BACKGROUND Intracerebral microdialysis (MD) was applied in patients with severe subarachnoid haemorrhage treated in a neurosurgical intensive care unit in order to explore their cerebral energy metabolism. METHOD Brain MD fluid levels of glucose, lactate and pyruvate were measured for 3 to 12 days in 20 patients and 2,635 hourly samples were analysed. The(More)
Cerebrospinal fluid (CSF) markers of brain damage are potentially capable of providing quantitative information about the extent of certain neurological injury. The presence of such markers in CSF after brain damage is transient and it is essential to understand their kinetics if they are to be used in clinical practice. In the present study, the CSF(More)
OBJECTIVES Hemicraniectomy in patients with malignant middle cerebral artery (mMCA) infarct may be life-saving. The long-term prognosis is unknown. METHODS Patients with mMCA infarct treated with hemicraniectomy between 1998 and 2002 at three hospitals were included. The criterion for surgical intervention was if the patients deteriorated from awake to(More)
Concentrations of S-100 protein in cerebrospinal fluid (CSF) were measured by a recently developed radioimmunoassay (RIA) in 45 patients with subarachnoid haemorrhage (SAH), 44 with verified ruptured aneurysm. In each of 43 patients 2-15 serial CSF samples were analysed, and in the remainder 1 sample was examined. The concentrations of S-100 protein proved(More)
Focal cerebral ischemia was produced in 45 rats by occlusion of the left middle cerebral artery. Groups of rats were investigated over a long period after occlusion, that is, from a few hours to 42 days after the production of focal ischemia. Light microscopy showed infarcts in the frontoparietal cortex and the lateral caudoputamen. The ischemic changes(More)
The concentration of S-100 protein measured in ventricular cerebrospinal fluid (CSF) from 32 patients with subarachnoid haemorrhage (SAH) during the acute phase was related to features on admission such as the Hunt and Hess neurological scale and the amount of blood at the first computed tomography (CT). The S-100 values were also related to functional(More)
OBJECT Based on the concept that unfavorable clinical outcome after aneurysmal subarachnoid hemorrhage (SAH), to a large extent, is a consequence of all ischemic insults sustained by the brain during the acute phase of the disease, management of patients with SAH changed at the authors' institution in the mid-1980s. The new management principles affected(More)
Changes of neuron-specific enolase (NSE) in cerebrospinal fluid after experimental ischaemic stroke caused by middle cerebral artery occlusion in rat were studied. High enzyme levels were found between the second and seventh day after artery occlusion and they correlated well with the extension of infarct seen in histology. NSE levels in cerebrospinal fluid(More)
The value of S-100 protein as a biochemical marker of the extension of brain damage was studied in a rat model of ischaemic stroke. Increased S-100 levels in cerebrospinal fluid were found between the second and fifth day stroke, and the highest values were noted in animals with largest infarcts. In the acute phase ischaemic stroke S-100 protein in(More)
