Summary
Essential thrombocythemia (ET) in pregnancy can lead to severe complications like uterine infarction and hemorrhage. Reducing platelet counts with plateletpheresis or interferon-alpha is suggested for better outcomes.
Area of Science:
- Hematology
- Obstetrics
- Oncology
Background:
- Essential thrombocythemia (ET) is a myeloproliferative neoplasm characterized by elevated platelet counts.
- Pregnancy in women with ET presents unique challenges due to potential hemostatic alterations and risks to both mother and fetus.
Observation:
- A 30-year-old pregnant woman with essential thrombocythemia presented with a high platelet count.
- Despite an uneventful pregnancy managed with aspirin, she experienced severe postpartum hemorrhage and uterine infarction after a cesarean section.
- Microscopic examination confirmed uterine infarction, indicating a potential link to the underlying thrombocythemia.
Findings:
- The patient was diagnosed with essential thrombocythemia (ET) during pregnancy, with elevated megakaryocytes in bone marrow.
- Postpartum hemorrhage and uterine infarction occurred, requiring a hysterectomy and responding partially to platelet transfusion.
- The infant was delivered healthy with normal platelet levels.
Implications:
- This case highlights the significant risks of uncontrolled thrombocythemia during pregnancy, including severe postpartum hemorrhage and uterine complications.
- Management strategies should consider reducing platelet counts through interventions like plateletpheresis or interferon-alpha throughout pregnancy in ET patients.
- Further research is warranted to establish optimal management protocols for pregnant women with essential thrombocythemia to prevent adverse maternal and fetal outcomes.
