Role of Biological Markers for Cerebral Bleeding Risk STRATification in Patients with Atrial Fibrillation on Oral Anticoagulants for Primary or Secondary Prevention of Ischemic Stroke (Strat-AF Study): Study Design and Methodology.
Conclusions: The Strat-AF study may be an essential step towards the exploration of the role of a combined clinical biomarker or multiple biomarker models in predicting stroke risk in AF, and might sustain the incorporation of such new markers in the existing stroke prediction schemes by the demonstration of a greater incremental value in predicting stroke risk and improvement in clinical outcomes in a cost-effective fashion.

Pathophysiologic mechanisms, neuroimaging and treatment in wake-up stroke.
Abstract Wake-up stroke (WUS) or ischemic stroke occurring during sleep accounts for 14%-29.6% of all ischemic strokes. Management of WUS is complicated by its narrow therapeutic time window and attributable risk factors, which can affect the safety and efficacy of administering intravenous (IV) tissue plasminogen activator (t-PA). This manuscript will review risk factors of WUS, with a focus on obstructive sleep apnea, potential mechanisms of WUS, and evaluate studies assessing safety and efficacy of IV t-PA treatment in WUS patients guided by neuroimaging to estimate time of symptom onset. The authors used PubMe...

A Case of Cerebral Venous Thrombosis and Deep Venous Thrombosis Due to Hyperthyroidism with Increased Factor VIII Activity
A 48-year-old woman was admitted to our hospital because of headache and fever. She was diagnosed with aseptic meningitis. Five days later, she had a seizure and developed left hemiparesis. Magnetic resonance imaging showed hyperintensity in the right parietal area on fluid attenuated inversion recovery imaging. She was diagnosed as having cerebral venous thrombosis (CVT) because the suprasagittal sinus was invisible on the venographic studies. Moreover, deep venous thrombosis (DVT) was detected in her left lower extremity.

MRI-Based Predictors of Hemorrhagic Transformation in Patients With Stroke Treated by Intravenous Thrombolysis
Clinical and biological risk factors for hemorrhagic transformation (HT) after intravenous thrombolysis (IT) have been well established in several registries. The added value of magnetic resonance imaging (MRI) variables has been studied in small samples, and is controversial. We aimed to assess the added value of MRI variables in HT, beyond that of clinical and biological factors. We enrolled 474 consecutive patients with brain infarction treated by IT alone at our primary stroke center between January 2011 and August 2017. Baseline demographic, clinical, biological, and imaging characteristics were collected. MRI variab...

Cerebral Venous Sinus Thrombosis Score and its Correlation with Clinical and MRI Findings
Background: It is plausible that extent of cerebral venous sinus thrombosis (CVST) may determine clinical severity, magnetic resonance imaging (MRI) lesion, and outcome, therefore this study was undertaken. Methods: A total of 160 CVST patients were included and their clinical details, risk factors, Glasgow Coma Scale score, and parenchymal lesion on MRI were noted. The extent of venous sinus thrombosis on magnetic resonance venography was assessed by using CVST score which was computed giving 1 point for each thrombosed sinus and 3 points to superior sagittal sinus (SSS).

Rapid Disappearance of Intraventricular Mobile Structures with Steroids in Eosinophilic Granulomatosis with Polyangiitis
Endomyocarditis in Eosinophilic granulomatosis with polyangiitis (EGPA) is a rare complication, commonly involving an apical mass compatible with a thrombus. However, no previous report has discussed mobile structures detected by echocardiography in a patient with EGPA. A 53-year-old man with asthma presented with low-grade fever, consciousness disturbance, and vomiting. Magnetic resonance imaging showed multiple acute infarctions in the bilateral cerebrum and cerebellum. Remarkable eosinophilia was observed, and transthoracic echocardiography showed multiple mobile structures originating from the left ventricular septum.

Dural Sinus Thrombosis with Nonsymptomatic Persistent Falcine Sinus: A Case Report
A 24-year-old woman was admitted to our hospital after convulsive status epilepticus. A cerebral magnetic resonance venography revealed a persistent fetal falcine sinus. Additionally, the posterior third of the superior sagittal sinus was hypoplastic and the abnormal deep venous drainage was accompanied. These abnormalities had already been detected by magnetic resonance imaging several years ago. In the present scan, we discovered a sinus thrombosis in the hypoplastic superior sagittal sinus. In the cerebral angiography, we observed delayed venous return in the left parieto-occipital lobe and hypothesized that cerebral ve...

Endomyocardial fibrosis and apical thrombus in patient with hypereosinophilia
A 76-year-old woman with a history of left semiovale ischaemic lacunar stroke was admitted to hospital for suspected acute coronary syndrome and transient ischaemic attack. The previous year, echocardiography had shown normal results. Neither coronarography nor encephalic computed tomography showed significant lesions. Brain magnetic resonance imaging revealed multiple strokes in different arterial regions, with probable cardioembolic origin (Panel A).

T2*-Weighted MRI Detected Dilated Cerebral Veins in a Patient With Acute-Phase Cerebral Venous Sinus Thrombosis —A Case Report
We describe a 45-year-old man who presented with nausea, vomiting, and strong occipital headache on the right side. Although no abnormalities on neurological examination or computed tomography imaging were found on admission, peripheral blood cell counts showed polycythemia (hemoglobin 20.6 g/dL) and electrocardiography demonstrated atrial fibrillation. Therefore, anticoagulant treatment with heparin was started immediately. On the following day, the occipital headache continued. Brain T2*-weighted (T2*WI) magnetic resonance imaging (MRI) and, to a lesser extent, susceptibility-weighted imaging showed dilation of numerous ...

Patent Foramen Ovale and Ischemic Stroke in Patients With Pulmonary Embolism: A Prospective Cohort Study.
Conclusion: Frequency of recent ischemic stroke in patients with symptomatic PE was higher in patients with PFO than in those without PFO. This finding supports the hypothesis that paradoxical embolism is an important mechanism of ischemic stroke in patients with PFO. Primary Funding Source: French Ministry of Health.

Intravenous Thrombolysis in Posterior Circulation Stroke
Conclusions: Up to date, no data about PCIS and IVT are available from RTCs. Based on limited results from retrospective clinical studies and case series, IVT is safer for use in PCIS than in ACIS. Patients with brainstem ischemia, vertebral artery occlusion, and absence of basilar or posterior cerebral artery occlusion could be considered for treatment with IVT even in borderline cases. Time to IVT in PCIS seems to be a less crucial factor than in ACIS. IVT for PCIS may be beneficial even after 4.5 h from symptom onset.

Hemodynamic Characteristics Associated With Paraclinoid Aneurysm Recurrence in Patients After Embolization
Conclusions: High peak systolic WSS, OSI and velocity around aneurysm neck areas after embolization of paraclinoidal aneurysms may be important factors leading to recurrence. Introduction Paraclinoid aneurysms are defined as aneurysms arising from the segment of the internal carotid artery (ICA) between the distal dural ring and the origin of the posterior communicating artery. They account for approximately 1.3–5% of all intracranial aneurysms and they comprise the majority of such aneurysms in females (1–3). Hemodynamic characteristics are thought to be the most important risk factors for occurrence...
