocardial infarction (STEMI); however, there are insufficient data to unequivocally support thrombectomy in patients with non-STEMI (NSTEMI). Methods: The TATORT-NSTEMI (Thrombus Aspiration in ThrOmbus containing culpRiT lesions in Non-ST-Elevation Myocardial Infarction) trial is a prospective, controlled, multicenter, randomized, open-label trial enrolling 460 patients. The hypothesis is that, against a background of early revascularization, adjunctive thrombectomy leads to less microvascular obstruction (MO) compared with conventi...

Evaluation of plasma d‐dimer plus fibrinogen in predicting acute CVST
Conclusionsd‐dimer may serve as an important screening tool to determine the urgency of obtaining magnetic resonance imaging/magnetic resonance venography or digital subtraction angiography in patients presenting with clinical symptoms that are suspected of cerebral venous sinus thrombosis. Furthermore, d‐dimer in combination with fibrinogen may increase the predictive value of acute cerebral venous sinus thrombosis.

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.

Regulatory T cells are strong promoters of acute ischemic stroke in mice by inducing dysfunction of the cerebral microvasculature
We have recently identified T cells as important mediators of ischemic brain damage, but the contribution of the different T-cell subsets is unclear. Forkhead box P3 (FoxP3)–positive regulatory T cells (Tregs) are generally regarded as prototypic anti-inflammatory cells that maintain immune tolerance and counteract tissue damage in a variety of immune-mediated disorders. In the present study, we examined the role of Tregs after experimental brain ischemia/reperfusion injury. Selective depletion of Tregs in the DEREG mouse model dramatically reduced infarct size and improved neurologic function 24 hours after stroke a...

Thrombosis of a Developmental Venous Anomaly in Inflammatory Bowel Disease: Case Report and Radiologic Follow-up
We describe the clinical and neuroradiologic follow-up of a 62-year-old man with a history of inflammatory bowel disease (IBD) presenting with new onset epilepsy and intracranial hemorrhage caused by thrombosis of a DVA who fully recovered after treatment with oral anticoagulant therapy. Patients with IBD have an increased risk of thrombosis because of inflammatory activity and the hypercoagulable state. Here we describe the first case of DVA thrombosis in a patient with IBD, and we show clinical and neuroradiologic follow-up after anticoagulant therapy.

Psychiatric remission with warfarin: Should psychosis be addressed as plasminogen activator imbalance?
Conclusion: Our findings suggest that normalization of plasminogen activator levels in the brain may induce long-term remission of psychotic symptoms. Randomized controlled studies may help clarify the role of anticoagulation in the treatment of psychosis.

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.
