background: hemorrhagic transformation (ht) of ischemic stroke (is) is a detrimental complication. this study investigated the association between serum ferritin level and ht in patients with massive is of middle cerebral artery. methods: thirty patients with massive is of middle cerebral artery were enrolled in this prospective cohort study. they were divided into two groups based on the ser...

Background: Asymptomatic hemorrhagic transformation infarct (AHTI) is known as a complication of ischemic attack and maybe occurs in the entire stroke. However, the role of AHTI in the result of the treatment is still not clear, because it is based on the definition of an asymptomatic and not identifiable. The aim of this study was assessment and evaluation frequency of AHTI in acute ischemic s...
BACKGROUND AND PURPOSE Prediction of hemorrhagic transformation in acute ischemic stroke could help determine treatment and prognostication. With increasing numbers of patients with acute ischemic stroke undergoing multimodal CT imaging, we examined whether CT perfusion could predict hemorrhagic transformation in acute ischemic stroke. MATERIALS AND METHODS Patients with acute ischemic stroke...
BACKGROUND AND PURPOSE The contrast volume transfer coefficient (Ktrans), which reflects blood-brain barrier permeability, is influenced by circulation and measurement conditions. We hypothesized that focal low BBB permeability values can predict the spatial distribution of hemorrhagic transformation and global high BBB permeability values can predict the likelihood of hemorrhagic transformatio...
BACKGROUND AND PURPOSE An increased risk of hemorrhagic transformation is a major factor limiting the use of tissue plasminogen activator for stroke. Increased hemorrhagic transformation is also found in animals undergoing transient focal cerebral ischemia with hyperglycemia; this study examined whether hyperbaric oxygen (HBO) could reduce such hemorrhagic transformation in a rat model. METHO...
OBJECTIVE Hyperdense lesions can frequently be observed on the CT obtained immediately after intra-arterial (IA) thrombolysis, and it is sometimes difficult to differentiate contrast extravasation from the hemorrhagic lesions. The purposes of this study are to classify the hyperdense lesions according to their morphologic features and to track the outcome of those lesions. MATERIALS AND METHO...
