We investigated whether prolonged high colloid oncotic therapy for two weeks can suppress contusional brain edema. Eighteen patients with cerebral contusion were randomly divided into two groups of patients receiving high oncotic pressure (HOP; 26-30 mmHg) treatment and those receiving normal oncotic pressure (NOP; 22-26 mmHg) treatment. Oncotic pressure(More)
Among nine infants aged less than 4 years with acute subdural hematoma admitted between 1980 and 1991, five required evacuation of a hematoma. Eight of them survived longer than 1 month and the remaining patient who had a hematoma removal died 3 days postoperatively. The four infants who required evacuation of a hematoma and survived longer than 1 month had(More)
We examined the effectiveness of high colloid oncotic pressure (COP) therapy to suppress and/or reduce brain edema associated with putaminal hemorrhage of patients whose clinical grades were grade 3 or 4a classified according to the Japanese neurological grading for putaminal hemorrhage. In the treated group of 11 patients, 25% albumin solution was(More)
We investigated the pathophysiological and morphological responses of anaesthetized rats to fluid percussion brain injury generated by an original midline fluid percussion injury device. Following different grades of trauma, lCBF was measured continuously in the right parietal cortex through a burr hole using laser Doppler flowmeter, and physiological(More)
The propagation of extravasated contrast medium around 6 supratentorial meningiomas with peritumoral white matter of low density (PWL) of Lanksch II-III was investigated by repeated CT scanning at 4 h intervals, following a 1 h drip infusion of 200 ml of Iopamidol. The volume of the expanding peritumoral contrast enhancement was calculated according to a(More)
The pathophysiology of secondary brain damage following experimental traumatic brain injury was investigated by measuring local cerebral blood flow (lCBF), local cerebral glucose utilization (lCGU), and activity of succinate dehydrogenase (SDH), which is a mitochondrial enzyme of the tricarboxylic acid cycle, in the rat brain after moderate lateral fluid(More)
In this study, morphologic changes in brain lesions initiated by moderate lateral fluid percussion injury in rats were investigated chronologically using high-resolution magnetic resonance imaging (MRI) and histopathologic methods. Rats were subjected to moderate fluid percussion injury (average 2.80 +/- 0.48 atmospheres) over the exposed dura overlying the(More)
Nineteen patients, who developed symptomatic vasospasm due to subarachnoid hemorrhage, were treated by hypervolemic-hyperdynamic therapy. The object of this treatment was to increase cardiac output and cerebral blood flow as a result of hypervolemia and the administration of beta-stimulants. During the treatment, if cerebral infarction occurred followed by(More)
