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.

Microbubble-Mediated Sonothrombolysis Improves Outcome After Thrombotic Microembolism-Induced Acute Ischemic Stroke Basic Sciences
Conclusions— Microbubble-mediated sonothrombolysis improved the outcomes of microthrombi-induced acute ischemic stroke. Thus, this method may serve as an attractive adjunct to recanalization therapy for acute ischemic stroke.

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).

CLOTBUST-Hands Free: Initial Safety Testing of a Novel Operator-Independent Ultrasound Device in Stroke-Free Volunteers Clinical Sciences
Conclusions— Our novel device was well tolerated by stroke-free volunteers and did not cause any neurological dysfunction nor did it affect blood brain barrier integrity. The safety and efficacy of the device are now being tested in stroke patients receiving intravenous tissue-type plasminogen activator in phase II–III clinical trials.

Free Floating Left Atrial Ball Thrombus: A Rare Cause of Stroke
We report a case of cardioembolic stroke as a result of free floating left atrial ball thrombus presenting as a complication of rheumatic mitral valve disease. This case highlights that, in all patients with a history of structural heart disease, atrial fibrillation, or rheumatic fever, prompt cardiac ultrasound to exclude free floating atrial thrombus is essential.

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.

Teaching NeuroImages: Extracranial internal carotid artery aneurysm causing embolic stroke
A 42-year-old man with no history of trauma experienced acute numbness in his right arm and leg. A pulsating left cervical tumor was noted on clinical examination. Carotid ultrasound demonstrated significant widening of the left proximal internal carotid artery (ICA) and a large nonocclusive hypoechoic structure compatible with an aneurysm and intraluminal thrombus (figure, B, D, and E). MRI confirmed a fusiform extracranial ICA aneurysm and showed a left-sided small embolic stroke (figure, A and C). The patient underwent anticoagulation with low-molecular-weight heparin and eventually surgical treatment (i.e., resection a...

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).

Ischemic stroke in a patient with Parry-Romberg syndrome (P4.064)
Conclusions:The only other reported patient with PRS and stroke was also found to have a PFO. It is possible that the elevated ANA seen in this patient correlates with propensity towards small venous clots not seen on ultrasound. This may lead to paradoxical emboli and ischemic strokes. It is important to note this potential association between PRS and ischemic stroke in young patients without other known risk factors. It would be worthwhile to treat this subset of patients with medications for secondary stroke prevention.Disclosure: Dr. Ebiana has nothing to disclose. Dr. Singh has nothing to disclose.

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...

Successful Systemic Thrombolysis in an Adolescent With Acute Ischemic Stroke
Conclusions: Despite the lack of evidence regarding the safety and the efficacy of recombinant tissue plasminogen activator in pediatric stroke, this treatment option should be considered, especially in adolescents presenting within 3 hours from symptom onset in centers with consolidated experience in adult thrombolysis.

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.
