Platelet Degranulation Induced by Some Contrast Media Is Independent of Their Nonionic vs Ionic Nature

Acta Radiol Suppl. 1995;399:182-4. doi: 10.1177/0284185195036s39921.


We confirm that the phenomenon of platelet degranulation exists for both iohexol and diatrizoate, as reported earlier. In contrast to previous conclusions, however, we have determined that the degranulation is independent of the nonionic vs. ionic nature of the media per se, since degranulation was neither seen with nonionic iodixanol nor ionic ioxaglate. The degranulation, further, does not significantly augment platelet function, as measured by flowing whole blood platelet aggregometry.
