Thrombosis after phlebography?

Abstract

In contrast to the report by Albrechtsson, we have never seen clinically manifest thrombosis in more than 20,000 phlebographies; only small, clinically insignificant thrombi in a very few cases. The reason is because we have used only 40 cm3 of a 45% contrast medium in connection with heparin precaution. However, there is the possibility that the deep venous valves are damaged. Therefore Amipaque is important for the phlebography. Our test, 20 cm3 45% conventional contrast medium injected directly into varicose veins, always gives a venous thrombosis of about 20 cm. The same amount of Amipaque has never shown a reaction.
