Ioxaglate, a new low osmolar contrast medium used in femoral angiography.

Ioxaglate, a new monoacid, dimeric contrast medium was compared with diatrizoate (Urografin 60%) in a series of 61 femoral angiographies. In a double blind group of 34 examinations all patients preferred ioxaglate which caused slight pain in only five cases, whereas after diatrizoate 14 patients felt severe pain (six were unable to keep their legs still) and 12 felt slight pain. Increase in heart rate and decrease in systolic and diastolic arterial blood pressure was seen after both contrast medium injections, but significantly less after ioxaglate than after diatrizoate.
