Abstract

The purpose of this study was to study changes in intracranial arterial pressure during contrast injection for angiography. Fifteen arteries in 13 patients undergoing angiography for chemotherapy (11 patients) and for embolization of arteriovenous malformations (AVM) (2 patients) were examined with permission. The arterial pressure was measured through a Tracker 18 catheter inserted into the basilar artery or to the top of the internal carotid artery. The contrast medium was injected at 9 ml/ 1.5 s via a 5.5-F catheter or a 7-F guiding catheter placed at the orifice of the vertebral or internal carotid artery. During the injection of contrast medium no peak of a shock wave was detected. Pressure elevation during the injection was 5 mm Hg (mean) in both the systolic and the diastolic pressure in the top of the internal carotid atery, and 3 mm Hg systolic and 7 mm Hg diastolic in the basilar artery. The result proved directly that in man the injection of contrast medium exerts only a minimally harmful influence on aneurysms around the circle of Willis.
