Abstract
Patients requiring aortography frequently suffer from generalized arteriosclerosis. Uncontrolled hypotension is therefore clearly undesirable, especially if associated with myocardial depression. Significant hypotension was observed following the use of conventional ionic contrast media, Urografin 370 and Cardioconray, and occurred following every injection in this study. Metrizamide, a non-ionic contrast medium, was found to be associated with a smaller fall in blood pressure of a shorter duration.
