Abstract
In 26 patients iodixanol, a new nonionic dimer, isotonic to blood in all concentrations, was used as contrast medium in aortofemoral angiography. Half of the patients received contrast medium in a concentration of 270 mg I/ml and the other half 320 mg I/ml. The aim of the trial was to evaluate the safety and tolerability of iodixanol and the radiographic efficacy of the two concentrations. The degree of discomfort, adverse events, changes in serum chemistry parameters, and diagnostic information were assessed. There were no changes or trends of clinical importance in serum chemistry parameters. The side effects were mild and consisted mostly of some sensation of warmth of short duration. No other adverse events were seen. The overall radiographic efficacy did not show any significant difference between the two concentrations. This indicates that iodixanol is safe and well tolerated when used in adult femoral angiography.
