Filter by:Patients with brain hemorrhage resulting from a ruptured aneurysm (SAH) are at risk of developing a condition called vasospasm, one or two weeks after their hemorrhage. This is a major cause of stroke and death following SAH. A special type of CT scan, called CT perfusion, analyzes regional blood flow in the brain. We hypothesize that CT perfusion scans performed on admission and day 6 post-hemorrhage will enable us to predict which patients will go on to develop vasospasm.
A prospective randomized control trial to examine safety and effectiveness of whole body cooling to a rectal temperature of 33.5 C using phase changing material in neonatal encephalopathy. Effectiveness will be defined by examining the stability of rectal temperature during cooling. Monitoring of vital signs, infection screen, blood counts, coagulation screen, liver and renal function tests, cranial US and MR imaging will be performed on recruited infants to evaluate safety of cooling. EEG will be performed on day 4 and hearing evaluation at discharge. Neurodevelopmental evaluation will be performed at 1 year of age.
To develop adequate blood pressure (BP) lowering strategy after subacute ischemic stroke patients with symptomatic severe intracranial atherosclerosis. Primary hypothesis of this study is that aggressive BP control (lowering systolic BP between 110mmHg and 120mmHg) will not increase the ischemic lesion volumes in hemisphere compared to modest BP lowering (lowering systolic BP between 130mmHg and 140mmHg) in the patients with symptomatic severe intracranial atherosclerosis.
Through this study, the investigators are to prove that Cilostazol effectively prevent cardiovascular events in ischemic stroke patients with high risk of cerebral hemorrhage, along with no significant increase in the risk of occurrence of hemorrhagic side effects. The primary hypothesis of this study is; Cilostazol alone or with probucol will reduce the risk of cerebral hemorrhage without increase of cardiovascular events compared to aspirin in the ischemic stroke patients with symptomatic or asymptomatic old cerebral hemorrhage. This study will prove the superiority of cilostazol on the prevention of cerebral hemorrhagic events without increasing the cardiovascular events against aspirin and the superiority of probucol on the prevention of overall cardiovascular events.
