A total of 62 patients were subjected to cerebral angiography and their cardiovascular reactivity was evaluated before, during and after injection of the contrast media by monitoring blood pressure, heart rate and the electrocardiogram. The group consisted of 35 adults and six children with brachial arteriograms and 19 adults and two children with carotid angiograms. All the angiographic procedures were done under local anesthesia, with only the eight children receiving any premedication. The most salient cardiovascular reaction was the demonstration of a biphasic blood pressure response in the subjects undergoing carotid injections and an initial elevation in blood pressure after brachial artery injection. In all but one patient, blood pressures returned to preinjection levels in 40 sec or less after injection. Changes in heart rates were noted to be inverse to alterations in blood pressure, and the electrocardiogram showed only occasional premature ventricular contractions. There were no deaths in this study and of the three patients who developed complications, two recovered completely and one elderly patients with cerebrovascular disease had a residual left hemiparesis.
