Analysis of periinterventional complications of intracranial angioplasty and stenting: A single center experience
Conclusion Our retrospective data analysis suggests that the risk of periinterventional stroke after PTAS of symptomatic intracranial atherosclerotic disease might be reduced by sufficient antiplatelet therapy and optimized management of patients with high risk for reperfusion injury or perforator strokes, including selection of a stenting device adapted to individual vessel morphology.

Rescue Treatment of Thromboembolic Complications during Endovascular Treatment of Cerebral Aneurysms: A Meta-Analysis FELLOWS' JOURNAL CLUB
CONCLUSIONS: Rescue therapy with thrombolytic agents resulted in significantly more morbidity than rescue therapy with glycoprotein IIb/IIIa inhibitors. Tirofiban/eptifibatide resulted in significantly higher recanalization rates compared with abciximab.

Computed Tomography Imaging for Left Atrial Appendage Closure: A Review and Pictorial Essay
Cardioembolic stroke is an important complication of atrial fibrillation (AF). The thrombus responsible for this arises from the left atrial appendage (LAA) in>90% of cases, providing the rationale for device-based LAA closure as a means of thromboprophylaxis. While oral anticoagulant therapy remains the mainstay for reducing the risk of stroke in patients with AF, an increasing number of patients, particularly those ineligible for conventional pharmacotherapy, are being offered percutaneous left atrial appendage closure.

4D-CTA in Neurovascular Disease: A Review REVIEW ARTICLES
This article provides a description of 4D-CTA techniques and a review of the available literature on the application of 4D-CTA for the evaluation of intracranial vascular malformations and hemorrhagic and ischemic stroke. Most of the research performed to date consists of observational cohort studies or descriptive case series. These studies show that intracranial vascular malformations can be adequately depicted and classified by 4D-CTA, with DSA as the reference standard. In ischemic stroke, 4D-CTA better estimates thrombus burden and the presence of collateral vessels than conventional CTA. In intracranial hemorrhage, 4...

Distance to thrombus on MR angiography predicts outcome of middle cerebral artery occlusion treated with IV thrombolysis
Conclusions DT on CE-MRA is reliably measurable, correlates inversely with FLAIR-vascular hyperintensities, and predicts outcome in patients with acute MCA occlusion treated with IVT.

Protected stent retriever thrombectomy prevents iatrogenic emboli in new vascular territories
Conclusion Our study demonstrates two things: First, SWI seems to be more sensitive to detect emboli than DWI and DSA and, second, proximal or distal protected stent retriever thrombectomy seems to prevent iatrogenic embolization into new vascular territories during retraction of the thrombus, but not downstream during mobilization of the thrombus. Both techniques should be investigated and refined further.

Undersized angioplasty and stenting of symptomatic intracranial tight stenosis with Enterprise: Evaluation of clinical and vascular outcome.
CONCLUSION: This preliminary study suggests that using undersized angioplasty and Enterprise stenting may effectively treat high-degree symptomatic intracranial arterial stenosis with favorable clinical and angiographic outcome. PMID: 26542728 [PubMed - as supplied by publisher]

Magnetic Resonance Imaging of Pediatric Neurologic Emergencies
This article reviews the unique pathophysiologic entities affecting the pediatric population and the associated MRI findings. Specifically, utility of emergent MRI and characteristic appearances of traumatic brain injury, traumatic spinal injury, nonaccidental trauma, arterial ischemic stroke, cerebral sinovenous thrombosis, stroke mimics, and central nervous system infections are described.

Optimal Prediction of Carotid Intraplaque Hemorrhage Using Clinical and Lumen Imaging Markers EXTRACRANIAL VASCULAR
CONCLUSIONS: Optimal discrimination of carotid intraplaque hemorrhage requires information on plaque thickness, millimeter stenosis, ulceration, age, and male sex. These factors predict intraplaque hemorrhage with high discriminatory power and may provide clues to the pathogenesis of intraplaque hemorrhage. This model could be used to predict the presence of intraplaque hemorrhage when MR imaging is contraindicated.

Imaging Findings Associated with Space-Occupying Edema in Patients with Large Middle Cerebral Artery Infarcts INTERVENTIONAL
CONCLUSIONS: Extensive proximal occlusion, poor collaterals, and larger ischemic deficits with higher permeability play a role in the development of prominent edema in large MCA infarcts.

Significance of Echocardiographically Detected Central Venous Catheter Tip –Associated Thrombi
Conclusions In this sample with CVC tip–associated thrombi but without PFO or other intracardiac shunts, no embolic or other complications were detected, regardless of anticoagulation status. These data suggest a benign course for such thrombi and that anticoagulation, catheter removal, thrombectomy, and thrombolysis may be unnecessary when catheter tip–associated thrombi are incidentally detected on echocardiography.

Utility of single-energy and dual-energy computed tomography in clot characterization: An in-vitro study.
Conclusions Dual-energy CT with 80/Sn 140 kV had the highest accuracy for differentiating RBC-rich and fibrin-rich in-vitro thrombi. Further studies are needed to study the utility of non-contrast dual-energy CT in thrombus characterization in acute ischemic stroke. PMID: 28604189 [PubMed - in process]

Percutaneous Left Atrial Appendage Closure Devices
AbstractPurpose of ReviewAtrial fibrillation (AF) is the most common arrhythmia in humans. It is a major cause of morbidity and mortality as it impairs cardiac function and is a major risk of embolic stroke. Traditionally, thromboembolic risk of AF has been treated with system anticoagulation with intravenous, intramuscular, or oral anticoagulants. Although the novel oral anticoagulants (NOACs) have revolutionized stroke risk reduction in AF patients, they are associated with a significant risk of bleeding and may be contraindicated in certain patients. Embolic events in AF typically originate from thrombi that form within...

The Role of Neurosonology in the Diagnosis and Management of Patients with Carotid Artery Disease: A Review
ABSTRACT Carotid artery disease (CAD) is a common cause of ischemic stroke with high rates of recurrence. Carotid endarterectomy (CEA) or carotid artery stenting (CAS) are highly recommended for the secondary prevention of symptomatic CAD during the first 14 days following the index event of transient ischemic attack or minor stroke. CEA or CAS may also be offered in selected cases with severe asymptomatic stenosis. Herein, we review the utility of neurosonology in the diagnosis and pre‐/peri‐interventional assessment of CAD patients who undergo carotid revascularization procedures. Carotid ultrasound may provide inval...
