Subarachnoid hemorrhage (SAH) is an acute cerebrovascular event which can have devastating effects on the central nervous system as well as a profound impact on several other organs. SAH patients are routinely admitted to an intensive care unit and are cared for by a multidisciplinary team. A lack of high quality data has led to numerous approaches to(More)
BACKGROUND Over the past 2 decades, the diagnosis and treatment of brain abscess have been facilitated by a number of technological advancements, which have resulted in a significant improvement of outcome. The aim of this manuscript is to review our experience, to determine the factors related to the outcome, and to improve the therapeutic strategy for(More)
BACKGROUND AND PURPOSE The goal of this study was to examine the effects of hypertonic saline on cerebral blood flow (CBF) in poor-grade patients with subarachnoid hemorrhage. METHODS We administered 23.5% hypertonic saline (2 mL/kg IV) 1 time to 10 patients, 2 times to 7 patients, and 3 times to 1 patient. All patients had transcranial Doppler (TCD),(More)
BACKGROUND AND PURPOSE Statins may improve cerebral vasomotor reactivity through cholesterol-dependent and -independent mechanisms. A phase II randomized controlled trial was conducted to examine the hypothesis that acute pravastatin treatment could improve cerebrovascular autoregulation and reduce vasospasm-related complications after aneurysmal(More)
Blood transfusions and intravenous fluids are commonly employed as rescue therapy for delayed cerebral ischaemia following aneurysmal subarachnoid haemorrhage (aSAH). We sought to determine effects of various fluid supplements on clinical outcome in patients following aSAH. Clinical events and laboratory data of 160 aSAH patients were prospectively(More)
OBJECT Delayed ischemic deficits (DIDs), a major source of disability following aneurysmal subarachnoid hemorrhage (aSAH), are usually associated with severe cerebral vasospasm and impaired autoregulation. Systemic erythropoietin (EPO) therapy has been demonstrated to have neuroprotective properties acting via EPO receptors on cerebrovascular endothelia and(More)
BACKGROUND With the introduction of CT, stereotactic techniques, and broad-spectrum antibiotics, the outcome for brain abscess has dramatically improved. The purpose of this study was to identify prognostic factors by reviewing data on 142 patients with brain abscess. METHODS Clinical data, including age, sex, medical history, duration of symptoms,(More)
Following aneurysmal subarachnoid haemorrhage (SAH), cerebral blood flow (CBF) may be reduced, resulting in poor outcome due to cerebral ischaemia and subsequent stroke. Hypertonic saline (HS) is known to be effective in reducing intracranial pressure (ICP). We have previously shown a 20-50% increase in CBF in ischaemic regions after intravenous infusion of(More)
OBJECT Systemic administration of 23.5% hypertonic saline enhances cerebral blood flow (CBF) in patients with poor-grade spontaneous subarachnoid hemorrhage (SAH). Whether the increment of change in CBF correlates with changes in autoregulation of CBF or outcome at discharge remains unknown. METHODS Thirty-five patients with poor-grade spontaneous SAH(More)
BACKGROUND AND PURPOSE We have previously demonstrated that acute pravastatin therapy after aneurysmal subarachnoid hemorrhage ameliorates vasospasm-related delayed ischemic deficits. This study assesses the effects of pravastatin on the frequency and intensity for rescue therapy, length of inpatient stay, and long-term outcome at 6 months. METHODS Eighty(More)
