Background and Purpose: End-stage renal disease (ESRD) requiring hemodialysis carries up to a 10-fold greater risk of stroke than normal renal function. Knowledge on risk factors and management strategies derived from the general population may not be applicable to those with ESRD. We studied a large ESRD population to identify risk factors and outcomes for stroke.
Background and Purpose: Blood pressure variability (BPV) may be an important prognostic factor acutely after stroke. This review investigated the existing evidence for the effect of BPV on outcome after stroke, also considering BPV measurement techniques and definitions.
Background and Purpose: The CHA2DS2VASc score and the Essen Stroke Risk Score are respectively used for risk stratification in patients with atrial fibrillation and in patients with cerebrovascular incidents. We aimed to test the ability of the 2 scores to predict stroke recurrence, death, and cardiovascular events (stroke, transient ischemic attack, myocardial infarction, or arterial thromboembolism) in a nationwide Danish cohort study, among patients with incident ischemic stroke and no atrial fibrillation.
Background and Purpose: In primary intracerebral hemorrhage, the presence of contrast extravasation after computed tomographic angiography (CTA), termed the spot sign, predicts hematoma expansion and mortality. Because the biological underpinnings of the spot sign are not fully understood, we investigated whether the rate of contrast extravasation, which may reflect the rate of bleeding, predicts expansion and mortality beyond the simple presence of the spot sign.
Background and Purpose: Atrial fibrillation (AF) and heart failure frequently coexist and are associated with increased morbidity and mortality. We investigated the prognosis of anticoagulated patients with permanent AF and nonpermanent AF according to preexisting heart failure in the AMADEUS (Evaluating the Use of SR34006 Compared to Warfarin or Acenocoumarol in Patients With Atrial Fibrillation) trial.
Background and Purpose: Cavernous sinus thrombosis (CST) is a rare life-threatening cerebrovascular disease known to cause carotid artery narrowing (CAN) and arterial ischemic stroke. The imaging features of CST and related complications have been reported in adults, but rarely in children.
Background and Purpose: Venous thromboembolism and ischemic stroke are associated with unfavorable fibrin clot structure and function. We hypothesized that denser fibrin networks displaying impaired lysability characterize patients with cerebral venous sinus thrombosis (CVST).
Intracranial aneurysms arise in ≈2% of the population, and their rupture causes 3% of all strokes.1 Their treatment requires safely achieving complete aneurysm occlusion while preserving blood flow in the parent, branching, and perforating vessels. For decades, this task was achieved using classic open approaches, such as the pterional craniotomy (PTC) described by Yasargil and Fox in 1975, which afforded safe and effective exposure of the Circle of Willis through the Sylvian fissure with minimal retraction on the frontal and temporal lobes.2 Supported by the introduction of the operating microscope, this approach gained popularity for treating tumors and aneurysms of the anterior circulation and the basilar tip.
Background and Purpose: The low-dose (0.6 mg/kg) alteplase strategy to treat acute ischemic stroke patients became widespread in East Asian countries, without rigorous testing against standard-dose (0.9 mg/kg) alteplase treatment. Our aim was to investigate the comparative effectiveness and safety of the low-dose versus standard-dose intravenous alteplase strategy.
Objectives: This study sought to investigate acute kidney injury (AKI) following carotid artery stenting (CAS).
A 78-year-old man presented with progressive dyspnea on exertion and syncope. His relevant history included coronary bypass surgery twice. Severe aortic stenosis with left ventricular ejection fraction of 65% was evident on echocardiography. Coronary angiogram showed patent left internal mammary artery and saphenous vein grafts with severe 3-vessel disease.
OBJECTIVE: This article reviews the physical principles of MRI-guided focused ultra-sound and discusses current and potential applications of this exciting technology.
PURPOSE: Arterial spin labeling (ASL) magnetic resonance imaging to assess cerebral blood flow (CBF) is of increasing interest in basic research and in diagnostic applications, since ASL provides similar information to positron emission tomography about perfusion in vascular territories. However, in patients with steno-occlusive arterial disease (SOAD), CBF as measured by ASL might be underestimated due to delayed bolus arrival, and thus increased spin relaxation. We aimed to estimate the extent to which bolus arrival time (BAT) was delayed in patients with SOAD and whether this resulted in underestimation of CBF.
It is important to predict the prognosis of patients with stroke by evaluating risk factors and determining treatment. Recurrent stroke is a major cause of mortality and morbidity in patients with stroke. It is known that recurrent stroke is frequent in patients with ischemic stroke (1,2). The origins of ischemic stroke are variable, and cardiogenic strokes represent 20%–30% of ischemic strokes (3).
Abstract: Imaging is important in the evaluation of patients with degenerative disease and infectious processes. There are numerous conditions that can manifest as low back pain (LBP) or neck pain in a patient, and in many cases, the cause may be multifactorial. Clinical history and physical examination are key components in the evaluation of such patients; however, physical examination has variable sensitivity and specificity.
