The side-effects at phlebography of the lower limb were evaluated using an ionic contrast medium, meglumine-metrizoate, and a non-ionic contrast medium, metrizamide. A post-phlebographic accumulation of 125I-fibrinogen was found in 6 patients examined with meglumine-metrizoate indicating a post-phlebographic thrombosis. Ten patients were examined with metrizamide with no post-phlebographic increase in 125I-fibrinogen uptake. Though the groups are small the difference is statistically significant at the 0.2 per cent level.
