Postoperative ischemia is associated with reduced functional independence measured by karnofsky performance score (KPS), which correlates well with overall survival. Other studies suggest that postoperative hypoxia might initiate infiltrative tumor growth. Therefore, aim of this study was to analyze the impact of infarct volume on overall survival and progression free survival (PFS) of glioblas...

Introduction: A vital step in the evaluation of acute and chronic stroke involves volume quantification of the infarct as determined from diffusion-weighted images (DWI) [1]. The routine assessment of infarct size is by visual review of the approximate size reported along with the location of the defect with reference to the brain anatomy. Assessment of the infarct volume is critical to managem...

BACKGROUND AND PURPOSE There is increasing interest in defining stroke lesion volume thresholds to predict poststroke outcome. However, there is a paucity of data on factors that impact the association between critical infarct thresholds volume and outcome. We sought to determine whether lesion thresholds best predicting outcome depend on the degree of preexisting white matter hyperintensity (W...

BACKGROUND AND PURPOSE The National Institutes of Health Stroke Scale (NIHSS) provides a reliable, quantitative measure of ischemic stroke severity and is predicted by the infarct size. We sought to determine whether leukoaraiosis severity affects the association between infarct size and NIHSS. METHODS NIHSS and diffusion-weighted imaging-defined infarct volumes from 312 prospectively enrolle...

background: stroke is the third leading cause of death. hypothermia has been recognized as an effective method in reducing brain injury. in this study, we assessed the effects of granulocyte colony-stimulating factor (g-csf) as a neuroprotective agent and mild hypothermia on mortality, behavioral function, infarct volume, and brain edema in wistar rats. methods: forty male rats were used in fiv...

Intraluminal occlusion of the middle cerebral artery (MCAo) in rodents is perhaps the most widely used model of stroke, however variability of infarct volume and the ramifications of this on sample sizes remains a problem, particularly for preclinical testing of potential therapeutics. Our data and that of others, has shown a dichotomous distribution of infarct volumes for which there had previ...
