Diagnostic Yield of Pelvic Magnetic Resonance Venography in Patients With Cryptogenic Stroke and Patent Foramen Ovale Clinical Sciences
Conclusions— Among patients with ischemic stroke/transient ischemic attack and patent foramen ovale, the majority of detected DVTs were in LE veins rather than the pelvic veins and did not differ by stroke subtype. The routine inclusion of pelvic magnetic resonance venography in the diagnostic evaluation of CS warrants further prospective investigation.

Combined lysis of thrombus with ultrasound and systemic tissue plasminogen activator for emergent revascularization in acute ischemic stroke (CLOTBUST‐ER): design and methodology of a multinational phase 3 trial
ConclusionsSince intravenous recombinant tissue‐plasminogen‐activator remains the only medical therapy to reverse ischemic stroke applicable in the emergency department, our trial will determine if the additional use of transcranial ultrasound improves functional outcomes in patients with severe acute ischemic stroke (NCT#01098981).

Sickle Mice Are Sensitive to Hypoxia/Ischemia-Induced Stroke but Respond to Tissue-Type Plasminogen Activator Treatment Basic Sciences
Conclusions—Sickle mice are sensitive to hypoxia/ischemia-induced cerebral infarct but benefit from thrombolytic treatment. An increased resistive index in carotid arteries may be an early marker of sickle cell vasculopathy.

Response to “Measuring the Optic Nerve Sheath Diameter with Ultrasound in Acute Middle Cerebral Artery Stroke Patients”: For Application to Long-Duration Spaceflight (LDSF)
We thank the authors of the study for their contribution to literature and their insights into the utilisation of optic nerve sheath diameter (ONSD) measurements with regards to therapeutic efficacy of thrombolytic therapy (TT) and identification of complications in populations post-MCA stroke. We would like to introduce the discussion of potential translational benefits of this methodology to the field of long-duration spaceflight (LDSF).

What Are the Classifications of Perinatal Stroke?
Discussion Perinatal stroke occurs in about 1:1000 live births and is a “focal vascular injury from the fetal period to 28 days postnatal age.” Perinatal stroke is the most common cause of hemiparetic cerebral palsy and causes other significant morbidity including cognitive deficits, learning disabilities, motor problems, sensory problems including visual and hearing disorders, epilepsy, and behavioral and psychological problems. Family members are also affected because of the potential anxiety and guilt feelings that having a child with a stroke presents, along with the care that may be needed over the child&#...

Early Ultrafast Ultrasound Imaging of Cerebral Perfusion correlates with Ischemic Stroke outcomes and responses to treatment in Mice
Conclusion: We thus provide the proof of concept that in a mouse model of thromboembolic stroke with an intact skull, early ultrafast ultrasound can be indicative of responses to treatment and cerebral tissue fates following stroke. It brings new tools to study ischemic stroke in preclinical models and is the first step prior translation to the clinical settings.

Omentin-1 is Associated with Carotid Plaque Instability among Ischemic Stroke Patients.
CONCLUSIONS: Among ischemic stroke patients, higher omentin-1 levels were inversely associated with carotid plaque instability, but not associated with moderate-severe carotid stenosis or occlusion. Omentin-1 may represent a biomarker for predicting carotid plaque instability of acute ischemic stroke patients. PMID: 29225325 [PubMed - as supplied by publisher]

Knowledge of vascular status for therapeutic decision-making in acute ischemic stroke: which is the role of neurosonology?.
Abstract In the last years there is an increasing interest in the knowledge of vascular status in patients with acute stroke. Detection and localization of an artery occlusion is of great interest for an accurate prognosis and the selection of the most appropriate recanalizing therapy. Neurosonology is a useful diagnostic tool for vascular status study in patients with acute stroke. Different situations where ultrasounds offer a valuable diagnostic information are reviewed, such as middle cerebral artery (MCA) occlusion, 'T' internal carotid artery (ICA) occlusion, 'tandem' ICA-MCA occlusion, monitoring of intra-c...

Cryptogenic Stroke Caused by Pulmonary Arterial Venous Malformation with Massive Right-to-Left Shunt: A Case Report
ConclusionsPAVM is an important risk factor for PE and CS and should not be ignored as a possible etiology in stroke patients without any other risk factors. CTA of the pulmonary artery is the recommended gold standard for diagnosing and locating a PAVM. Thrombolytic therapy within the time window combined with transcatheter device occlusion of arteriovenous malformation and rehabilitation training may benefit the recovery of patients with CS caused by PE resulting from PAVM.

"Fou Rire Prodromique" as the Presentation of a Left Frontal Ischemic Stroke (P02.040)
CONCLUSIONS: Frontal lobe involvement affecting the Broca's area, as we described in our case, has only been described once. We conclude that the patient's laughter attack was the initial manifestation of the stroke suggesting that an acute infarct of Broca's area is capable of producing this unusual clinical presentation.Disclosure: Dr. Rosales has nothing to disclose.

Efficacy of Sonothrombolysis Using Microbubbles Produced by a Catheter-Based Microfluidic Device in a Rat Model of Ischemic Stroke.
Abstract Limitations of existing thrombolytic therapies for acute ischemic stroke have motivated the development of catheter-based approaches that utilize no or low doses of thrombolytic drugs combined with a mechanical action to either dissolve or extract the thrombus. Sonothrombolysis accelerates thrombus dissolution via the application of ultrasound combined with microbubble contrast agents and low doses of thrombolytics to mechanically disrupt the fibrin mesh. In this work, we studied the efficacy of catheter-directed sonothrombolysis in a rat model of ischemic stroke. Microbubbles of 10-20 µm diameter with ...

Cytochrome P450 Genetic Variants and Their Metabolite Levels Associated with Plaque Stability in Patients with Ischemic Stroke.
CONCLUSIONS: Our data demonstrates that CYP450 SNPs are associated with plasma CYP450 metabolite levels and echolucent plaques, indicating that these SNPs may be potential markers for plaque instability. PMID: 26423716 [PubMed - as supplied by publisher]

Review Non-pharmacological strategies for the treatment of acute ischaemic stroke
Early recanalisation and an increase in collateral blood supply are predictors of favourable outcome in acute ischaemic stroke. Since individual responses to intravenous treatment with alteplase are heterogeneous, additional intra-arterial thrombolytic and mechanical endovascular treatment is increasingly given. Despite encouraging findings from single-centre studies, data from randomised clinical trials have not proven the hypothesis that interventional recanalisation leads to a better outcome. Advanced thrombectomy devices, the effect of ultrasound-enhanced thrombolysis, and imaging-guided selection of patients outside t...
