background: aneurysm is a blood-filled bulge in the wall of vessels that occurred in abdominal aortic and cerebral vessels. the dilation of artery leads to aneurysm. methods: three dimensional modelling was utilized for a patient with cerebral aneurysm and a normal subject, and additional fluid-structural interaction simulation was performed. we consider pulsatile blood velocity as inlet, and b...

1. Cerebral blood flow, oxygen and glucose consumption, hind-limb blood flow and oxygen consumption, blood pressure and heart rate were measured in seven ventilated dogs. 2. Inhalation of 5% C 0 2 caused a significant increase in cerebral blood flow and a significant decrease in cerebral glucose utilization. 3. Isoprenaline infusion (0.4 pg kg-I min-') caused a rise in cerebral blood flow, oxyg...

We measured cerebral blood flow using both the radioactive microsphere technique and the cerebral venous outflow technique in dogs anesthetized with chloralase. The effect of sympathetic stimulation on cerebral blood flow was observed during both normocapnia and prolonged hypercapnia using both blood flow techniques. The increase in blood flow with hypercapnia was the same with both methods. Du...

SUMMARY Cerebral blood flow, oxygen, glucose, lactate, and pyruvate metabolism were measured in 13 subjects with completed stroke. Cerebral blood flow and oxygen consumption were reduced, glucose consumption and pyruvate production were normal, and lactate production was increased, suggesting a shift from aerobic to anaerobic cerebral glycolysis. To test this hypothesis, cerebral blood flow and...

Rapid vascular resistance adjustments in the brain and in the circle of Willis have been continuously measured and enhanced by signal averaging methods. Naftidrofuryl, a drug chemically similar to local anesthetics and to beta adrenergic blocking agents, increases local CBF by reducing resistance in brain and in extracerebral supply arteries. It has also been reported to affect brain metabolism...

CEREBRAL BLOOD FLOW Edited by M. Brock, C. Fieschi, D. H. Ingvar, N. A. Lassen, and K. Schurmann. (Pp. xx + 291; 113 figures; DM 58). Springer: Berlin. 1970. Measurement of the cerebral blood flow using isotope techniques is a field in which European centres have held the lead since their introduction by Lassen and Ingvar and by Harper exactly 10 years ago. Conferences at which the initiated ar...

OBJECTIVES Neurological impairment occurs in up to 25% of infants undergoing cardiopulmonary bypass with or without circulatory arrest. Potential causes include alterations in cerebral blood flow, hypoxia and embolisation. During cardiopulmonary bypass, arterial oxygen tension is maintained at levels which under normal conditions cause cerebral vasoconstriction; this is a potential mechanism fo...

Objective: We aimed to evaluate the efficacy of “improved motion-sensitized driven-equilibrium (iMSDE)”-prepared T1-weighted black blood (T1-BB) MRI for monitoring treatment effect with a flow diverter (FD) cerebral aneurysms.
