About Hematology Disease and Pregnancy


BIDMC OBGYN specialist meeting with patientPatients with hematologic (blood) conditions, including inherited and acquired blood disorders, can face unique challenges during pregnancy and delivery. Our multidisciplinary team of maternal-fetal medicine specialists, hematologists, anesthesiologists, nurses and social workers provide preconception consultations, as well as advanced prenatal, delivery and postpartum care.

  • Bleeding and coagulation disorders

    • Von Willebrand disease
    • Idiopathic thrombocytopenic purpura (ITP)
    • Other factor deficiencies and platelet disorders
