Abstract

Purpose: To investigate changes in blood pressure during intracarotid injection of contrast material.

Methods: Two catheters were inserted into the ipsilateral common carotid artery of dogs. The proximal catheter was used for injection of contrast material and the other was positioned distally to monitor blood pressure.

Results: Distal intracarotid pressure rose significantly during injection of contrast material at all rates (5, 7, and 10 mL/s) and at all doses (0.2, 0.5, 0.7, and 1.0 mL/kg). In addition, these blood pressure elevations were shown to be correlated with injection rates and doses. Even when the pressure-monitoring coaxial catheter was advanced into smaller arteries, no decline in the impact of injection was observed.

Conclusion: Intracarotid injection of contrast material causes a temporal elevation of cerebral blood pressure in dogs.
