title: [Anticoagulant activity of triiodinated x-ray opaque media (author's transl)].
abstract: The anticoagulant activity of the triiodinated X-ray opaque media iodipamide, iothalamate and diatrizoate on standardized normal human pool plasma was investigated in vitro. We found a dose dependent lengthening of the thrombin time, the reptilase time and the partial thromboplastin time together with a dose dependent drop of the calcium thromboplastin and factor V activity. Iodipamide proved to exert the most pronounced anticoagulant activity of the 3 contrast media tested. The results are interpreted as latent disseminated intravascular coagulation with hyperfibrinolysis following the direct interaction of contrast media with the coagulation enzymes.
