Excessive urinary iodine excretion and borderline hyperthyrotropinaemia were observed in the infant. Moreover, crossing of the fetal bloodbrain barrier was demonstrated by detection of the angiographic material in CSF and thus direct fetal neurotoxic effects cannot be excluded. Conclusion:These widely used contrast media may cross the placenta and accumulate in various fetal tissues in significant amounts causing possible neonatal toxicity. Therefore the perinatal safety of these diagnostic agents should at least be questioned.展开更多
