Although cerebral edema is a major cause of death and deterioration following hemispheric stroke, there remains no validated biomarker that captures the full spectrum of this critical complication. We recently demonstrated that reduction in intracran

Background Atherosclerotic vertebrobasilar disease is a significant etiology of posterior circulation stroke. The prospective observational VER i TAS (Vertebrobasilar Flow Evaluation and Risk of Transient Ischemic Attack and Stroke) study demonstrate

Abstract W P317: Early CSF Volume Changes Predict Malignant Edema in Large Hemispheric Infarction

Publikováno v: Stroke. 46

Background: Early clinical and radiographic measures (such as NIHSS or early CT hypodensity) incompletely predict which patients with hemispheric stroke will develop malignant cerebral edema. We evaluated whether quantitative changes in volume of CSF

Abstract 12: MR-Oxygen Metabolic Index (OMI) is Superior To Diffusion-Perfusion Mismatch For Predicting Tissue Fate in the Ischemic Penumbra

Publikováno v: Stroke. 44

Background: MR oxygen metabolic index (OMI) is an MR approach closely related to PET-CMRO 2 . We directly compared infarct probabilities in predicted penumbral tissue defined by OMI to that of diffusion-perfusion mismatch (DPM) in a cohort of acute s

Abstract WP246: Time of Onset of Acute Ischemic Stroke As Determined by EMS Personnel is Congruent With Physician-Determined Time of Onset

Autor: David K Tan, Lisa Connor, Andria Ford

Publikováno v: Stroke. 44

Background: Finding witnesses for determination of acute ischemic stroke (AIS) time of onset (ToO) is often time-consuming and prolongs door-to-needle time (DNT). Physicians are reluctant to trust the ToO provided by EMS personnel due to little data
