Abstract

Pressure volume index(PVI) is a variable reflecting the intracranial hydrodynamic properties and is applied to the management and the prediction of the prognosis in cases of hydrocephalus, head injury, subarachnoid hemorrhage and increased intracranial pressure of other causes. To understand the hydrodynamic properties in acute and chronic phases of the kaolin-injected hydrocephalus in cats, the PVI values were measured in the 6 groups (pre-injection, post-injection 3 days, 1 week. 2 weeks, 3 weeks, 4 weeks). The PVI values were 0.49+/-0.02 ml in control(pre-injection) group, 0.45+/-0.03 ml in 3day group, 0.46+/-0.01 ml in 1week group. 0.48+/-0.04 ml in 2 week group, 0.51+/-0.04 ml in 3 week group and 0.56+/-0.03 ml in 4 week group. Comparing with the values of the control group, the PVI's were decreased in the 3day group and the 1 week group(p<0.05, each) and were increased in the 4 week group(p<0.01).
