Abstract
Intrauterine constriction of ductus arteriosus is a rare event which often results in severe fetal/neonatal morbidity and mortality. Fetal ductus constriction is usually associated with maternal exposure to non-steroidal anti-inflammatory drugs or structural cardiac lesions. The prognosis depends on the degree and interval of ductal flow obstruction. Detailed history taking is generally required to identify the cause of this diagnosis.We report two cases of fetuses with ductus arterious constriction diagnosed by routine echocardiography in the third- trimester. The cause of the ductus arterious constriction was identified as excess consumption of black and herbal tea. Around 2 weeks after stopping consumption of these substances, ductal constriction was reversed and hemodynamic values returned to normal. Pregnant women and clinicians should be sensitized to the effects of excess consumptions of foods with high concentrations of polyphenol.
