Maternal Fetal Medicine (High-risk Pregnancies)

Maternal-Fetal Medicine, or Perinatology, refers to the specialized care of pregnant women and their fetuses. Our perinatologists are experienced in a wide variety of complex maternal-fetal conditions and will partner with you to keep both you and your baby healthy.

It is our goal as Maternal-Fetal Medicine specialists to care for normal pregnancies as well as those who are high-risk. Our doctors monitor and evaluate women throughout their pregnancies and deliver them at the Johns Hopkins Hospital. Learn more about our Birthing Center.

  • Infectious diseases (to include parvovirus, toxoplasmosis, hepatitis, HIV, and AIDS)
  • Platelet alloimmunization (NAIT or FMAIT) (e.g. Rh negative mother sensitized to an Rh positive fetus)

  • The need for invasive fetal testing procedure(s) or other in utero therapeutic techniques (i.e., blood sampling/transfusion, platelet infusion, fetal bladder stent placement, chorionic villus sampling (CVS) or amniocentesis (amnio) for maternal age or other factors
