Polycythemia vera in pregnancy poses risks, but antithrombotic therapy can prevent complications. This case highlights effective management with low molecular weight heparin, aspirin, and hydroxyurea.

Area of Science:

  • Hematology
  • Obstetrics
  • Maternal-Fetal Medicine

Background:

  • Polycythemia vera is a rare chronic myeloproliferative neoplasm.
  • Pregnancy with polycythemia vera can result in severe maternal and fetal complications.
  • Early diagnosis and management are crucial for favorable outcomes.

Observation:

  • A patient with a history of preeclampsia in prior pregnancies was treated with hydroxyurea for polycythemia vera.
  • During a subsequent pregnancy, hydroxyurea was discontinued, and the patient received low molecular weight heparin and low-dose aspirin.
  • Thrombotic complications necessitated the reintroduction of hydroxyurea.

Findings:

  • Diagnosing polycythemia vera during pregnancy is challenging due to physiological changes.

  • Severe vascular complications may indicate an undiagnosed or preclinical phase of polycythemia vera.
  • A combination of antithrombotic agents and myelosuppressive therapy can manage the condition during gestation.

    • Implications:

    • Antithrombotic treatment, including low molecular weight heparin and aspirin, is vital for preventing adverse outcomes in pregnant patients with polycythemia vera.
    • Hydroxyurea can be safely reintroduced if thrombotic events occur.
    • Timely diagnosis and tailored therapeutic strategies are essential for improving pregnancy outcomes in women with polycythemia vera.
