Using a CT Angiography Artificial Intelligence Carotid Plaque Morphology Model to Predict Stroke
The gold standard for determining carotid artery stenosis is to calculate stenosis using the North American Symptomatic Carotid Endarterectomy Trial criteria and ultimately plan for medical vs surgical management based on percent stenosis and symptomatic status. Few studies have assessed plaque morphology as an additive tool for stroke prediction. Our study uses an artificial intelligence software in conjunction with a patient's computed tomography (CT) scan of the neck to create a three-dimensional (3D) model of the carotid artery and assess plaque morphology including calcification, intraplaque hemorrhage, matrix, and pe...

Magnetic Resonance Imaging Identified Brain Ischaemia in Symptomatic Patients Undergoing Carotid Endarterectomy Is Related to Histologically Apparent Intraplaque Haemorrhage
Intraplaque haemorrhage (IPH) has been independently associated with a higher risk of future ipsilateral stroke in patients with carotid artery stenosis. Evaluation of plaque characteristics may contribute to risk assessment of recurrent (silent) cerebrovascular events in order to prioritise patients for timing of treatment. It is unknown if patients showing histologically apparent IPH also have increased risk of silent ischaemic brain lesions in the waiting period between index event and revascularisation.

Carotid endarterectomy after systemic thrombolysis in a stroke population
Vascular specialists are increasingly being requested to perform carotid endarterectomy (CEA) after intravenous thrombolysis (IVT) for stroke patients, raising concerns about hemorrhagic complications. Few case series and registry reports have assessed the question, and even fewer studies have included a control group. The aim of this study was to evaluate the overall outcome of patients undergoing CEA after IVT and to compare them with contemporary patients with CEA after simple stroke (non-IVT group).

Invited commentary
Since current guidelines based on randomized clinical trials1-6 have established degree of carotid stenosis as the primary surrogate for stroke risk and indication for carotid endarterectomy or stenting, accurate assessment of the degree of carotid stenosis has been the traditional focus of carotid imaging.7 However, the degree of carotid stenosis is an inadequate assessment of stroke risk, and other key factors for determining carotid plaque vulnerability include intraplaque hemorrhage, plaque rupture, and luminal thrombus.

Carotid Endarterectomy After Systemic Thrombolysis in Stroke Patients: A Retrospective Comparative Analysis
Vascular specialists are increasingly being requested to perform carotid endarterectomy (CEA) after intravenous thrombolysis (IVT) for stroke patients, raising concerns about hemorrhagic complications. Few case series and registry reports have assessed the question, focusing on comparison with symptomatic patients. The goal was to evaluate the hemorrhagic and overall outcomes of patients undergoing CEA after IVT and to compare them with a similar population.

Prevention of Stroke With Ticagrelor in Patients With Prior Myocardial Infarction: Insights from PEGASUS-TIMI 54 (Prevention of Cardiovascular Events in Patients With Prior Heart Attack Using Ticagrelor Compared to Placebo on a Background of Aspirin-Thrombolysis in Myocardial Infarction)
In patients with prior myocardial infarction, ticagrelor 60 mg twice daily reduces risk of stroke without an excess of hemorrhagic stroke but with more major bleeding.

Carotid Atherosclerotic Plaque Characteristics on Magnetic Resonance Imaging Relate With History of Stroke and Coronary Heart Disease
Carotid plaque thickness and stenosis are associated with a history of ischemic stroke and coronary heart disease (CHD). Carotid intraplaque hemorrhage is associated with ischemic stroke but not with CHD.

Urgent carotid intervention is safe after thrombolysis for minor to moderate acute ischemic stroke
Carotid intervention shortly after an acute neurologic ischemic event is being performed more frequently in stroke centers to reduce the risk of recurrent stroke. Thrombolysis with recombinant tissue plasminogen activator (tPA) is offered to select patients with ischemic stroke symptoms who present within 4.5 hours. However, there is a paucity of data as to whether tPA followed by urgent carotid endarterectomy (CEA) or carotid artery stenting (CAS) has an increased risk of complications, particularly intracerebral hemorrhage (ICH).

A patient with multiple paradoxical emboli
We present a case report of simultaneous pulmonary emboli and paradoxical embolism to the cerebellum causing a stroke and severe ischemia to the left leg. This patient had risk factors for thromboembolic events that included autoimmune disease, cancer, and recent pelvic surgery. The presence of a perforate foramen ovale was suspected on his initial presentation and confirmed with echocardiography. For acute leg ischemia, this patient underwent emergent left common femoral embolectomy. The potential benefit of immediate anticoagulation had to be weighed against the risk of hemorrhagic transformation of his cerebellar stroke...

Intraluminal Thrombus, Intraplaque Hemorrhage, Plaque Thickness, and Current Smoking Optimally Predict Carotid Stroke
Optimal discrimination of carotid-source stroke was obtained with intraluminal thrombus, intraplaque hemorrhage, plaque thickness, and smoking history but not ulceration or stenosis.

3D Ultrasonic Tissue Characterization for Asymptomatic Carotid Atherosclerosis
Carotid plaque histology has confirmed that intraplaque hemorrhage and enlarging lipid-cores are important determinants of plaque rupture and stroke. Noninvasive characterization of these features may identify individuals at risk for stroke. Two-dimensional (2D) longitudinal-sectional ultrasound images have been used to predict plaque histology, but a single slice provides limited information. Tissue-characterization from 3D ultrasound imaging may offer more comprehensive information. We developed a clinical 3D ultrasound protocol to quantify plaque composition (hemorrhage, lipid, calcium and fibromuscular tissue), measure...

Progression Rate and Ipsilateral Neurological Events in Asymptomatic Carotid Stenosis
In this study the authors sought to evaluate the yearly rate of change of carotid luminal narrowing as a risk factor for ipsilateral ischemic neurologic events in patients with ≥50% asymptomatic carotid stenosis. Patients were those who took part in the deferred endarterectomy arm of the Asymptomatic Carotid Surgery Trial (ACST). Secondary aims were to establish the annual incidence of progression and regression of luminal narrowing and identify other risk factors associated with ipsilateral neurological events in these patients. This was a retrospective analysis of data derived from the deferred endarterectomy arm of th...

Carotid Plaque MRI and Stroke Risk: A Systematic Review and Meta-analysis
Dedicated magnetic resonance imaging (MRI) of plaque composition offers stroke risk information beyond measurement of luminal stenosis in carotid atherosclerotic disease. Stenosis severity is widely used as a marker for stroke risk in patients with atherosclerotic carotid disease. However, evidence also suggests plaque composition can also predict stroke risk independent of stenosis severity (den Hartog AG et al, Eur J Vasc Endovasc Surg 2013;45:7-21). MRI measurements of plaque composition may help characterize carotid plaques with respect to stroke risk. However, individual studies have been relatively small, and it is ...

Differences and Similarities Between Spontaneous Dissections of the Internal Carotid Artery and the Vertebral Artery
There are clinical, pathologic, and outcome differences in spontaneous dissections of the internal carotid artery vs those of the vertebral artery. Spontaneous cervical artery dissection is a major cause of stroke in younger patients. Spontaneous cervical artery dissection causes up to 25% of all ischemic strokes in patients 15 to 49 years of age (Putaala J et al, Stroke 2009;40:1195-203). Although constitutional and environmental factors are both thought to play a role in spontaneous cervical artery dissection, precise causes are poorly understood. Significant differences between spontaneous internal carotid artery disse...
