“Liberation treatment” for chronic cerebrospinal venous insufficiency in multiple sclerosis: the truth will set you free
ConclusionCCSVI appears to be a poorly reproducible and clinically irrelevant sonographic construct. “Liberation treatment” has no proven efficacy, may exacerbate underlying disease activity and has been complicated with SAEs. “Liberation treatment” should stop being offered to MS patients even in the settings of RCTs.

Symptomatic free-floating carotid thrombus extending to the skull base
A 58-year-old woman presented to the emergency department with progressive amaurosis fugax with a background of hypertension, hypercholesterolemia, and current smoking. Carotid duplex ultrasound demonstrated an 80%–99% stenosis at the origin of the right internal carotid artery (ICA). CT angiogram revealed a high-grade focal stenosis of the origin of the right ICA with a 7-cm free-floating thrombus (FFT) extending to the skull base (figure 1, video 1 at Neurology.org/cp). The incidence of FFT in patients undergoing carotid imaging has been reported as 0.05%–0.7%.1 It is more frequently reported in men than wome...

Ultrasound Guided Fine Needle Aspiration Biopsy of Thyroid Nodules in Patients taking Novel Oral Anticoagulants.
Conclusions: It has previously been established that patients on historical anticoagulant agents do not need to discontinue therapy prior to minor procedures such as needle aspirations or dental procedures. Therefore, in patients currently taking dabigatran, rivaroxaban, or apixaban, we conclude that is reasonable and safe to continue the novel oral anticoagulant agents prior to USGFNAB of thyroid nodules without major risk of bleeding. This conclusion is based not only on the fact that minor procedures are considered safe in patients on NOACs, but also because patients on historical anticoagulant agents do not need to dis...

MRI, the technology for imaging of thrombi and inflammation.
Abstract Atherosclerosis and its sequelae have a major impact on morbidity and mortality. The rupture of an inflamed atherosclerotic plaque is a crucial event, since it can result in acute thrombotic closure of an arterial vessel, resulting e. g. in myocardial infarction or stroke. Not only detection of early plaque rupture with imminent closure is therefore of clinical interest, but also timely detection of vascular inflammation and atherosclerotic plaque progression. However, plaque inflammation or even plaque rupture without vessel occlusion is not reliably detectable by current imaging techniques. Coronary a...

Duplex sonography for detection of deep vein thrombosis of upper extremities: a 13-year experience.
CONCLUSIONS. Upper-extremity deep vein thrombosis is uncommon among symptomatic Chinese population. The most common sign is swelling and the major risk factor for upper-extremity deep vein thrombosis identified in this study is malignancy. PMID: 25722467 [PubMed - as supplied by publisher]

Diagnosis of an aortic valvular lesion
From the question on page 719 Clinical introduction A 59-year-old woman with hypertension presented with right-sided weakness and vision loss. Her vital signs were normal; cardiopulmonary exam was significant for a systolic and diastolic murmur. MRI of the brain showed multiple chronic bilateral infarctions, and Doppler ultrasound revealed acute left lower extremity deep vein thrombosis. Transthoracic echocardiography (TTE) to determine cardioembolic source of stroke was significant only for severe aortic valve regurgitation. To assess for cardiac vegetations, transoesophageal echocardiography (TEE) was performed (figure 1...

Timing of deep vein thrombosis formation after aneurysmal subarachnoid hemorrhage.
CONCLUSIONS DVT formation most commonly occurs in the first 2 weeks following aSAH, with detection in this cohort peaking between Days 5 and 9. Chemoprophylaxis is associated with a significantly lower incidence of DVT. PMID: 26162047 [PubMed - as supplied by publisher]

Retrobulbar Spot Sign Predicts Thrombolytic Treatment Effects and Etiology in Central Retinal Artery Occlusion Brief Reports
Conclusions— Transbulbar ultrasound is valuable for initial diagnosis and diagnostic workup of CRAO. In the light of inconsistent results of previous thrombolysis trials, ultrasound may identify patients more likely to benefit from thrombolytic treatment.

Etiology of Intracranial Arterial Stenosis: Are Transcranial Color‐Coded Duplex Ultrasound and 3T Black Blood MR Imaging Complementary?
CONCLUSIONSThese two combined imaging techniques might be promising for the differentiation of arteriosclerotic changes from stenosis of another origin, especially when follow‐up TCCD studies are completed early before a possible regression of the atherosclerotic plaque that might be observed 6 months after initial diagnosis.

Magnetic resonance imaging versus transcranial ultrasound in early identification of cerebral injuries in neonatal encephalopathy
Conclusion TCUS is an effective screening tool in detecting the etiology of NE in suspected cases; it is sometimes crucial in critically sick neonates; however, early MRI is mandatory as it can detect precisely the extent of brain injury compared with TCUS alone.

Determining carotid plaque vulnerability using ultrasound center frequency shifts
and Purpose: The leading cause of morbidity and mortality worldwide is atherosclerotic cardiovascular disease, most commonly caused by rupture of a high-risk plaque and subsequent thrombosis resulting in stroke, myocardial infarction or sudden death depending on the affected arterial territory. Accurate, non-invasive methods to identify such lesions known as vulnerable or high-risk plaques are currently sub-optimal. Our aim was to validate a new non-invasive ultrasound method to identify high-risk carotid plaques.

Risk of Venous Thromboembolism in Patients with Large Hemispheric Infarction Undergoing Decompressive Hemicraniectomy
Conclusions The rate of DVT and PE is remarkably high in patients with large hemispheric infarction undergoing decompressive hemicraniectomy despite prophylactic measures. We recommend routine screening for DVT in this population. Interventions beyond the standard prophylactic measures may be necessary in this high-risk group.

Thrombus-Targeted Theranostic Microbubbles: A New Technology towards Concurrent Rapid Ultrasound Diagnosis and Bleeding-free Fibrinolytic Treatment of Thrombosis
Conclusions: We describe a novel theranostic technology enabling simultaneous diagnosis and treatment of thrombosis, as well as monitoring of success or failure of thrombolysis. This technology holds promise for major progress in rapid diagnosis and bleeding-free thrombolysis thereby potentially preventing the often devastating consequences of thrombotic disease in many patients.
