OBJECTIVE Early identification of patients at risk of space-occupying "malignant" middle cerebral artery (MCA) infarction (MMI) is needed to enable timely decision for potentially life-saving treatment such as decompressive hemicraniectomy. We tested the hypothesis that acute stroke magnetic resonance imaging (MRI) predicts MMI within 6 hours of stroke(More)
OBJECTIVE To evaluate the use of fluid-attenuated inversion recovery (FLAIR) imaging as surrogate marker of lesion age within the first 6 hours of ischemic stroke. METHODS e analyzed FLAIR and diffusion-weighted imaging (DWI) sequences performed within 6 hours of symptom onset in 120 consecutive patients with ischemic stroke with known symptom onset. The(More)
Low recanalization rates and poor clinical outcome have been reported after intravenous thrombolysis (IV-tPA) in carotid-T occlusion (CTO). We studied clinical outcome and imaging findings of MRI-based intravenous thrombolysis in CTO. Data of patients with acute ischemic stroke and CTO treated with IV-tPA within 6 h of symptom onset based on MRI criteria(More)
BACKGROUND Treatment with intravenous tissue plasminogen activator (IV-tPA) is usually not recommended in patients with minor stroke. Clinical and imaging outcome were studied after IV-tPA treatment based on MRI criteria in patients with minor stroke. METHODS Data were analysed retrospectively of acute ischaemic stroke patients with minor stroke (National(More)
In patients with malignant middle cerebral artery infarction (MMI) decompressive surgery within 48 h improves functional outcome. In this respect, early identification of patients at risk of developing MMI is crucial. While the acute diffusion weighted imaging (DWI) lesion volume was found to predict MMI with high predictive values, the potential impact of(More)
Background Nurses have a twofold role in healthcare. On one hand, they provide care to patients who are not able to take care of themselves. On the other hand nurses play a vital role as guardians of patient safety. It is mainly on the second role of nurses that the EU funded RN4CAST project is focusing. Materials and methods Data from more than 33,000(More)
BACKGROUND AND PURPOSE Analysis of procedural results and 30-day outcome after intracranial angioplasty and stenting (ICAS) with the balloon-expandable Pharos Vitesse stent system in carefully selected high-risk patients in two high-volume neurovascular centers. MATERIALS AND METHODS 92 patients scheduled for elective ICAS using Pharos Vitesse between(More)
OBJECTIVES Fluid-attenuated inversion recovery imaging (FLAIR) has been suggested as a surrogate marker of lesion age in acute ischemic stroke. In a subgroup analysis, we evaluated whether the extent of perfusion deficit influences FLAIR lesion visibility and thus plays a role as a confounding variable in the interpretation of FLAIR images. METHODS A(More)
PURPOSE Few magnetic resonance imaging (MRI) studies of stroke have evaluated the value of visual assessment of perfusion/diffusion mismatch, which is crucial for routine application. In this study an attempt was made to visually assess perfusion lesions resembling the acute clinical situation and identify parameters with the highest interobserver(More)
