[Animal experimental studies on the microcirculation of ionic and nonionic x-ray contrast media]

In vivo microscopic (video) investigations on the variability of flow conditions in the myocardium and intestines of anaesthesized normal tension rats after application of various ionic and non-ionic contrast media (Amidotrizoate, Ioxaglate, Iopromide, Iohexol, Iotrolan). Amidotrizoate causes heterogeneous microperfusion and functional shunt vessels (distribution disorder) with the typical symptoms of disturbed microcirculation. Ioxaglate, Iopromide, Iohexol and Iotrolan influence microcirculation differently but always to a far less degree.
