Intracerebral hemorrhagic transformation is one of the most important complications of thrombolytic therapy for acute ischemic stroke. The relationship between changes in markers for the coagulation and fibrinolytic systems and occurrence of hemorrhagic transformation was determined after local intra-arterial thrombolytic therapy using urokinase (UK) (24 patients) or recombinant tissue plasmino...
OBJECTIVE To examine the correlation factors for hemorrhagic transformation after intravenous thrombolytic therapy, so as to improve the forecast about hemorrhagic transformation in the process of thrombolysis, and provide theoretical basis for prognosis of the patients. PATIENTS AND METHODS A total of 1223 patients with intravenous thrombolytic therapy including NIHSS score before intravenou...
The clinical course of patients with hemorrhagic transformation in stroke secondary to spontaneous cervical internal carotid artery dissection (ICAD) has not been elucidated. We report a 36-year-old man with presentation of headache and subsequent left hemiparesis. Magnetic resonance imaging disclosed right ICAD with nearly complete occlusion of the right distal internal carotid artery and infa...
PURPOSE Spontaneous hemorrhagic transformation is common in anterior circulation infarction, but is rarely seen in brainstem infarction. We report a case of massive symptomatic brainstem hemorrhagic transformation in a patient with pontine infarction treated with only antiplatelet agents. CASE REPORT A 59-year-old man presented with acute dysarthria and right sided weakness. His Glasgow coma ...
BACKGROUND AND PURPOSE Thrombolytic therapy was carried out on patients with acute ischemic stroke, and the risk of hemorrhagic transformation was evaluated from the residual cerebral blood flow (CBF) by pretherapeutic single-photon emission-computed tomography (SPECT). METHODS Local intra-arterial thrombolytic therapy was carried out using urokinase or recombinant tissue plasminogen activato...
Pituitary apoplexy is a clinical syndrome with unknown pathogenesis. Therefore, identifying the underlying mechanisms is of high clinical relevance. Tumor necrosis factor alpha (TNF-α) is a critical cytokine mediating various hemorrhagic events, but little is known about its involvement in pituitary apoplexy. Here we show that TNF-α may be an important regulator of hemorrhagic transformation in...
The aim of the present study was to investigate the correlation between the -1562C/T polymorphism in an intron of the matrix metalloproteinase-9 (MMP-9) gene and hemorrhagic transformation of ischemic stroke (IS). Using polymerase chain reaction-restriction fragment length polymorphism, the -1562C/T polymorphisms in 222 patients with IS were detected. The patients were divided into hemorrhagic ...
BACKGROUND Most patients with cardioembolic stroke require long-term anticoagulation. Still, uncertainty exists regarding the best mode of starting long-term anticoagulation. Design, Setting, and Patients We conducted a retrospective review of all patients with cardioembolic stroke admitted to our center from April 1, 2004, to June 30, 2006, and not treated with tissue plasminogen activator. Pa...
OBJECTIVE The effect of prestroke aspirin use on initial severity, hemorrhagic transformation, and functional outcome of ischemic stroke is uncertain. METHODS Using a multicenter stroke registry database, patients with acute ischemic stroke of three subtypes (large artery atherosclerosis [LAA], small vessel occlusion [SVO], or cardioembolism [CE]) were identified. NIH stroke scale (NIHSS) and...
