Third trimester fetal intracranial hemorrhage owing to vitamin K deficiency associated with hyperemesis gravidarum.
In rare cases, severe fetal vitamin K deficiency bleeding may occur in utero as a result of insufficient vitamin K placental transfer. We present a case of a 32-week-preterm infant born with severe intracranial hemorrhage to a pregnant woman who suffered from hyperemesis gravidarum. Neonatal hematologic status was compatible with vitamin K deficiency whereas the maternal coagulation function was normal. This case emphasizes the potential risk of fetal bleeding owing to vitamin K deficiency in pregnancies complicated with hyperemesis gravidarum. These women should be closely monitored and vitamin K prophylaxis might be considered.
