[Effect of cerebral angiography on intracranial pressure in dogs]

Intracranial pressure changes in dogs after intra-arterial administration of contrast media and saline in different amounts at various flow rates were studied by the authors, using continuous epidural pressure recording. In two animals the venous pressure was measured as well. Contrast media and saline alike were found to produce similar intracranial pressure increases when given intravenously though a greater rise with longer-lasting fall and successive rise of the pressure was observed when the former were used. The increase of the amount of the medium or saline had no significant effect on the value of ultracranial pressure.
